What is the serious problem of tomato cracking fruit? Tomato cracking is a common physiological phenomenon. The main cause of fruit cracking is water imbalance, which is also related to the variety. 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.
There is a cone fruit. This situation is mainly caused by low temperature and phosphorus deficiency during the process of seedling cultivation. We all know that there is an important management measure in the process of tomato planting, which is to use the flower, and the flower should be determined according to the temperature of the outside world. The concentration of the syrup can not be used, otherwise the deformed fruit will appear. If the temperature exceeds 28 ° C, you need to weigh a certain amount of water, the higher the temperature, the more water, so as to ensure the normal results of tomatoes.
Ring cracks appear around the fruit, accompanied by leaf rolling, which is mainly caused by the excessive use of nitrogen fertilizer in the late growth stage of tomatoes, commonly known as calcium fat skin. The solution to this problem is to spray the nitrate fertilizer at the time of the two spikes of the tomato, and the time is generally between 8 and 10 am.
Measures to prevent 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 dry 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, and the transpiration of excess water in the plants is strengthened to prevent direct sunlight.
The fifth is to harvest tomatoes in time before the heavy rain.
