Tomato green skin prevention should pay attention to the following points:
Adding organic fertilizer: using formula fertilization technology, it is not advisable to use ammonium fertilizer to adjust the ratio of nitrogen, phosphorus and potassium in the soil. Spraying light film fertilizer at seedling stage can help the growing plants absorb light energy and improve fertilizer efficiency. This is the most important measure to prevent tomato green fruit.
To extend the light-seeking time of vegetables: When the fruit enters the color-changing period, the lower leaves and nearby leaves of the color-changing ear should be removed, and the increase of light can reduce the occurrence of green fruit.
Roots and roots are enhanced to enhance plant resistance: foliar fertilizers containing various elements (boron, calcium, magnesium, iron, zinc) are used on the foliage, and the roots of the roots and the roots are combined with the “micro-fertilizer†to fill the roots. Inducing plants to absorb, digest and release nitrogen, phosphorus, potassium and various trace elements in the soil, improve the positive energy of fruit development, optimize fruit quality, and reduce green skin and cracked fruit.
Strictly control the temperature: the daytime temperature should be controlled at 25 °C ~ 30 °C, the night temperature should be maintained at 14 °C ~ 16 °C, the temperature difference between day and night should not exceed 15 °C.
