The comprehensive management of the orchard should be carried out throughout the whole process of the growth of the fruit trees, regardless of the season, season, season and season. However, I have found that there are many fruit growers who do not pay enough attention to post-harvest management of medium-to-early mature apple orchards. They believe that if they sell, they can relax, and some simply leave it alone. In the special circumstances of the summer and summer droughts this spring and summer, this concept is even more tolerant. I believe that we should strengthen management from the following aspects:
First, pest control. Continuous rain is a prone condition for various pests and diseases. First of all, we must promptly inspect the rot rot of fruit trees and the occurrence of borers and red spiders. In the early stages of various diseases, some small lesions were spotted early, and no knives were needed. Only 200-300 times of Guinness + Roushuitong was used. Use a small brush to gently dilute every 5 to 7 days. . Slightly larger lesions need to be cut with a knife before use. In the case of brown spots, red spiders are best sprayed once with 5000-6000 times of Guinness + Roushuitong 4000 times + Abamectin 3000-4000 times.
Second, nutritional supplements. After harvesting fruit in the orchard, the nutrient consumption of the tree is too large. Nutritional supplement should be carried out in time. It is best to dry it once with fruity friend amino acid + ginkgo. Nutrition and disease prevention both take into account.
Third, strengthen field management. After unloading the fruit, the burden on the tree is reduced, and the shade is gradually rainy. In the middle of August, after the summer shooter grows and grows, the growth of the shoot begins. When the growth of the tree develops, the careful management of the middle and early mature apple tree becomes A special technical problem. For early-maturing and late-maturing varieties, it is only necessary to use the method of transferring, picking, plucking, and splitting in the spring shoots for a long period of time (late May to early June) and summer shoots for a long period of time (late July to early August). Management, while middle-early-appearing apples (for example, the United States and the United States, and the Department of Pediatrics) in the late July-August are the fruitful days of fruit harvesting. Objectively speaking, we have no regard for this, we also It should be noted that the growth characteristics of medium-early-maturing apple trees are characterized by spring shoot growth and weak summer shoots (because the summer shoot growth period is just the result of fruit enlargement, maturity, and the effect of a fruit pressing on the crown). The autumn shoot growth is prosperous and the time is short (only One month) We should not despise this "short" word, but we must attach importance to this "wang" word. If left alone, it will inevitably lead to excessive nutrient consumption, undermine the accumulation of nutrients, and cause aggravating losses and fruiting of the next year. Weakening is not conducive to the early and early stop, weakening the flower buds division, if improper operation, excessive thinning on the back strip and premature blocking of the main branch extension head, will cause the flower buds to be washed down. Annual production cuts, according to my practice in the past two years, the correct approach should be The basis of clear five tree (branches) of the potential for potential titration, be treated differently.
1, for the main branch and the upper and lower parts of the ground from the ground is very close to the overlapping branches of large branches, should be removed after mid-August, so that Wangshu control crown and stable tree vigor is beneficial, because the fruit trees are in autumn and long-term prosperity, The wound will heal quickly, which will help the safety of fruit trees for the winter.
2. For the treatment of the back branches, the strong branches and weak branches do not move, and the focus is on Wangzhi and Wangwang branches. For the main and side branches from the use of production, Wang branch from the base began to take more than one branch, weakening its potential. The imaginary branch adopts branching and diverting to pick up the heart and leaves, but the base does not move, making it rejuvenate. Do not die prematurely on the restrained branch. Until late September, decide to die and use it.
3. For other back branches on the main branch, if the main lateral branch and other branch groups are removed without any influence, there is a drooping of the use space.
4, for the extension of the main and lateral branches, the first flower buds do not move, wait until the winter shear and then shrink, for the visual baldness of the posterior bald.
Fourth, pull the transformation. For those who have not completed the previous transformation or have not reformed yet want to transform it, they should start from mid-August onwards and pay close attention to the transformation of the branch, since this period coincides with the rapid growth of the fruit tree, which has established fast and rapid healing. Another point should be noted that the medium-early-maturing varieties generally have poor healing of saw injuries, so serious injuries caused by sawing and diverting after pulling the branches should be promptly wrapped with plastic film to prevent death.
Fifth, autumn basal fertilizer. In September, the autumnal shoots began to stop and the roots of the fruit trees developed into the third peak. During this period, the fertilization is beneficial to the accumulation of nutrients, which will lay a good foundation for the next spring budding, flowering, and fruit setting, and it will also be beneficial to the root injury caused by fertilization. Heal and grow. It should be noted that while insisting on the use of big three yuan, we should not underestimate the amount of fertilizers used in farms. Generally, the amount of cooked chicken manure or sheep dung should be less than 3,000 pounds, and dry chicken manure should be less than 20 bags. Other diammonium compound fertilizers and other chemical classes are best not to use. The fertilization method should be determined according to the respective conditions, and it can be applied in a depth of 20 centimeters.
