What fertilizer is best for growing strawberries? An introduction to fertilization methods
Strawberry is a perennial herbaceous plant of the genus Fragaria in the rose family (Rosaceae), with stems shorter than or nearly equal to the leaves, densely covered with spreading yellow soft hairs, flowers borne in cymes, and fruit an aggregate fruit. It is widely cultivated throughout China, is rich in nutrients, contains a variety of nutritional substances and has health benefits, and has extremely high cultivation value. Now let's take a look at what fertilizer is best for strawberries!
Do strawberries need a lot of fertilizer?
Strawberries bloom and bear fruit continuously, and from planting to flowering and fruiting they need a relatively large amount of fertilizer. In addition to applying sufficient base fertilizer, fertilizer must also be supplemented at the right time. During the fruit enlargement stage and the beginning of harvest, apply strawberry special fertilizer or diammonium phosphate at 10 kg per mu. Combining this with watering and applying it as a 200-fold liquid fertilizer in furrows gives better results. For fields with good growth, spraying only 0.1-0.2% potassium dihydrogen phosphate 2-3 times also has a certain yield-increasing effect; in principle, do not spray during the flowering stage. The fertilization principle for fruit-harvesting fields is adequate N with emphasis on P and K, and a reasonable ratio must be maintained to obtain higher yields and maximum benefits.
What fertilizer is best for strawberries?
1. Nitrogen fertilizer: Nitrogen fertilizer can promote the vigorous growth of strawberry seedlings. Moldy and insect-damaged beans, peanuts, sunflower seeds, etc. that can no longer be eaten are all very good nitrogen fertilizer materials.
2. Phosphorus fertilizer: Phosphorus fertilizer can make strawberries brightly colored, glossy, and plump. Fish bones, eggshells, meat bones, etc. all contain very rich phosphorus.
3. Potassium fertilizer: Potassium fertilizer can improve strawberries' ability to resist pests and diseases. Water from washing rice, leftover tea water, and water from rinsing milk bottles are all very good potassium fertilizer materials.

Base fertilizer: Before planting strawberries, plow the soil deeply to 25-35 cm, and along with plowing apply commercial organic fertilizer at 450-500 kg per mu or high-quality farmyard manure at 3500-4000 kg, urea at 5-6 kg, diammonium phosphate at 15-20 kg, and potassium sulfate at 5-6 kg.
1. Base fertilizer: Before planting strawberries, deep-plow the soil 25-35 cm, and along with plowing, apply per mu 450-500 kg of commercial organic fertilizer or 3500-4000 kg of high-quality farmyard manure, 5-6 kg of urea, 15-20 kg of diammonium phosphate, and 5-6 kg of potassium sulfate.
2. Topdressing: From when strawberries begin to grow until before the flowering stage, apply urea at 9-10 kg and potassium sulfate at 4-6 kg per mu; during the berry enlargement stage, apply urea at 11-13 kg and potassium sulfate at 7-8 kg per mu; after heavy fruiting, topdress as needed.
3. Foliar fertilizer: Spraying humic acid organic-inorganic liquid compound fertilizer on the leaves before and after the flowering stage of strawberries can increase the fruit-setting rate, improve fruit quality, and increase single fruit weight. Spraying 0.2% calcium sulfate plus 0.05% manganese sulfate at the early flowering and full flowering stages can increase yield and fruit storage performance.
What fertilizer is best for strawberries
Strawberry is a very beautiful fruit, with a bright red exterior dotted with many small pale green specks. Strawberries taste sweet and have high nutritional value, making them one of the fruits people especially like to eat. So do you know how strawberries are grown? What fertilizer is generally used for growing strawberries?
What fertilizer is best for strawberries
1. Base fertilizer: In order to build soil fertility and mature the soil, before planting strawberries plow the soil deeply to 25-35 cm, and along with plowing apply commercial organic fertilizer at 450-500 kg per mu or high-quality farmyard manure at 3500-4000 kg, urea at 5-6 kg, diammonium phosphate at 15-20 kg, and potassium sulfate at 5-6 kg.
