How many years after planting does a jujube tree normally bear fruit?

The jujube grows in mountainous areas, hills or plains below 1700 m in altitude. It is a warmth-loving fruit tree with strong drought tolerance and fairly strong waterlogging tolerance, but during the flowering period it requires relatively high air humidity, otherwise pollination and fruit set are hindered. It has a strong demand for light and is fairly sensitive to light response. It adapts well to soil, tolerates poor soil and salinity-alkalinity, but is afraid of wind. Now let us take a look at how many years it takes for a jujube tree to bear fruit!

How many years after planting does a jujube tree bear fruit?

After a jujube sapling is planted, it generally bears fruit in the second year. As the saying goes, "Peaches take three years, plums four, pears five; walnuts and persimmons six or seven; a mulberry tree can feed silkworms in seven years, but a jujube tree can be planted and sold for money." This refers to the short fruiting period of the jujube tree.

How to preserve jujube flowers and fruit

1. Suppress vegetative growth, reconcile the conflict between growth and fruiting, and promote fruit set. Such measures include root pruning, pinching, bud removal, branch thinning, bark girdling, ring cutting, scoring, and fertilizer and water management. Taking these measures can regulate the conflict in nutrient distribution and transport between the tree's vegetative growth and its flowering and fruiting, raise the tree's nutritional level, and ensure that more nutrients are supplied to meet the needs of flowers and fruit.

2. Spray water during the flowering period to raise air humidity. Air humidity during the flowering period should not be lower than 60-70%, otherwise it will have an adverse effect. Spraying in the evening or early morning gives good results, generally combined with foliar fertilizer spraying of 0.3-0.5% urea.

3. Place bees in the jujube orchard to increase pollination agents. Some jujube varieties are self-pollinating and some are cross-pollinating; pollination within a variety or between varieties can both achieve good fruit set, and increasing pollination agents gives good results.

4. Spray plant hormones and trace elements, mainly gibberellin, 2,4-D, paclobutrazol, chlormequat, B9, indolebutyric acid, indoleacetic acid, acetic acid, naphthaleneacetic acid, borax, boric acid, etc.

How can a jujube tree bear more fruit

1. Three sprays during the flowering period: The jujube flowering period is relatively long, divided into three stages - early flowering, full bloom and late flowering - and can last more than a month, that is, from late May to the end of June, generally entering full bloom around June 8. The jujube flowering period likes moisture and fears dryness, but this is exactly when the weather is hot and dry with a lot of wind-blown dust, which easily causes the dense hairs on the jujube flower stigma to decrease and makes a large amount of fine dust stick to the stigma, seriously affecting normal pollination. At the same time, under the harm of dry hot winds, the transpiration of the jujube tree increases. If fertilizer and water are lacking at this time, the stigma can easily wither and drop off. Therefore, spraying pesticides, fertilizer and water during the flowering period can greatly increase the fruit set rate of the jujube tree.

2. Reasonable pruning: Pruning a jujube tree can adjust tree vigor, make full use of nutrients, ensure ventilation and light penetration for the jujube tree, increase the positions that bear fruit, and reduce the number of rotten and dropped fruit, thereby achieving the goal of increasing yield. Pruning a jujube tree is mainly based on thinning, combined with heading and renewal. It should be done as follows: thin out overly dense branches, remove crossing branches, cut off drooping branches, reduce overly tall branches, lightly renew strong trees, heavily renew weak trees, appropriately remove old branches from old trees, and prune young trees around shaping. Pruning should be carried out after the Start of Spring and before the jujube tree buds.

3. Timely girdling: Girdling is ring-shaped bark removal. Girdling can suppress vegetative growth, prevent jujube witches' broom disease, improve the nutritional conditions of jujube flowers and young fruit, and enable flowers and fruit to drop less and set more. Hence the farming proverb, "Cut the tree a few times when it flowers, and the jujube tree will bend at the waist under its load." Girdling a jujube tree generally can increase yield by about 30%. Girdling should be carried out when one third of the jujube flowers are open, at a point 30-40 cm from the ground, with an opening width of 0.5-0.7 cm, deep enough to reach the xylem, but the xylem cambium must not be damaged. The cut should be smooth, with no ragged edges left. After opening, apply an appropriate amount of pesticide to the girdle opening to prevent insect damage. Trees less than 7 years old, with a trunk diameter within 10 cm, or not vigorous should not be girdled. The girdling position should be changed year by year.

