What is the reason why the grape is small? There are other factors besides lack of fat.

There are many reasons for small grape grains, including variety problems, lack of elements, many fruits, unreasonable fertilization and improper management, solutions, varieties: to strengthen the understanding of varieties, we will not buy varieties with small granules. Element deficiency: during the growing period of grapes, foliar fertilizer can be sprayed in time, fruit is more: fruit trees are thinned properly, fertilization is unreasonable: fertilizers should be allocated reasonably and appropriately when fertilizing. Improper management: regular inspection of orchards, ploughing and disinfection, timely carding of plants and prevention and control of diseases and insect pests.

1. Variety problem

There are many varieties of grapes, among which there are varieties with small grains and sour grains, whose yield is not high. Because the genes of the variety cannot be artificially changed, we must have a comprehensive understanding of the variety, so it is not easy to be deceived into buying this variety.

2. Many fruits

When planting, the more fruit, the better. Too much fruit will exceed the load of the tree and require more nutrients, resulting in malnutrition, although the yield increases, but the variety decreases. We need to properly thinning the fruit trees, the quantity is controlled within the bearing range of the trees, so that the fruit can develop better, increase the accumulation of nutrients, and improve the quality.

3. The cause of element deficiency

Grapes need certain trace elements during the growing period, such as iron and calcium, otherwise it will affect the expansion of the fruit. If the trace elements in the soil are missing or too few, we do not supplement them in time when applying fertilizer, which will hinder the expansion of grapes and affect the taste of grapes that are not so sweet. Therefore, we should spray foliar fertilizer in time to supplement the content of trace elements.

4. Improper fertilization

Grape growth needs a lot of nutrients, we need a reasonable amount of topdressing. In order to promote the early maturity of fruit trees and increase their yield, some fruit growers apply excessive nitrogen fertilizer, which will lead to excessive growth of branches and loss of nutrition of the fruit, resulting in malnutrition and poor development of the fruit. therefore, we should rationally allocate the amount of fertilizer and fertilization methods to provide grapes with all the nutrients needed for growth.

5. Improper management

Good orchard management is to ensure the normal growth and development of grapes, so field management is very important. Regular inspection and timely detection of various abnormal conditions, do a good job in the prevention and control of various diseases and insect pests, regular ploughing and disinfection, reduce the source of disease and reduce the incidence of infection. Comb the plant in time, enhance its permeability, properly pinch the heart and wipe the bud to prevent it from competing for nutrients, which is conducive to the growth and development of grapes.
