2. Weeding: After planting raspberries, most of them should be done at least three or four times a year within one to three years. They are in the growing season of branches and leaves before March, May, August and beginning of winter. After two years, it is generally only necessary to complete ridging and weeding twice, once in the spring foliage growth period and once after fruit picking. Also, after every precipitation or irrigation, the soil should be turned over to improve the permeability of the soil and prevent the land resources from caking.
3, fertilizer and water: Raspberry growth rate is actually relatively fast, and its fertilization amount is also relatively large. Fertilize at least three or four times a year. They germinate in spring, before flowering, bear fruit in the back row, and pick in the middle and late stage. Manure water can be used for irrigation, and organic fertilizers such as urea solution and ammonium bicarbonate can also be used circularly.
In the middle and late stage of picking, most people generally use farmyard manure or compost to furrow and fertilize. In the germination and fruiting period, it is necessary to carry out integrated irrigation, and when there is more precipitation, the temperature is second, and drainage should be carried out in time. * * *, when encountering the temperature in South Korea, you must remember to irrigate effectively to prevent falling flowers and fruits and endanger the production of raspberries.
4. Pruning: Pruning the branches and leaves of raspberries and plastic surgery are important tasks in management methods. Generally speaking, pruning in spring growth period and pruning after fruit picking in autumn can improve the yield and quality of raspberries. Generally speaking, it is pruned from the withered branches and leaves at the top to let the new branches sprout. The second is to prune off branches, dense branches and diseased branches, and keep strong branches without affecting the permeability of plants.
5. Hedgehog: The branches of raspberries are very soft, and in the fruiting period, most of them bear the total weight of fruits in each method. Therefore, we need to build a support frame in advance to prevent the fruit from loosening on the road, making the fruit dirty and endangering the quality of raspberries. Moreover, the loose branches of raspberries will do great harm to the permeability of farmland and easily cause diseases and pests. Therefore, in the process of leaf growth in spring, we must build a good support frame, bring the leaf to the support frame, and let the support frame share the net weight with it.
The growth habit of raspberry is 1. Natural environment: raspberries are generally born in mountainous areas, beside streams in hilly areas, bushes on hillsides, forest edges and beside rock piles. They thrive in the forests of tung trees and camellia oleifera after barren hills or burning mountains. They like the warm and humid natural environment, and have excellent requirements for the diffuse light of sunlight, low requirements for soil, strong adaptability, fertile soil, strong locking effect of water and fertilizer, and excellent drainage pipes.
2. Conclusion: Raspberry bears fruit early, and it is easy to enter the fruiting period. Generally, it will bear fruit in 2 years after planting and harvest in 3 years. The yield is the highest from April to May every year, and the high-yield period is nearly 15 years. The rhizome is shallow, which is not drought-tolerant, and insufficient water will inhibit growth and fruiting. The flowering period is April-May and the fruiting period is June-July. Excessive evaporation of water content and insufficient water content in water surface soil will directly affect production.
