First, how to renovate the raspberry land?
1. Plant raspberries using old mountain orchards or agricultural wasteland. The walls of the mantle are to be repaired before being leveled.
2. Clear all kinds of remaining fruit trees in the garden and thoroughly remove roots, weeds, and exposed stones.
3. Apply 3 to 5 m3 of cooked manure or farmyard manure per acre; if conditions are available, organic fertilizer with fulvic acid as the main raw material and a small amount of compound fertilizer (reduction of 50%) should be used. Sprinkle deeper, smoother, and ridged. Ridge width 50cm ~ 70cm, height 20cm ~ 30cm, ridge spacing is generally 2m ~ 2.5m. Roughly furrows. In particular, pay attention to the smooth drainage of the ditch to prevent it from rot. It is best to take sterilizing measures: Mix it with the appropriate amount of carbendazim (or thiophanate-methyl) in the manure, and throw it into the ground.
Second, how to plant raspberry seedlings?
Raspberry can be planted in spring in Beijing, and it can be planted in spring before the seedlings are thawed in the soil (mid-March to early April), and the soil temperature of 10cm to 20cm is stable at more than 10 oc. After the lignification of the seedlings until the soil is frozen (from October to November) it is better. During the second period, early planting is preferred. The seedlings lose less water and are easy to survive. They will germinate earlier in the spring and grow faster. It is best to control one month before the soil is frozen, but it is easy to “plot†seedlings in the autumn in the north. The ground part is cut off by 20cm to 30cm, and it is buried in the winter after planting in autumn.
According to the local precipitation. With plenty of rainwater, the caverns were opened on the ridges; there was less rainfall, and the caverns were opened inside the ridges. The spacing between the rows was generally 2.5m0.8m (or 2m1m), and 330 acres were planted. Flat planted hole planting, the depth and width of each hole 30cm. The soil is more fertile, and the density can be properly reduced; the soil is relatively poor and the density can be appropriately increased. Raspberry field planting can be waited for lines and other points, can also be planted in small and large lines, Dahang 3.5m, Xiaoxing 0.6, plant spacing 0.4m, 600-1000 per mu control.
The roots of the seedlings were soaked in water for 12-24 hours to ensure sufficient moisture in the seedlings. Add 50g of organic compound fertilizer into the hole and mix it with the soil, so that the root system is stretched and planted, and the shallow root is deeply buried. The root and stem are flush with the ground, and the water is poured on the solid water until the water seeps and the surface layer is evacuated.
In order to shorten the period of seedling sowing and improve the survival rate, it is necessary to diligently pour water and water less to keep the soil moist. With bonsai seedlings, under the condition of shade nets and keeping the soil moist, it can also be planted in variable seasons. In order to improve the unit's efficiency, the soil is more fertile, and some shaded dwarf crops (generally less than 30 cm) can be interplanted between rows. Such as peanuts, leafy vegetables, cabbage, radish and so on.
Third, how to manage fertilizer and water?
The first time is from flowering to young fruit formation, mainly nitrogen fertilizer; the second time after fruit formation, phosphorus and potassium are the main factors; Shiji fertilizer should be in the early fall, mainly in the decomposed farmyard fertilizer, but also can add appropriate amount. Organic fertilizer. The base fertilizer was mixed with soil from the 40-60 cm side of the plant. When applying chemical fertilizers, the soil should have sufficient moisture, and about 0.3 kg of chemical fertilizer can be applied to the 50 cm side of the plant. Spray foliar fertilizer during fruiting period. Experts suggest that the use of forestry fertilizers and microbiological fertilizers as the main method and supplemented by chemical fertilizers are beneficial to high yields and improved soils, and improve fruit quality and sweetness. To achieve pollution-free, green food standards, it is best not to use chemical fertilizers. Ancient methods can be used: For example, soaked soybean (reduced cost) is soaked with boiled water (prevent budding) until swelled (perishable), mixed with phosphorus, potassium, and turfgrass with bactericidal effect, at a distance of 30cm from the plant. An annular groove, point 10 to 20 beans, increase fertility.
Wet, wet, drought-tolerant, avoid water stains. When the drought is watered, the soil moisture is 60% and the depth can reach 40cm. Watering time in summer is best to choose after the temperature drops at 4pm. The principle is that the drought can be poured, and the water can be discharged. Pour frozen water before wintering in the north.
12, how to loosen the grass, raspberry raspberry shallow root plants, hi, breathable soil. To prevent soil compaction during the seedling period, it is necessary to work hard on the topsoil. Especially sticky soil, after rain, after irrigation, must be loosened. Artificial grazing is used to make early leave, diligence, and avoid grass shortage. Between seedlings and seedlings, artificial grasses are mainly used. Between the line and the line, in order to improve efficiency, small machines can be used, with a depth of about 10cm, that is, loose soil and grass. Manual weeding should be preserved for grasses with short dwarf lines, which have advantages over disadvantages and increase efficiency. If you want to raise seedlings, pay special attention to soil and weeding. Do not injure the root buds. Herbicides are used with caution, especially at the seedling stage, and herbicides are prohibited. It is possible to kill the surviving seedlings.
At the same time, planting high-protein legumes between rows, such as alfalfa and white clover, can make natural enemies 1 to 2 generations earlier than harmful insects on beneficial weeds. When pests occur on raspberries, their natural enemies can control their development. By June, the beneficial weeds had "completed their missions." They died. The natural enemies of these pests were transferred to legumes and continued breeding, so that pests could not be fully developed and would not be harmed.
