The latest tomato green fruit control methods

Tomato green-skinned fruit is a kind of tendon rotten fruit, which is a physiological disease during the growing period of tomato. The occurrence of this disease brings great losses to farmers, so it is necessary to take corresponding control measures. so what is the cause of tomato green-skinned fruit? How should I treat it? Come and have a look with the editor.

First, the reason for the green fruit of tomato

There are many reasons for tomato green fruit, one of the most important reasons is unbalanced fertilization, too much nitrogen fertilizer, less potassium fertilizer, excessive application of nitrogen fertilizer and relatively less potassium is the main reason for the formation of tomato green fruit. In the tomato machine to the color conversion period, too high nitrogen in the plant will cause the nutrition level is too high and some to lycopene formation, fruit color conversion is not uniform, the formation of yellow fruit. Second, it is caused by varieties, from a genetic point of view, varieties that are resistant to storage and transportation have the phenomenon of green fruit in varying degrees; third, because of temperature, tomatoes will produce lycopene after entering the color conversion period, and the appropriate temperature is 10-25 degrees. If it is lower than 10 degrees or higher than 25 degrees, it will inhibit the formation of lycopene, so it will produce a large number of green fruits.

II. Prevention and control methods

The main results are as follows: 1. The most important measure to prevent tomato green fruit is to apply more organic fertilizer, adopt formula fertilization and use less ammonium fertilizer, so as to adjust the ratio of nitrogen, phosphorus and potassium in soil and promote the absorption and utilization of potassium fertilizer.

2. After the fruit enters the color conversion period, it is necessary to remove the lower leaves and nearby leaves of the color-changed ear, and increasing light can reduce the occurrence of green fruit.

3. Boron, calcium, magnesium, iron, zinc and other trace elements can be supplemented to the plant by foliar fertilizer, in which the amino acid type is suitable, which can make the leaves black and green, enhance photosynthesis, increase the absorption of boron and calcium, and reduce green bark and fruit cracking.

4. the temperature should be controlled strictly, between 25-30 degrees during the day and 14-16 degrees at night. Note that the temperature should not exceed 15 degrees during the day and night.

5. To balance the fruit-setting number of the plant, the fruit-setting part is too much or the fruit-setting position is too low, and the fruits with too much fruit-setting and too low fruit-setting position should be removed in time.

6. it is necessary to control the concentration of flower hormone, not too high, and replenish fertilizer in time after using anther and flower.
