Second bogey is not reasonable between. Avoid planting high-stem crops such as corn in young orchards, and even less crops with common pests and diseases in fruit trees. Fertilizer management should adopt the principle of “pre-promoting, medium-term relief, and post-control†and should not encourage long-term growth. Prevention and control of pests and diseases should be based on prevention and do a good job of comprehensive prevention and control. For young orchards, it is necessary to grasp the prevention and control of Daqingyeye, which is one of the key measures to prevent "swimming" of saplings.
Three avoid light planting fruit trees, not planting forest belts. In fact, the relationship between the forest belt and the orchard is "benefiting a big piece and affecting one line." Especially in areas where winter and spring are cold and wind and sand are relatively large, orchard shelter belts are particularly important. Therefore, be sure to plant the forest belt before or at the same time.
Four bogey irrigation does not support. According to the growth needs of fruit trees, it is obvious that the water can be used without losing the opportunity to promote the growth of fruit trees. Of course, drainage is also very important.
The five bogey only pay attention to square planting, neglect rectangular planting. The advantages of square planting are: good ventilation and light transmission, but it is not suitable for close planting. With the promotion of dwarf dense planting techniques and the advent of advanced gardening machinery, rectangular planting has attracted more and more attention. Its outstanding advantages are: good ventilation and light transmission, suitable for mechanical operation, suitable for close planting, and not easy to close the park, and it is also convenient for manual operation and management.
Six bogey trees mixed planting, single species, pollination varieties with unreasonable. In the intensively managed production park, taboos such as apples, pears, peaches, and apricots are mixed and planted. Because mixed cultivation is not conducive to management, pests and diseases will cross each other and increase the cost of pest control and management. In addition, fruit trees are cross-pollinated plants, and their rate of self-cultivation is low. Therefore, in a production park, it is required to plant 3 to 5 varieties, which should not be excessive. Http://Content/2eb77b11-c041-4798-afda-5dd465e1a3fe?cType=2