4. Pinching the tips of new branches: Pinching the tips of new branches can control disharmonious growth of the jujube tree canopy, help form a reasonable canopy with evenly spaced branches and good ventilation and light penetration, control the rampant growth of branches that do not need to extend, save nutrients, and help increase fruit set and fruit development and growth of the jujube tree. Experiments have shown that after pinching, the longest jujube cluster on a new branch can reach 45 cm and can bear up to 12 fruits, which are large and plump, while on an un-pinched branch the longest jujube cluster is only 25 cm and bears at most 5 fruits. Pinching should be done in mid-to-late May during the sprouting stage of jujube branches, selecting new branches 5-7 cm long that have grown that year in areas where jujube branches are dense.

5. Fertilizing and watering: The jujube tree needs water and fertilizer during the early and late flowering stages. Generally, each mature tree is given 15 kg of cake fertilizer and 1 kg of ammonium bicarbonate or 50 kg of human and animal manure during the early flowering stage, and 1 kg of urea or 1 kg of compound fertilizer during the late flowering stage, which can significantly increase yield. The application method is: dig a ring-shaped trench 40 cm deep and 40 cm wide two meters from the trunk, spread the fertilizer in, fill with enough water, and after the water has seeped in, fill the trench level.

6. Placing bees during the flowering period: The jujube tree is a typical entomophilous flower and cannot pollinate itself or rely on wind pollination, but its nectar is abundant and its fragrance is strong, and bees are the best pollination agent. During the flowering period, place beehives evenly in the jujube orchard with a spacing of no more than 300 m. Bees begin activity at 11°C and are most active at 16-29°C. Using bees to collect pollen and pollinate can greatly increase the fruit set rate. However, during the period when bees are placed in the jujube orchard, it is strictly forbidden to use carbaryl and pyrethroid pesticides that are highly toxic to bees.

▍Plant information

       The jujube tree is a deciduous tree species. Its height is generally about 5 m, and it can reach more than 20 m at its tallest. The bark is gray, brown and various other colors. The branches are smooth, mostly crooked, and have many leaf thorns.

       The jujube leaf is papery, with an ovate character, and can later grow into an elliptical shape, about 3 cm long, with a fairly pointed tip. The flower is yellow-green and blooms in May-July. The fruiting period is August-September.

▍Jujube tree planting time

       The jujube tree has the characteristic of long life; a single jujube tree can grow for more than a hundred years. The best time to plant a jujube tree is May.

       Most plants enter a period of vigorous growth in spring. The jujube tree is fairly drought-tolerant. In April and May the climate is suitable, and planting at this time gives better rooting. An ordinary jujube tree needs to grow for 3 years before it begins to flower and bear fruit normally. A jujube tree planted in May can keep up with the normal flowering and fruiting times in its third year.

       Secondly, jujube trees can be divided directly into autumn planting and spring planting. The spring planting time is May, while autumn planting is before winter, when the soil remains warm and the wounds on the jujube tree's roots heal more easily.

▍How many years does a jujube tree take to bear fruit

       Jujube tree fruiting time: 2-3 years old (in August-September).

       The fruiting time of a jujube tree mostly depends on planting details, as well as variety and regional climate. There are many influencing factors, and the flowering and fruiting periods are not fixed. Depending on the planting method, the fruiting time also varies. A jujube tree grown from a cutting will bear fruit within 3 years, while a variety grown by sowing jujube pits takes as long as about 7 years to bear fruit.

▍Common varieties

       Qiyue Xian: The fruit is round, sweet with fine flesh, and most suitable for fresh eating. The plant's skin is slightly thin, dark red in color, and has no waxy feel. The fruit is rich in nutrients, the pit is fairly small, and the overall edible rate reaches more than 98%.

       Jidan Zao: Its fruit is fairly large, similar in size to an egg. The average weight of each Jidan Zao can reach 30 g, but the jujube's skin is fairly thick and it keeps well in storage.

       Li Zao: The fruit of this variety is fairly large and oblong. The fruit's growth period is about 110 days. The plant needs water to grow, and once it is in a water-deficient state, it easily wilts and dies.

Summary: Today the above article mainly brought you related content on the jujube, giving a detailed introduction to the jujube's planting time and the jujube's fruiting time. Through reading the above, we hope to provide you with useful information.

How many years does a jujube tree take to bear fruit

The jujube is an autumn fruit. Because of its high vitamin content, rich nutritional value and crisp texture, it is deeply loved by consumers. Among fruit trees in our country, the jujube tree has a fairly high fruiting rate, and its fruiting time is quick, but in some regions during its market season there can still be a situation where supply falls short of demand.

