The post-harvest management of vineyards is very important. After harvesting, the vines still have a period of growth. If they can strengthen management, they will not only increase the ability of the tree to store nutrients, but also increase the cold resistance of the plants during winter, and they will achieve high yields and stable production the following year. Protection.
First, post-production fertilizer
After the fruit is harvested, depending on the growth of the plant, about 12 kilograms of available nitrogen fertilizer is applied per acre, and 0.3% urea water is sprayed 2-3 times to restore normal growth. If the tree grows vigorously, use it sparingly to prevent new shooters. The autumn base fertilizer is completed from late September to early November. Use groove fertilization.
Second, loose soil to prevent drought
After picking fruit, we should timely cultivating and weeding, while deep-dip. If there is a good 15-20 days of continuous weather, it should be irrigated in time to keep the field holding water no less than 60%.
Third, pest control
The main diseases of grapes are downy mildew, black pox, and rust. After picking fruit, we must continue to focus on disease prevention and control. We can use “new high-fat film†+ fungicides + pesticides to prevent and control. “New high-fat film†can enhance efficacy, and harmless to the tree, neutral, and can Any drug mix. Select drugs as much as possible to use non-polluting agents. In addition, attention should be paid to the prevention and control of insect pests such as chafers, grape hawk moths, and two-leaf leafhoppers.

For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).
Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