2. Topdressing: In order to meet the various nutritional needs of flowering, generally from when strawberries begin to grow until before the flowering stage, apply urea at 9-10 kg and potassium sulfate at 4-6 kg per mu; topdressing during the berry enlargement stage: generally apply urea at 11-13 kg and potassium sulfate at 7-8 kg per mu. After strawberries bear fruit heavily, the nutrients in the plant body become deficient. In order to restore plant growth as quickly as possible and form more new leaves and new roots, topdress as needed.
3. Root-outside topdressing: According to the growth condition of strawberries, the root-outside topdressing method (that is, foliar spraying) can be used for supplementary fertilization. Spraying humic acid organic-inorganic liquid compound fertilizer on the leaves before and after the flowering stage can increase the fruit-setting rate, improve fruit quality, and increase single fruit weight. Spraying 0.2% calcium sulfate plus 0.05% manganese sulfate at the early flowering and full flowering stages can increase yield and fruit storage performance.
Methods for growing strawberries
1. Strawberries are suitable for planting in soil with sufficient sunlight and good drainage. The soil depth should be about 15-20 cm.
2. For large strawberry plants, the row spacing should be 30 cm and the plant spacing about 45 cm. Remove the runners from the plants in time to benefit strawberry fruiting. Strawberry yields are cyclical, so it is best to cultivate some new plants in the first few years of planting.
3. If you do not like managing strawberries, you can plant one strawberry every 45-60 cm, so that the strawberries can spread freely. Of course, it will look a bit messy, and the strawberries will not be large. If you want to avoid this situation, you can appropriately remove some runners.
4. In autumn, spread a layer of soil over the plants to prevent frost damage. After the soil freezes, you can spread dry grass 5-10 cm thick over the plants. By the spring of the next year, after new leaves grow, remove the dry grass. Wait until the weather turns warm and stable, then remove the covering soil on the surface of the plants. But leave some dry grass between the rows to prevent weed growth and maintain soil moisture.
Disease control
1. Leaf spot disease: Also called snake-eye disease, it mainly harms leaves, petioles, fruit stalks, young stems, and seeds. On the leaves it forms small dark purple spots, which after expanding form nearly round or oval lesions with purplish-red-brown edges and grayish-white centers, slightly showing fine rings, making the entire lesion look like a snake eye; no small black granules form on the lesions.
Control measures: Remove diseased leaves and old leaves in time. In the early stage of the disease, use 70% chlorothalonil wettable powder at 500-700 times liquid, and spray again after ten days. Or use 70% mancozeb wettable powder, 200 g per mu mixed with 75 kg of water for spraying.
2. Powdery mildew: It mainly harms leaves, and also attacks flowers, fruits, fruit stalks, and petioles. The leaves curl upward into a spoon shape. Damaged flower buds and petals turn purplish red, cannot bloom or bloom as complete flowers, and the fruit does not enlarge, appearing slender; young fruit loses its luster and hardens. Strawberries harmed near the ripening stage lose their commercial value.
Control measures: On the central diseased plants and around them, focus on spraying 0.3 degrees Baume lime sulfur mixture. After harvest, cut the leaves throughout the garden and spray 70% thiophanate-methyl at 1000 times liquid or 50% Tuzet at 800 times liquid and 30% triflumizole at 5000 times liquid, etc.
The nutritional value of strawberries
Strawberries have very high nutritional value and contain a variety of nutritional elements, such as being rich in amino acids, fructose, sucrose, glucose, citric acid, malic acid, pectin, carotene, vitamin B1, B2, niacin, and minerals such as calcium, magnesium, phosphorus, potassium, and iron. These nutrients have a very good promoting effect on growth and development, and are also of great benefit to the elderly and children.
At the same time, strawberry is also a fruit with a relatively high vitamin C content, containing 50-100 mg of vitamin C per 100 grams, more than 10 times higher than apples and grapes; vitamin C can eliminate the state of looseness and tension between cells, make brain cell structures firm, and make the skin delicate and elastic, and has an important effect on brain and intellectual development. In addition, the carotene in strawberries is an important substance for synthesizing vitamin A, and has the effect of improving eyesight and nourishing the liver. The latest foreign research also points out that strawberries contain an amine substance that has a certain effect on treating leukemia and aplastic anemia.