How many years does a jujube tree take to bear fruit

It depends on what kind of jujube tree it is. Generally speaking, an ordinary jujube tree does not bear fruit in the same year as the sapling. If it is a grafted jujube sapling, it will bear fruit in 2-3 years. If it is a sapling sprouted from the roots of a jujube tree, it can bear fruit in 3-4 years. Generally, a sapling sown from seed needs about 7 years to bear fruit.

How to increase the fruit set rate of jujube trees

1. Improve the tree's nutrition. Improving the tree's nutrition depends on fertilizing. On the basis of fertilizing in October of previous years, the flower-promoting fertilizer in April and the pre-flowering fertilizer in May are essential. For the flower-promoting fertilizer in April, the amount applied to a mature jujube tree at this time should be 0.5 kg of urea, 1 kg of superphosphate and 0.5 kg of potassium sulfate per tree. For the pre-flowering fertilizer in May, apply 1-1.5 kg of compound fertilizer per fruiting jujube tree to store up enough nutrition for flowering. The flowering period is when the jujube tree needs more water. A pre-flowering watering should be combined with the pre-flowering fertilizing to increase soil moisture and air humidity, so that the tree has sufficient water.

2. Improve the field microclimate. During high temperature and drought at the flowering period, a small amount of water can be applied to raise air humidity and lower the ambient temperature. Clear water can also be sprayed evenly on the flowers and fruit in the evening to increase humidity. The number of sprays depends on the degree of the weather; generally once every 2-3 days, sprayed 3-5 times in succession, can achieve a very good effect. If there is heavy rain during the flowering period, drain promptly after the rain to avoid excessive growth of branches, which consumes too many nutrients.

3. Place bees during the flowering period. Placing bees during the flowering period can increase the fruit set rate by more than 1 time. For the number of bees placed, put 1 box of bees per mu of jujube orchard. In orchards where bees are placed, if pesticides are sprayed before or during flowering, pesticides must be chosen selectively; carbaryl or pyrethroid pesticides that have a killing effect on honeybees must not be used, to avoid poisoning the bees and affecting pollination.

Pruning methods to increase the fruit set rate

Prune reasonably according to the distribution of branches and the density of new branches. Carry this out from jujube budding to early June, and it mainly includes bud removal, pinching and branch thinning. Bud removal means removing from the base the buds that sprout on branches in poor growth positions and that affect the growth of fruit branches; bud removal should start in early May. Pinching means removing the tender tip when the jujube has grown to a certain extent, which can effectively suppress the vegetative growth of the jujube tree and shift it toward reproductive growth. Pinching can increase yield by 5%-10%. The timing of pinching varies with climate conditions in different places and is generally carried out at the beginning of flowering. When pinching, first remove the vegetative branches, and after 5-7 days pinch all the remaining fruit branches that have not been pinched. For weak branches the pinching length is 4-5 cm, and for strong vigorous branches the pinching length is 6-8 cm. Branch thinning means promptly removing rampant branches, overly dense branches, overlapping branches and crossing branches. Thinning branches can reduce nutrient consumption, improve ventilation and light penetration in the canopy, increase the fruit set rate, and improve fruit quality.

Harvesting jujube fruit

Harvesting method: manual picking.

1. Hand picking. Mainly suitable for harvesting jujube fruit for fresh eating and for processing into smoked jujubes, southern jujubes, drunken jujubes, etc. Although it requires more labor, it can ensure the fresh jujubes are not damaged, which is good for storage and processing.

2. Shake-down harvesting. Mainly suitable for harvesting jujube fruit for drying. Generally a bamboo pole or wooden stick is used to shake the jujube branches, and a cloth sheet is spread under the tree to catch the jujubes, so as to reduce damage to the jujube fruit and save labor in picking up the jujubes. When using this method, care should be taken to protect the tree. The shaken positions should be relatively fixed each year to minimize scars, and especially to avoid "opposing scars." In addition, the direction of the pole must not face the direction in which a large branch extends, so as not to break the side branches.

Because jujube trees differ in kind, their fruiting times also differ. Normally, when we plant jujube trees, if we want to increase the fruit set rate, we should start with pruning branches, fertilizing, pollinating and other aspects. The jujube tree is a variety that does not tolerate water accumulation, so drainage in the field must be paid attention to, otherwise it will cause the fruit tree to rot.
