The water is not suitable for the roots. Tomatoes are in the fruitful period, in order to ensure fruit growth, farmers in the management process should mainly control the amount of water, if the amount of fertilizer is too large for one-time watering, it is very easy to cause root damage, resulting in slow growth of capillary roots, after root injury The ability to absorb moisture will decrease. Reasonably watered. The temperature is too high and the transpiration of tomato leaves is strengthened. Watering should be carried out in time. If water is not timely watered at high temperature and drought, the stomata of the tomato leaves will close, and the phenomenon that the leaves start to roll up from the lower leaf will appear. Therefore, we must pay attention to reasonable fertilizer and water management, and keep the wet soil conditions. If the tomatoes appear curled, they should be sprayed with a new high-fat moisturizing film to reduce evaporation of leaf moisture and delay its aging.
