On April 26, in the tomato greenhouse of Yang Suhua of Gucheng Street, she anxiously asked the reporter: “Look! The lower leaves of my whole shed persimmon are curled, and the fruit is not long. What do you think is this matter? How to adjust the adjustment, you can die me!" After the rolling of tomato leaves, the photosynthetic activity cannot be carried out normally, resulting in insufficient supply of photosynthetic products and insufficient nutrition of the fruits, thus manifesting as small fruits, slow growth rate, and many malformed fruits, which seriously affect the yield and quality of the tomato. For the reason of curling, the reporter believes that it is caused by water shortage. Because tomatoes are prone to prosperous growth in the early stage, many people like to use water control measures to control the tomato's leggy. As a result, under conditions of high temperature and drought, the transpiration of leaves is greater than the moisture supplied by the roots, and the tomato leaves protect themselves and close the stomata. At the same time, the vegetable farmers are afraid that the plants are prosperous. Usually the watering is not timely, which results in insufficient supply of water absorbed by the roots, which causes the tomato leaves to roll upwards from the lower leaves and roll up into a tube when serious. Thus further manifested as the occurrence of small fruit and slow fruit growth. How to solve it? First, spray on the foliage. According to the characteristics of fast water absorption by the leaves, the leaf is sprayed with water in time to supplement the water needed for tomato growth. At the same time, in order to avoid excessive transpiration of water, you can add a little white sugar in the water, so as not only to increase the adhesiveness of medicines and fertilizers, but also to form a protective film on the leaves after spraying to reduce the transpiration of water. Second, a reasonable watering. Reasonable watering after tomato leaf rolling can effectively relieve symptoms, the first water after leaf rolling can not be flooded with water, and a small ditch should be poured to pour water, and the water can flow to the other end of the crucible. Avoid water and roots, so that not only can not solve the problem of water shortage, but also cause root damage, so that the yellow leaves of tomatoes; second water can be timely watering according to production needs, can increase the amount of water. Second, it cannot carry fertilizers, especially chemical fertilizers, to prevent fertilizers from damaging roots. In order to avoid fruit growth and slow growth, it is possible to replenish the fertilizer in the second water, and the second water can be watered for 3-4 days after the first water.
