The reason for the small size of the latest grape

Grape in the fruit is relatively high in sugar content, has a higher nutritional value, usually the larger the fruit, the higher the sugar content. The commodity value will also increase, but many friends will find that most of the fruits are small and sour after planting and harvesting, which seriously affects the quality of grapes. So, what on earth causes the fruit to become smaller? The following editor will talk to you about the reasons for the small size of grape fruit.

1. Variety

There are many varieties of grapes, among which there are varieties with small grains, which are generally sour and have lower yields. Because it contains this gene, we cannot change it, so when we choose a variety, we must have a comprehensive understanding and avoid choosing this variety. Can not fully listen to the seller's words, some may be made up for the sake of sales lies.

2. Element deficiency

The lack of trace elements in the process of grape growth will affect the expansion of the fruit, such as iron, calcium and so on. It may be that there are few or even lack of trace elements in the soil. And when fertilizing, few people will pay attention to the supplement of trace elements, which hinders the expansion of grapes and reduces the sugar content. Therefore, it is necessary to spray foliar fertilizer on fruit trees in time to enhance the content of trace elements in fruit trees.

3. There are many fruits

When planting, many friends think that the more fruit, the better, which can increase the yield, but too much fruit will require more nutrients, and will usually exceed the load of the tree. Lead to malnutrition, increase the yield but reduce the quality of the fruit, no matter how much is useless. Fruit trees should be thinned properly and the number of fruits should be controlled within the bearing range of the trees in order to improve the development of fruits, increase the accumulation of nutrients and improve their quality.

4. Fertilization

Fertilization is a skilled work, grape growth needs more nutrition, so we also need to fertilize properly. However, in order to promote the early ripening of fruit trees and increase their yield, many friends apply too much nitrogen fertilizer, which leads to the growth of grape branches and scramble for the nutrition of the fruit. Lead to lack of nutrition, stunting, it is necessary to have a correct method of fertilization, fertilizer nutrients should be rationally allocated to ensure that it can provide a variety of nutrients needed for grape growth.

5. Management

The field management of grape is very important, and good orchard management can ensure the normal growth and development of grape. Regular inspection of orchards, timely detection of various abnormal conditions, prevention of various diseases and insect pests, regular ploughing and disinfection of orchards to reduce pathogens and reduce morbidity. Comb the plants, enhance the permeability of the orchard, properly pinch the heart and wipe the sprouts, to prevent the loss of nutrition or disperse nutrition. To create a good growth and development environment for grapevines.

The above are the various reasons for the small size of the grape fruit, and the most important reason is that we did not do a good job in the management of the orchard when planting. No attention was paid to the prevention and control of the disease, and there was no regular shaping and pruning of the plant, which affected the growth of the plant in various aspects. Affect the quality of the fruit, this is the end of today's introduction, this article is only for reference, I hope it will be helpful to you.
