Some netizens and Xiaolin of Huinong.com reported that the tomato planted in their own home had a leaf-rolling situation. I don’t know what to do. So today, Kobayashi wants to tell you about the reasons and treatment of the tomato leaf, hope to provide a reference for everyone! The physiological leaf curl of tomato is often caused by water shortage in the leaves. So what are the reasons for the lack of water in the leaves? The tomato leaf is generally caused by the following three aspects: First, the roots are poorly developed or injured, and the water absorption capacity is weak, which makes the plants lack water. Second, the temperature is high and the soil drought causes the leaves to roll. When the temperature is high, the leaf water transpiration is large, the soil is dry, and the roots absorb water to meet the needs of leaf transpiration. Therefore, the leaves reduce the water transpiration and close the pores, causing the leaves to gather or curl. The third is caused by insufficient nutrition. The organic matter content in the soil is low, and the lack of essential elements will affect the growth of the plant. Especially when the fruit is sitting or starting to harvest the fruit, it needs a lot of nutrients. If the nutrition is not effectively supplied, the first fruit branch leaves will curl, or the whole plant will appear. The blade is cylindrical and brittle. For the above three reasons, it is recommended to do the following three steps: First, it is necessary to strengthen the maintenance of the root system after the tomato is planted. Appropriately apply some of the root-feeding functional fertilizers to enhance their root absorption capacity, such as chitin, 963 roots, or alginic acid, Jin Yinglai. The second is the high temperature season in summer, which strengthens the adjustment of greenhouse temperature and soil moisture. Use shade net cover to reduce the temperature of the greenhouse, dip the small water to control the soil moisture, and avoid the high temperature and water shortage caused by the coil. Third, the tomato growth period, especially after fruit setting, should be kept up to avoid the lack of fertilizer to cause the leaves to curl. Try not to choose inferior chemical fertilizers, because not only can the nutrition not reach the roots, so it is recommended to apply some quick-acting, high-utility compound fertilizers, such as Yinglaisheng Road, a large amount of elemental water soluble fertilizer, or US KOMU compound fertilizer. , or three gold peptides can be compound fertilizer.