Foreign scholars have found through research that the active ingredients in strawberries can inhibit the growth of cancer tumors. Therefore, eating some strawberries after a meal can break down food fat, aid digestion, and at the same time also play a certain role in preventing cancer!
Through the above content, we have learned about strawberry cultivation techniques. Strawberries are delicious and nutritious, and their use value is also very high. They can be made into strawberry desserts, strawberry candy, strawberry cookies, and dried strawberries, and there are especially many ways to eat them. Seen this way, isn't growing strawberries quite promising?
When is the best time to fertilize home-grown strawberries, and what fertilizers are needed
The weather at the end of April can be considered neither cold nor hot, without the severe cold of winter or the scorching heat of summer. I also want to remind everyone that the May Day short holiday is coming soon! Today I am in a good mood and will chat with you about how to fertilize strawberries after planting. This has also been a question that flower lovers have asked me recently, so I will take everyone's questions and together let's understand when strawberries should be fertilized after planting and what fertilizer to apply.
When is the most suitable time to fertilize?
1. Base fertilizer
Before land preparation, broadcast it and then plow and ridge. Apply 3-5 cubic meters per mu of decomposed organic fertilizer such as chicken manure or cow manure, and apply 100 kg of Shitianxia 15-15-15 nitro-sulfur-based compound fertilizer.
2. First topdressing
After the seedlings survive and two leaves have unfolded, carry out topdressing to promote early seedling development, promote vegetative growth of the plants, and lay the foundation for flower bud differentiation. Use 20 jin per mu of Shitianxia 15-15-15 nitro-sulfur-based compound fertilizer. The fertilization method is shallow furrow application or hole application, or dissolving the fertilizer in water and applying it.
3. Second topdressing
Apply the second fertilizer before and after covering the greenhouse, using 20-30 jin per mu of Shitianxia 18-9-18 nitro-sulfur-based compound fertilizer.
4. Subsequent topdressing
During the fruit enlargement stage, apply 35 jin per mu of Shitianxia sulfur-based 19-4-22 polypeptide compound fertilizer or nitro-sulfur-based 16-8-21 compound fertilizer to prevent premature aging. It can be applied by flushing with water or by opening furrows and burying, once every half month.
4. Foliar topdressing: Strawberries can be given foliar spraying from sprouting and growth through the fruit development stage, combined with pesticide spraying for half
1. What fertilizer do strawberries need
Generally speaking, nitrogen fertilizer can promote the formation of a large number of leaves and runners, strengthen vegetative growth, and increase fruit size. Nitrogen deficiency turns leaves yellow, with localized scorching and slightly smaller than normal leaves. Phosphorus fertilizer can promote flower bud differentiation and increase the fruit-setting rate. Phosphorus deficiency causes purplish-red spots to appear on the upper leaves, and flowers and fruits tend to be small. Potassium fertilizer mainly promotes fruit ripening, increases fruit sugar content, and improves fruit quality. Potassium deficiency often causes black, brown, and dried areas at leaf edges, becoming scorch-like in severe cases, with old leaves suffering severely, and the fruit is light in color and poor in taste. In addition, strawberries are very sensitive to chlorine, so the use of chlorine-containing fertilizers should be controlled.
2. Fertilizing potted strawberries: For potted strawberries, it is best to apply sufficient base fertilizer before planting. During the strawberry growth period, reasonable fertilization is required to ensure robust plant growth and to produce many flowers, many set fruits, and large fruits. There are many choices for base fertilizer, such as long-acting slow-release fertilizer, and other organic fertilizers, all of which can be used.
Reasonable topdressing for strawberries: Topdressing is probably the choice of most flower lovers, because most flower lovers forget the base fertilizer. To meet the various nutritional needs of strawberries during the flowering and fruiting period, generally from when strawberries begin to grow until before the flowering stage, a general-purpose fertilizer can be applied. If base fertilizer has been used, then fertilization may be omitted. During the strawberry berry enlargement stage, a fertilizer high in nitrogen and potassium can be applied. After strawberries bear fruit heavily, the nutrients in the plant body become deficient. In order to restore plant growth as quickly as possible and form more new leaves and new roots, topdress as needed.
