Everyone who grows crops knows that if the soil moisture is too large, or if the relative humidity of the soil is not suitable for the growth of the crop, it will be easy to bring pests and diseases. So what should farmers do? Xiaobian introduces several methods to everyone.
What determines the soil moisture?
1 Determined by the number of soil irrigation or irrigation. The number of irrigation times is too high, and the amount of irrigation is large, which is undoubtedly the most direct increase in soil moisture.
2 is determined by the amount of evaporation on the ground. The soil moisture and the air humidity in the greenhouse interact with each other. This relationship is actually the law of conservation of matter. When the water in the space reaches a certain amount of saturation and cannot continue to increase the upper limit, energy migration occurs. And water is undoubtedly unable to escape such a law. Therefore, when the humidity of the air is large or small, the soil moisture will be small or large.
3 continuous rainfall will also increase the humidity of the soil.
Can try these few small measures!
1 high temperature weather, can enhance ventilation and ventilation, ventilation and dehumidification. However, it should be observed that if the temperature drops too fast, the vent should be closed in time to avoid freezing damage caused by low temperature.
2 control the rationality of watering. Watering is the main way we increase soil moisture, but if it is not well controlled, it will cause excessive humidity. After watering, appropriate air and loose soil can achieve the effect of reducing soil moisture.
3 Use lime, wheat straw and other materials to spread between the planting rows to absorb water.
4 Covering the mulch is also a common way of dehumidification. Covering the mulch film can reduce the evaporation of soil moisture, and can also reduce the indoor air humidity, which can be described as two things. After covering the mulch, it is possible to prevent the humidity of the air from increasing significantly after watering.
5 In the higher temperature weather, the temperature is increased to reduce the humidity by using a high temperature suffocating shed. But this method should pay attention to the fact that it is to be used according to the growth of crops. If the plant does not have enough growth, don't use it easily.
The problem about soil moisture is introduced here. The above methods hope that everyone can learn from it. Don't blindly copy it. The specific situation has to be adjusted according to different regions and climate.
