The phenomenon of green skin in tomatoes is often absorbed, and the most effective way to prevent green skin from tomato is to apply organic fertilizer. We can adopt the technology of formulating fertilizer application, and it is not suitable for applying ammonium fertilizer too much, so as to reasonably adjust the proportion of nitrogen, phosphorus and potassium in the soil, and enhance the complete absorption and effective utilization of potassium by plants. It is the most critical way to avoid tomato green fruit.
First, increase the time that vegetables can illuminate light. When the tomato enters the color-changing period, it is necessary to clean out the lower leaves of the color-changing ear and the surrounding leaves, and enhance the illumination time to avoid the occurrence of green fruit.
Second, the roots are strong and need to be rooted, so that the plant resistance is enhanced. Foliar fertilizer containing various elements such as calcium, iron, magnesium, boron, zinc, etc. is needed on the leaf surface, and the amino acid type is most suitable here, which can promote the leaf black and green, enhance the photosynthesis, and enhance the boron and calcium elements. The amount of absorption, so as to avoid the phenomenon of green skin, cracked fruit and so on.
Third, it is necessary to strictly control the temperature. In the daytime, it is necessary to control the temperature at 25 ° C - 30 ° C. At night, it is necessary to maintain the temperature at about 14 ° C - 16 ° C to ensure that the temperature difference of daylight night is not allowed to exceed 15 ° C.
Fourth, to balance the number of fruit set in the plant, it is not allowed to take too much fruit and the fruit setting is too low.
Fifth, you need to control the concentration of the flower hormone, not too high, you need to immediately add fertilizer after using the anther flower.
Sixth, for those greenhouses that have already appeared green fruit, you can choose to spray high-potassium foliar fertilizer, chitin, etc. to control the green peel. After that, we need to find a scientific and reasonable solution to the tomatoes that have already appeared green skin.
