First, define the characteristics of births and manage them in sections. There are two distinct peak periods in the root development of the grape. The first peak period was during the expansion period of flowering fruit, the new shoot accelerated growth, and the root grew vigorously. Post-harvest fruit is the peak of the second growth of the root system. The flower bud differentiation of grapes began from May to June, the physiological differentiation period was April, and the average temperature rose above 12°C. After understanding the rules of the development of grapes, it is imperative to rush ahead and strengthen management between each development peak. Second, highlight the application of basal fertilizer, so that the fat production. The yield of grapes is positively related to the level of fertilization, and the inherent experience is the production of fertilizers. Generally, for every 1000 pounds of grapes produced, 2000 pounds of organic manure is required to be prepared with high-quality decomposition, and phosphorus, potassium, boron, calcium and other trace elements are also applied. In the basal fertilizer, the application rate of nitrogen fertilizer accounts for 60~70% of the whole year, phosphorus fertilizer accounts for more than 80%, and potassium fertilizer accounts for 30~40%. Advocates to cover the straw on the ground of the vineyard. The thickness of the straw is about 20 cm. It can keep warm and protect the weeds and inhibit weeds. After the straw rots, it can also improve the soil. Of course, in addition to basal fertilization, it is also necessary to top-feed the fertilizer once before sprouting, flowering, and setting fruit, and to spray nitrogen, phosphorus, and potash outside the roots. At the same time, in the method of applying basal fertilizer, one is that each grape should not be over-fertilized at one time, and if it is applied, the amount of fertilizer must be controlled; second, the fertilizer must be separated from the root system, and the adult grapes should be fertilized with a furrow applied at a distance of 0 from the main root. .8 meters or more. Third, control the retention of the mother branch, update the main vine. The grape begins to be pruned during the dormancy period and the pruning time is carried out before the leaves fall to the beginning of spring. Pruning is divided into short cuts and updated cuts. The short cut is for the main vine, and the update is for the old vine. For short cuts, 8-12 buds were long, 5-7 buds remained, and 2-3 buds remained short. For varieties with a high number of fruit parts, long vines and medium shoots should be used. For medium or weak varieties, the medium and short shoots are the main methods. To update the pruning, one is to selectively cultivate the vigorous shoots that grow under the main stem of the grape. When the new shoots are able to produce more fruit, cut out the old vines that are already declining; The renewal of vines is going to stay weak, stay on, stay before. Fourth, clean up the debris and reduce the source of the disease. After the arrival of winter, it is necessary to thoroughly clean up the vineyards. First, we must clean up the remaining foliage; second, we must eliminate the net disease; third, we must eliminate the weeds, and then concentrate on deep or burn them. Before the sprouting of the grapes, it is necessary to spray the vines stems, branches, and soil 1 or 2 times thoroughly with Baume's 5 degree lime sulfur to kill germs and reduce the incidence of the disease in the coming year.
