How to save tomato wilting? different treatment methods are used in different situations.

Strong sunlight: when the temperature is higher than 35 ℃, the leaves will wilt due to water evaporation, and the temperature should be controlled below 28 ℃. Improper watering: when the soil is short of water or the water temperature is higher than the ground temperature, the plant will wilt and need to be watered before 9 o'clock in the morning. Root damage: because the root system is shallow, it is easy to wilt the plant, so it is necessary to use rooting agent in time to strengthen the root. Weather reason: after the continuous low temperature in winter, a sudden rise in temperature will lead to wilting, do not suddenly pull the shed.

First, the sun is strong

1. Performance

The main results are as follows: (1) if the light at noon is too strong, and the temperature in the greenhouse is higher than 35 ℃, it will lead to strong water evaporation and wilting of tomato leaves.

(2) if the water absorbed by the root system from the soil can not meet the needs of tomato transpiration, the tomato plant will wilt, and if the situation is serious, the leaf edge of the tomato will be burned.

2. Solution

For tomato wilting caused by high temperature, vegetable farmers should keep ventilation at all times and control the temperature in the shed below 28 ℃, which can effectively avoid the wilting phenomenon caused by strong sunlight.

Second, improper watering

1. Performance

(1) the first is the wilting of tomatoes caused by lack of water in the soil, which can be solved after watering.

(2) the second is because the temperature is relatively low when watering, while the ground temperature is relatively high, which will lead to tomato capillary root injury, insufficient water absorption, resulting in tomato wilting.

2. Solution

(1) for the wilting of plants caused by improper watering, vegetable farmers should pay attention to watering the curtains as soon as they are pulled up in the morning, or to close the grass curtains immediately after watering, so as to avoid watering after 9 o'clock.

(2) when tomato wilted due to capillary root injury, vegetable farmers should apply rooting agent in time, or improve the soil temperature to promote the rapid recovery of capillary root, so as to alleviate the wilting condition of the plant.

Third, root system damage

1. Performance

If tomatoes are planted in winter, the tomatoes will be watered more and the roots will be shallower after planting. When the temperature drops, the root system of the plant will be damaged and wilted.

2. Solution

The main results are as follows: (1) due to the wilting of plants caused by root damage, it is necessary to properly control the water of tomatoes after planting, so as to promote the occurrence of roots, so as to increase the resistance of tomatoes.

(2) when watering, fertilizers containing amino acids and algins can be used to promote the development of roots.

Fourth, weather reasons

1. Performance

The main results are as follows: (1) the tomato in the greenhouse is in a stage of low temperature in winter. If you encounter low temperature or haze weather continuously, the light in the greenhouse will be relatively low, and the growth of the plant will be relatively weak.

(2) if the shed is pulled up suddenly after a sunny day, the light in the shed suddenly increases and the temperature rises faster, which will lead to water supply falling short of demand and wilting state.

2. Solution

When it is cloudy and rainy or when the sun is too strong, the roof of the greenhouse should be removed gradually and not all at once, otherwise it will cause great damage to the roots of tomatoes and even kill the plants.
