There are many rainy days. How to manage grapes so that they grow well and get sick less?

If there are many rainy days, the photosynthesis of plants will be weakened, the root system will be bad, and the fruit will be swollen, colored and sweetened.

The following is a brief summary:

1. If there is too much rain, the probability of disease will increase. Therefore, biological bacteria with their own nutrition are applied to the ground to improve the nutrition and beneficial bacteria in the soil, reduce the inhibition on the reproduction of harmful bacteria, improve the soil activity and air permeability, reduce the probability of disease occurrence and improve the stress resistance of plants, and promote the nutritional transformation conducive to fruit expansion and coloring.

2. Many people will use NPK fertilizer, but in order to make better use of the soil, you can use water-soluble fertilizer containing organic matter to take root and nourish the land. This water-soluble fertilizer contains fulvic acid, amino acids, polyglutamic acid, polypeptide enzyme, small-molecule vitamins and sugars extracted by microbial fermentation, and the fruit expansion period is better with low phosphorus, medium nitrogen and high potassium.

3. Foliage fertilizer: amino acid calcium boron foliar fertilizer and potassium dihydrogen phosphate can be used for many times, or they can be used together with a certain magnesium fertilizer or directly with boron calcium foliar fertilizer containing organic titanium, which can improve the photosynthesis of plants and promote the absorption and transformation of nutrients.

4. In order to improve the sweetness and disease resistance of fruit, it can also be combined with spraying selenium-enriched foliar fertilizer with biological bacteria on the leaves. Although selenium can be added to fruit trees, the effect after use is that the sweetness of fruit will be improved, the yield and quality will also change, and the diseases of plants will be reduced a lot.

The above points are mainly managed from the long-term maintenance of soil roots and the transformation of nutrient supply. After fertilization management, the roots of plants will be better, soil fertility will be improved a lot, and the occurrence of diseases will be reduced. It is good to improve the sweetness of swollen fruit.
