Recently, Zhang Xiaoguang, an associate professor of the Division of Drugs and Chemicals of the Yangling Vocational and Technical College, suggested that winter is a crucial period for the prevention and control of cherry plant diseases and insect pests. Fruit farmers should grasp the favorable opportunities for prevention and control, organize prevention and control work, and prevent large-scale occurrence of pests and diseases.
Clear Garden, cut off pests and branches
“Winter pests enter the dormancy period. At this time, the use of artificial and agricultural methods to clean the orchards will help eradicate overwintering pests and pests.†Zhang Xiaoguang said many of the pathogens and pests of fruit trees are concentrated in weeds or dead branches and fallen leaves. , falling fruit, frozen fruit in winter. Therefore, after deciduous fruit trees, weeds, fallen leaves, fallen fruits, and diseased branches in the orchard should be promptly removed, and buried deep or concentrated.
At the same time, in conjunction with winter pruning, cut off those branches with diseases and insect pests, such as diseased branches, dead fruits, dead fruits, etc. After cutting and cleaning and concentrating on burning, we can eliminate the pests that overwintered above. In addition, various aging fruit branches and branch groups that have been growing for many years are also potential sites for wintering diseases and insects, and should be rejuvenated in a timely manner.
Deep turning, scraping
"After deep turning, the pests that have been used to overwinter in the soil can be turned over to the surface for freezing, dying, or being eaten by birds. At the same time, a large number of weeds, fallen leaves, and diseased fruits on the soil surface can be turned to the deep layer of the soil. This not only increases the fat source, but also reduces overwintering diseases and insect pests.†Zhang Xiaoguang said that the general depth of gardening is 30-40 cm, and the closer it is to soil freezing, the better the pest is. This time the pests have entered a dormant state and cannot be re-entered into the winter.
In addition, the rough skin, cracks, and cracks of cherry trees are places where many pests can potentially lurk over winter. Many diseases and pests that damage fruit trees such as rot, ringworm, and spider mites all overwinter in rough cracks. At this point, scraping the bark can remove these diseases and pests. After skinning, whiteners or sprays can be applied and the rough skin can be collected or burned.
White trunk
"The whitening of trunks can reduce the risk of burning and freezing, delay the sprouting and flowering of fruit trees, and avoid the danger of late frost. It can also treat trunk pests and diseases and kill the pests that overwinter in the skin joints." Zhang Xiaoguang said that the calcine was first turned into lime milk. Then add salt, soy flour, lime sulfur, and vegetable oil. If a total amount of 0.1% phoxim emulsion is added to the whitening agent, insecticides have better insect resistance. Whitening time is best twice. The first time after deciduous till the soil is frozen and the second time in early spring. The main part of the white painted areas is mainly trunks. The main base of the branches, the south side of the trunk, and the tree forks are painted on the sunny side. Be careful not to apply them to the buds to prevent burning. The whitening agent should be dry and dilute properly so as not to be lost during coating. After drying, it is not necessary to fall off or fall off.
HGH Products stands for recombinant human growth hormone. HGH is rich in protein, lecithin, cerebral phosphatide, amino acids, vitamins, trace elements, etc. The data show that the combination of these components, both in terms of composition and content proportion, is natural, scientific and reasonable. HGH can promote the synthesis of protein, collagen fibrin and elastin, as well as promote blood circulation and increase the content of nitrogen in cells. Which can promote the skin cells of newborn and split, accelerate wound healing, and at the same time again after renal sodium and water absorption, increase the subcutaneous tissue, the effect of the combination, make the skin more smooth, more flexible, and make them calm, small pore, and to promote the role of facial contour.
