From the ripening stage of grape shoots to the sprouting stage of the following year, it is a crucial period for further differentiation of grape flower buds, accumulation of nutrients, and laying a foundation for high yields in the coming year. This period should focus on disease prevention and leaf protection, and pay attention to prevention and control of downy mildew, black pox, and rust , brown spot disease and other major diseases and major pests such as mink, Spodoptera litura, grape hawk moth.
To control autumn shoots, early application of basal fertilizer must control the growth of autumn shoots, and apply basal fertilizer in appropriate amounts in a timely manner to ensure a stable tree vigor. The secondary shoots germinated in late August. After the fruit is harvested, the shelter film is removed and a nitrogen-based fertilizer is applied to restore the tree vigor. Generally, about 10 kg of urea is applied per mu. In the middle and late September, in the 60 cm distance from the main trunk, a ditch (about 30 cm in depth) of Shiji Fei, mainly organic fertilizer, is generally used for 100 kg of cake fertilizer per mu, 50-100 kg of phosphate fertilizer, and 2000-3000 kg of human and animal husbandry. And according to the symptoms of nutrient deficiency that occurred during the period from bud growth to harvest, appropriate trace elements were added. The fertilization accounts for about 60%-70% of the total amount of fertilizer needed in the year to increase tree vigor and increase disease resistance.
To master the disease and reasonably control the occurrence of downy mildew, 60% fluoxan manganese 600 times liquid or 72.2% pomegranate 1000 times liquid can be used for prevention and treatment, mainly spraying the opposite side of the blade. When black pox occurs, it can be controlled with 40% DuPont Fuxing 7000x or 5% Milconin 800x. When rust occurs, 15% triadimefon 1500 times or 62.5% cents 800 times liquid can be used for prevention and treatment. When anthrax occurs, it can be treated with 10% Shigao 1500-2000 times liquid or 25% carbon tetrachloride 1000 times. When two or more of the above diseases occur at the same time, in addition to the inability to use a mixture of 5% mildeweng, any one of the above-mentioned control methods for each disease may be used in combination. After 10 days, spray carefully with 1:2:80 Bordeaux mixture and spray every 15-20 days until early November.
Insect pests are found, and insect pests are killed in time. After spraying Bordeaux mixture, insecticides must be sprayed every 3-5 days. Generally, 10% annihilation of 2000-3000 times of liquid or 5% of fast killing of enemy 1000-1500. Times of liquid or 90% trichlorfon 1000-1500 times liquid prevention. Killing the grape barb can be controlled with 25% triazotin 1000-1500 or 1000-1500 times.
