How to Plant Raspberry Seedlings? A Detailed Guide to Raspberry Cultivation Techniques
Among all fruits, raspberries are also a fruit that everyone loves very much. Now, more and more people are starting to grow raspberries, so how should the seedlings people buy from the market be planted? When growing raspberries, what cultivation techniques are there? Next, the editor will share with you some raspberry cultivation techniques, and I believe these cultivation techniques can be helpful to everyone.
How to Plant Raspberry Seedlings
1. First, choose a flower pot with a diameter of about 30 cm. The height of the pot should be about 30 cm, and make sure the bottom of the pot has drainage holes, and the more drainage holes the better.
2. After the flower pot is ready, we can prepare the nutrient substrate for planting raspberries. We can mix peat soil containing a large amount of fiber with fermented cow dung and a small amount of vermiculite in a 2:1:1 ratio, stir evenly, and put it into the flower pot. Next, we can plant the potted raspberry. First, remove the nutrient cup containing the raspberry seedling, then plant the raspberry seedling into the flower pot prepared in advance. The burial depth should be 1-2 cm deeper than the depth of the raspberry seedling when it was in the nutrient cup. After planting, appropriately prune the excess branches and leaves of the raspberry.
3. Then water thoroughly to ensure the nutrient accumulation of the raspberry branches, so as to achieve the goal of earlier flowering and fruiting. After planting is completed, the raspberry can bloom around June, and then by mid-July the fruit will begin to mature. The fruiting period of raspberries is relatively long and can last until mid-to-late September. During this period, you can freely eat fresh and delicious raspberries.
Raspberry Cultivation Techniques
1. Site selection: Raspberries have low requirements for soil, and generally land can support normal growth, but they grow better in relatively fertile soil; it is best to cultivate in spring and autumn, when the survival rate is highest.
2. Cultivation method: After raking the land level and breaking up the soil finely, if conditions permit, apply sufficient base fertilizer; use a row spacing of 2 m and a plant spacing of 30 cm; then dig holes in straight, equally spaced lines about 15 cm long, wide, and deep; before planting, soak the seedling roots in water for 4 hours, then begin planting, with 1110 seedlings planted per mu; the cultivation method is very simple: spread the seedling roots open and put them into the holes, then cover with soil and tamp it down; the key point is: deep planting and shallow covering; the standard is: the soil covering the seedling roots and around them should not exceed the original water mark on the seedlings when they were in the nursery; where conditions permit, if there is no rain after planting, water thoroughly or cover with plastic film, which can ensure the survival rate.
3. Post-planting management: After raspberry seedlings are planted, the main part that sends out branches is the underground rhizome, and the aboveground part is not as important as with other fruit trees. Therefore, when planting raspberry seedlings, only about 20 cm of the aboveground part (main stem) should be left when pruning, which can improve the survival rate; after planting and before budding, a "soil-sealing pesticide" can be applied to prevent large-scale grass growth; during the raspberry growing period, especially in very arid areas, after watering, loosen the soil shallowly, then use "Gramoxone" or "Paraquat" to control weeds, saving labor and effort with good results.
4. Branch tying: Setting up supports for raspberries is an effective measure for transforming flat fruiting into three-dimensional fruiting: in addition to making branch distribution uniform and improving ventilation and light conditions, the important thing is that supports can enable the plants to bear higher yields, keep fresh fruit from being contaminated by touching the ground, and also bring convenience to soil, fertilizer, water, and harvest management in the raspberry orchard. A relatively simple trellis type: bury a post every 10 m within the raspberry row (hardwood posts, cement posts, or metal posts are all acceptable), and at 1-1.5 m above the ground, stretch a line of (No. 8-14) iron wire, and evenly tie and fix the fruiting canes of the plants (clumps) to the iron wire.
5. Pruning and harvesting. Diguohong raspberry bears fruit in the same year it is planted. After the summer fruit is harvested each July, the canes that have fruited can be cut off from the base, while retaining 3-4 robust basal shoots that grew that year per clump, and thinning out the remaining weak basal shoots to facilitate a bumper harvest. Diguohong raspberry, once planted, can bear fruit alternately for more than a hundred years, and the life cycle of high and stable yield per plant (clump) can reach 20 years. Raspberry fruit ripening is not uniform, which is conducive to harvesting, selling, and deep processing in batches; starting from the beginning of fruit ripening, harvest once every 1-2 days when there is no rain or dew. Harvesting in the morning gives the strongest fragrance.
6. Winter cold protection. In northern cold zones and areas with strong wind and little snow, biennial branches need to be covered with soil for cold protection, to prevent flower buds from freezing and branches from drying out. When covering with soil before freezing, press the selected branches down in one direction, tie them, then cover with soil (10-15 cm thick) and seal tightly. After the thaw in the following spring, remove the cold-protection soil and tie them onto the trellis.
What Types of Raspberries Are There
Red raspberry fruit is round, large, dark red, bright in color, and pleasantly sweet and sour. Black raspberry fruit is purple-black, glossy, strongly fragrant, and sweet. Yellow raspberry is a yellow variation of red raspberry, and its fruit is round with a strong aroma. Good-quality raspberries are firm, plump, and fresh. Soft, juice-leaking, mushy berries may be overripe or moldy. Fresh raspberries should be rinsed briefly before eating, but must never be soaked.
What Are the Advantages of Developing Raspberries
1. Domestically it has just started, while international market demand is large, so there is broad market prospects. Raspberries are drought-tolerant and barren-tolerant, with strong drought resistance, and can be planted on flat land, in courtyards, on hilly and mountainous land, and in barren slopes and gullies; they can be planted intensively, in courtyards, or used as plant hedges; some varieties are especially drought-tolerant, cold-tolerant, and barren-tolerant, with particularly developed root sucker sprouting, and can be listed together with sea buckthorn and goji berry as the three pioneer shrub tree species for soil and water conservation.
2. According to different raspberry cultivars, they can be introduced and cultivated in most provinces and regions of our country. For example, some blackberry varieties can withstand low temperatures of about -17°C and grow well in soil with a pH value of 8.0. Among red raspberry varieties, in addition to extremely strong cold tolerance, some can also be cultivated in subtropical high-altitude areas such as Kunming, or in valleys of the Qinghai-Tibet Plateau. Red raspberries have yellow, purple, and other variant cultivars, but they all belong to the same group. Compared with grapes, raspberry cultivation is more extensive, saves labor and water, has strong resistance to pests and diseases, and has low production management costs; raspberries have a short cycle and high economic benefits. They bear fruit in the same year of cultivation, and enter full fruiting in 3-4 years. The economic life can reach about 20 years.
In the above text, through the editor's introduction, I believe everyone has gained a deep understanding of the methods for growing raspberries. In fact, raspberries are also a very good fruit. After all, raspberries taste very good and have relatively high nutritional value. In daily life, people should also pay attention to nutritional balance and not be picky eaters.
