Management measures of grape in three main periods

First, the leading measure in the budding period is to "promote". Before May, pay attention to the cold in late spring and prevent low temperature. Spray 5-degree stone-sulfur mixture to prevent diseases and insects. Do a good job in the reasonable distribution of branches and vines, and the curved branches should be rejuvenated by raising the angle. Comprehensively irrigate "sprout water" and apply quick-acting fertilizer once to promote sprouting and strong buds. During this period, the ground temperature is low, so it is necessary to hoe and loosen the soil shallowly, raise the ground temperature and promote the bud to grow. According to the tree potential, wipe the buds and remove the shade, and choose to leave fruit branches. When choosing to stay, we should go to the weak and suppress the strong and leave the mediocre bud. Second, the leading measure of florescence is "control". From May to June, reclaimed water was watered once a week before flowering, and the ground temperature was increased by ploughing frequently. In order to concentrate nutrients on strong branches and strong ears, the ear with weak disease and small density should be removed, the ear with uniform beauty should be kept, and the ear should be reasonably removed and kept evenly. In order to increase the fruit setting rate, 0.3% borax or gibberellin was sprayed during flowering to protect flowers and fruits. Pour "young fruit water" after Xiehua. Third, the leading measure in the fruit expansion period is to "promote". From July to August, the "timely water" was poured and the available nitrogen fertilizer was applied to expand the fruit. Fungicides such as Bordeaux solution, mancozeb and ethyl aluminum should be sprayed alternately to control leaf and fruit diseases such as downy mildew, black bean disease, white rot, round spot and so on. In mid-late July pouring "grouting water", topdressing phosphorus and potassium fertilizer, in order to strengthen the branches. At the same time, the ear and fruit should be thinned at the right time to make the ear neat and improve the fruit quality.
