Causes and Control methods of the latest Tomato Leaf Roll
Tomato is a common vegetable in our life, which tastes good, is rich in a variety of vitamins, is loved by people, and has a wide range of cultivation. However, the phenomenon of tomato leaf curling will be chosen when planting, which will affect the yield and quality of tomato, so what is the reason for tomato leaf curling? Let's take a look.
1. Root system damage
After the root system of tomato is damaged, its water absorption will decrease, which leads to the phenomenon of curled leaves and yellow leaves caused by lack of water, and there are two reasons for root damage. First, man-made damage, in farmers for their weeding or ploughing, the hoe is too deep, resulting in root damage, such a long time will cause curling leaves. Second, the application of immature organic fertilizer will emit a lot of heat during decomposition, which will make the ground temperature exceed the root system and block the door, resulting in root burn and leaf curling.
Control methods: when ploughing and weeding, we must pay attention to it, it should not be too deep, so as not to damage the root system. When applying organic fertilizer or farm manure, it must be applied after full maturity.
2. Lack of nutrition
Tomato needs to consume a lot of nutrients during its growth. if there is a lack of certain elements necessary for tomato growth in the soil, it will affect its growth, such as boron, manganese and other elements will lead to smaller tomato fruit. In addition, improper fertilization will also affect the fruit and leaves, such as partial application of nitrogen fertilizer, will affect the absorption of other elements, resulting in the phenomenon of leaf curling.
Control methods: fertilizing tomato should be carried out according to the nutrients needed in its growing period. During the period from planting to flowering, it is only necessary to eat humic acid fertilizer or microbial agent to promote root growth. When entering the flowering and fruiting stage, Danlin shares can be applied, and when the fruit is expanding, high potassium fertilizer can be applied.
3. High temperature and drought
When the temperature is too high, the transpiration of leaves is great, but the soil is dry, and the water absorbed by roots can not meet the needs of leaf transpiration, so the leaves reduce the evaporation of water for green, so they will choose to close the bubbles, so there is a phenomenon of leaf folding or curling.
Prevention and control methods: in the period of high temperature and drought, it is necessary to water in time to maintain the water demand of the plant, but it is not suitable to irrigate too much at one time. The principle of less watering and frequent watering can be adopted.
The above is the introduction of the reasons and control methods of tomato leaf curling. I hope it can help you. If you want to know more about it, please follow us.
