Autumn 茬 tomato is generally planted in large area in August, but in order to catch the high price in the early morning market, many vegetable farmers will plant the planting time until mid-July. However, the high temperature and drought in the early stage have adversely affected the growth of tomato. Cracked fruit and exposed seeds.

The umbilical part of the tomato is a physiological disorder and a kind of deformed fruit. So what is the cause of tomato malformation? The root cause is that the flower buds are poorly differentiated in the early stage, and the deformed flowers are formed. The fruits of the deformed flowers are all deformed fruits.

The characteristics of the variety are the basis for determining the development of tomato flower and fruit. On the basis of selecting the varieties, the vegetable farmers should also grasp the following three aspects:

Regulate the shed environment

The main factors affecting the flower and fruit malformation of autumn oak are temperature and light. At present, there are many high temperature and strong light weathers, which are easy to cause high temperature obstacles and strong light in tomato, and it is easy to cause the seedlings to grow long, the flower buds are poorly differentiated, and the flower and fruit deformity rate is high.

Coordinate the relationship between vegetative growth and reproductive growth

Autumn sorghum tomatoes generally leave six ears or seven spikes of fruit. From the beginning of fruit setting to the end of fruit set, it is the time when fruit and stalk grow at the same time. Tomato is a continuous flowering and continuous crop. When the first inflorescence fruit grows, the second, third, fourth and fifth inflorescences develop to varying degrees, especially in the 20 days after flowering, a large amount of carbohydrates are transported into the fruit. Between vegetative growth and reproductive growth, as well as between fruit development and flower bud differentiation, competition for nutrients is more obvious. Once the nutrient supply is insufficient, it will affect the development of several spikes. Therefore, after the tomato enters the fruit setting period, it should be based on high-potassium fertilizer. It can be applied twice to high-potassium fertilizer and a balanced fertilizer to promote the fruit.

Foliar supplementation, calcium supplementation

Boron fertilizer is beneficial to plant flower bud differentiation, and calcium fertilizer can improve the toughness of pericarp cells and reduce the occurrence of cracked fruit. Therefore, the vegetable grower can spray borax 600 times liquid or speed borax 1500 times liquid mixed with high quality calcium fertilizer to promote the normal growth of the fruit setting and fruit of the tomato.
