Fertilizer is not suitable for root injury. At present, the spring tomatoes are at the peak of the results. In order to ensure the fruit growth, many vegetable farmers have increased the amount of watering and fertilization. If the amount of one-time watering and fertilization is too large, it will easily cause root damage, resulting in slow growth of capillary roots. After root injury, the ability to absorb water will decrease, and the amount of root water absorption will be small, which will not meet the demand of transpiration. Tomato roll leaves.
The soil is short of water and drought. In the interview, I learned that many vegetable farmers have different days of watering. However, the current temperature is high, and the transpiration of tomato leaves is strengthened. If watering is not carried out in time, the stomata of tomato leaves will be under high temperature and drought conditions. When it is closed, there is a phenomenon that the blade rolls up from the lower blade.
Therefore, in order to prevent the rolling of tomatoes, it is necessary to pay attention to reasonable management of fertilizer and water, and to maintain the soil conditions of wet and dry. In addition, after the tomato has rolled leaves, it can promote the recovery of the leaves and delay the senescence.
Spraying cytokinin 400 times and adding nucleotide leaf fertilizer 500 times, the effect is better.
