What is the reason for tomato cracking fruit?

Tomato planting cracks ž Reason:

1. The main cause of cracking in tomatoes is water imbalance, which is also related to varieties. Longitudinal cracks occur, and the common people are commonly known as pistachios. This situation has little to do with your ten or twenty years of development, and it has little to do with the variety you grow. It is a physiological disease that has a vital relationship with the base fertilizer and trace elements you apply. To solve this problem, it is necessary to apply organic fertilizer.

2. If the temperature exceeds 28 ° C, it is necessary to exchange a certain amount of water, the higher the temperature, the more water, so as to ensure the normal results of tomatoes. Otherwise, there will be a deformed fruit. 3. In the late stage of tomato growth, excessive use of nitrogen fertilizer will cause ring cracks around the pedicle, accompanied by leaf rolling.

What to do with tomato cracking:

The first is the variety selection. Choose varieties that are resistant to cracking, luxuriant foliage, thicker and more tough skin.

The second is to maintain a suitable soil dryness and humidity. Covered with mulch or covered with straw, maintain a relatively stable soil moisture and prevent dryness and humidity.

The third is to increase the application of organic fertilizer, improve soil structure, and improve soil water retention and fertilizer retention capacity.

Fourth, moderate pruning and topping ensure that the branches and leaves of the plants are luxuriant, strengthen the transpiration of excess water in the plants, and prevent direct sunlight from the fruits.

Fifth, pick up tomatoes in time before heavy rain.

Tomatoes are fertilized after fruit setting:

A potash fertilizer, tomato demand for potassium after fruit set, potassium fertilizer can effectively promote fruit enlargement without deformity caused by deficiency, etc., at this time, if you follow the previous topdressing method to reduce the absorption rate, the soil should be applied to the fertilizer After 5-7 days of conversion, the Z-fast method is to apply potassium fertilizer, and it can be absorbed and utilized in 5-7 days, thus directly feeding the fruit.

Two other trace elements, calcium, boron, manganese. Zinc. Trace elements such as molybdenum also have an important auxiliary effect on tomato results. It can be sprayed with rich nutrients and full-nutrient water-soluble fertilizer. Trace elements can enhance the resistance of tomatoes to common diseases, reduce the rate of inferior fruits, etc. Efficient supplementation with foliar spray is carried out along with the application of water-soluble fertilizer.
