The garden management after grape harvesting is a problem that some fruit growers can easily overlook. The management of this period is just as important as the management of grape blossoms and fruiting dates. Good or bad management will directly affect grape production next year. The second peak of photosynthesis of the leaves will be observed after the harvest and before the leaves fall, but the photosynthetic efficiency will decline rapidly during the deciduous period. Therefore, we must pay attention to this critical period after weeding, strengthen management, protect leaves, protect leaves, and increase the storage of photosynthetic products. If we ignore the management during this period, it will cause premature leaf loss, photosynthesis will decline, and the nutrients stored in the tree will be insufficient. This will result in late germination and neatness in the next year. It will even lead to inflorescence degradation and less flowering. Otherwise, if we do not pay attention This period of pest and disease control will lead to a large number of bases for overwintering diseases and insect pests, which will increase the difficulty of pest control and prevention and control costs next year. This period of management should focus on the following aspects of the work:
1. We must do a good job of restoring the tree vigor and try to protect the leaves and prevent the leaves from falling off prematurely. Do a good job of topping, snoring, remove tendrils and thin branches and old leaves, reduce nutrient consumption, regulate the flow of tree nutrients, and promote the buds are full of maturity. For thin, weak orchard orchards, foliar fertilizer is sprayed in time.
2, do a good job garden clean, reduce the field pest density. After the harvesting of the grapes is completed, the branches trimmed in the field, the dead leaves removed, the diseased branches, the remaining diseased grains, and the tendrils, the damaged bagging, and the weeds in the garden should be removed. Clear out of the park and deep-buried or burned. In this way, it will help reduce the density of pests and diseases in the park and reduce the incidence of plant diseases and insect pests in the next year.
3, combined with deep tillage soil to apply good autumn fertilizer.
Autumn fertilizer is based on organic fertilizer (usually 2-3 tons of manure per mu or 1 ton of refined organic fertilizer), together with 2-3 packages of controlled-release fertilizer or 1-2 packages of compound fertilizer, granular boron, zinc, Magnesium 2 kg each. Autumn fertilizer application time should be rather sooner rather than later. Early fertilization, high outside temperature and active soil microorganisms are conducive to the decomposition of fertilizers and root absorption, and the production of more organic nutrients, which lays a good foundation for the safe wintering of grapes and the results of next year's growth.
4, control of pests and diseases
Postharvest diseases and insect pests are mainly controlled by downy mildew, powdery mildew, scale insects and borers. The use of pesticides mainly includes Bordeaux fluid, 80% sulfur, 80% mancozeb, and other protective agents (the disease can also be sterilized one to two times. After the agent used protective agent) plus insecticide can be.
5, water management, drainage and irrigation combined, timely drainage in the event of rain, in case of autumn and winter drought, irrigation should be timely, to maintain the soil moisture content of not less than 60%.
