What causes small grape berries? Latest analysis

Among fruits, grapes have a relatively high sugar content and high nutritional value; usually, the larger the berry, the higher its sugar content. Its commercial value also rises accordingly. However, many friends find after growing and harvesting that most of the berries are on the small side and taste rather sour, which seriously affects the quality of the grapes. So what exactly causes the berries to become small? Below, the editor will talk with everyone about the causes of small grape berries.

1. Variety

There are many grape varieties, and among them there is no shortage of varieties with small berries. Varieties with small berries are generally rather sour and also have lower yields. Because they carry this gene, it is something we cannot change, so when choosing a variety, we must understand it thoroughly and avoid choosing such varieties. We cannot simply believe everything the seller says; some of it may be lies made up just to make a sale.

2. Nutrient deficiency

A lack of trace elements during grape growth can affect fruit enlargement, such as iron, calcium and so on. It may be that the soil has too few trace elements or is even missing them. Moreover, when fertilizing, few people pay attention to supplementing trace elements, which hinders grape enlargement and thereby lowers the sugar content. Therefore, foliar fertilizer should be sprayed on the fruit trees in time to increase the trace element content in the trees.

3. Too much fruit

Many friends think when planting that the more fruit, the better, since it can increase yield. But too much fruit also requires more nutrients, and it usually exceeds the load the tree can bear. This leads to malnutrition: yield increases but fruit quality decreases, and no matter how much fruit there is, it is useless. Fruit trees should be thinned appropriately, and the number of fruits should be controlled within what the tree can bear, so that the fruits can develop better, accumulate more nutrients and improve in quality.

4. Fertilization

Fertilizing is a skilled job. Grapes need more nutrients to grow, so we also need to top-dress appropriately. However, many friends, in order to promote early ripening of the fruit trees and increase yield, apply too much nitrogen fertilizer, which causes the grape shoots to grow excessively and compete for the fruit's nutrients. This leads to a lack of nutrients and poor development. There must be a correct fertilization method, and the nutrient composition of the fertilizer must be reasonably blended to ensure it can provide all the various nutrients needed for grape growth.

5. Management

Field management of grapes is very important. Only by doing a good job of orchard management can the normal growth and development of grapes be ensured. Patrol the orchard frequently to discover various abnormal situations in time, do a good job of preventing various diseases and pests, and regularly carry out intertillage and disinfection in the orchard to reduce pathogens and lower the incidence of disease. Sort out the plants to enhance the orchard's air and light penetration, and appropriately pinch the growing tips and remove buds to prevent nutrient loss or nutrient dispersion. Create a good environment for the growth and development of the grapevines.

The above are the various causes of small grape berries. The main reason is still that everyone did not do a good job of orchard management when planting. They also did not pay much attention to disease prevention and control, and did not regularly carry out shaping and pruning of the plants, causing plant growth to be affected in various ways. This affects fruit quality. That is all for today's introduction. This article is for reference only, and I hope it is helpful to everyone.
