How do you grow raspberries? Share the main high-yield planting techniques of raspberry!

Raspberries, which are often called raspberries, are usually wild and have been artificially cultivated in recent years, so how to grow raspberries? What are the main high-yield planting techniques of raspberry?

What conditions do you need to grow raspberries?

Raspberries are usually born in mountain areas, semi-mountain streams, hillside thickets, forest edges and rocky piles, grow luxuriantly under oil tree and camellia oleifera forests on barren slopes or after burning mountains, like warm and moist light, and require scattered light with good light, but it is better to use slightly acidic soil with fertile soil, strong water and fertility conservation and good drainage to neutral sandy loam, red soil and purple soil.

Second, how to grow raspberries? What are the high-yield planting techniques?

1. Garden construction: choose the land with shelter from the wind and sun, loose soil, high content of organic matter, moist soil and not suitable for stagnant water to build a garden. the garden should be ploughed and leveled before construction, and 2000-4000 kg / mu of farm manure should be applied. The planting method is strip method, with row spacing of 2 meters and plant spacing of 0.4 to 0.8 meters. The size of the planting hole is 30 × 30 × 30 cm. Pay attention to protect the basal buds from damage when planting seedlings. After planting, flat stubble in time, leaving stubble about 20 cm, planting 2-3 plants per hole, to achieve the goal of high yield as soon as possible.

two。 Soil preparation: when planting raspberry, select slightly acidic gentle slope land with deep soil layer, loose fertile soil and good drainage, turn the soil deeply, transplant according to the row spacing of 50 cm × 100 cm or 100 cm × 100 cm, apply sufficient base fertilizer before transplanting, and apply farm manure 3-5 kg per plant.

3. Management: raspberry growth period combined with loosening soil and weeding, topdressing 2-3 times a year, mainly nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer. Apply seedling fertilizer in March, flower fertilizer in April, overwintering fertilizer in November, 15002000 kg of human feces per mu, and pay attention to watering during drought in summer and autumn. The weeds were ploughed and weeded twice from May to June and from August to September every year to reduce the consumption of nutrients and water by weeds so as to promote the robust growth of raspberry trees.

4. Picking buds: when the lateral branch of the new branch occurs from April to May, the terminal bud is removed to promote the growth of the lateral branch, at the same time, the heart of the lateral branch is removed to promote the secondary lateral branch, and the branch is leafy and luxuriant, which increases the fruiting mother branch of the following year and increases the yield. Stand pillars next to each plant during the fruiting period to prevent lodging.

5. Support: raspberry branches are soft, often drooping to the ground, or easy to lodge in case of wind, affecting yield and quality. Therefore, a support is erected in the garden, and the biennial branches are tied to the frame to make the branches receive light evenly and maintain a good permeability in the garden.

6. Fertilizer and water: 2000-3000 kg / mu of farm manure can be applied every autumn and topdressing once during flowering and fruit development to increase fruit yield and promote fruit expansion. Topdressing should be based on available nitrogen fertilizer, with 10-15 kg urea per mu each time. At the same time, borax and zinc sulfate are applied each 1 kg per mu to protect flowers and fruits. Do a good job of drainage and irrigation, timely watering in case of drought, to keep the soil moist. Remove stagnant water in time in case of heavy rain to prevent falling flowers and fruits.

7. Pruning: the top dry part of the two-year-old branch should be cut off in time in spring to make the remaining branches give off strong fruit branches. Thinning the base is too dense and there are diseases and insect pests, leaving 7-8 biennial branches per plant, keeping a reasonable density, conducive to ventilation and light, and ensuring high and stable yield. After fruit picking, the biennial branches were cut off, and the tillers and overdense basal branches were removed to control the total number of branches in the garden.

8. Harvest: raspberries are harvested from mid-May to early June, when the fruit is fully developed and green, and has not yet turned red. Harvest is carried out in batches, and after harvest, stems, leaves, receptacles and other impurities are removed. then blanch it in boiling water for 2 minutes and then remove it, then spread it or dry it. The finished product with intact grain, solid yellow-green color, sour taste and no pedicel leaf chips is preferred.

Generally speaking, raspberry fruit early, easy to enter the full fruit period, generally two years after planting fruit, 3 years of high yield, 4 to 5 years when the highest yield, full fruit period can be as long as 15 years, or more planting prospects.
