The summer temperature is high, not only the air temperature, but also the ground temperature. During the day, the light enters the shed and shines on the surface of the soil, and the heat is then conducted into the soil, stored, and then released at night, resulting in a difficult night temperature. Therefore, in summer, while trying to find ways to reduce the temperature, we should also pay attention to appropriately lowering the ground temperature.
Watering to lower the ground temperature. Under the current conditions, the best way to lower the ground temperature is to water to cool down. When watering, pay attention to the method of combining large water and small water. Especially for newly planted seedlings, it is particularly important, large water can promote hair roots, small water wet soil can cool down. In summer, spraying water 1-2 times during the day can effectively reduce the ground temperature and temperature, and ensure the normal growth of vegetable roots.
The operation row lays straw to reduce the ground temperature. Covering a layer of straw or rice husk in the operation row of the shed is equivalent to laying a "mat" on the soil, preventing direct sunlight and making the soil temperature below the straw low, which is a very effective measure to reduce ground temperature. Before laying straw, vegetable farmers can first water a small amount of water to thoroughly moisten the soil, and then spread the straw, which can not only reduce water evaporation, maintain soil moisture, but also reduce heat storage.
Reasonable pruning and leaf picking, blocking strong sunlight. Reasonable thinning of branches and leaves can block strong sunlight and reduce ground temperature. It is recommended that vegetable farmers thin the diseased leaves, and it is better not to remove the other leaves, because these lower leaves can not only block the strong light from irradiating the ground, prevent the ground temperature from rising rapidly, and avoid excessive heat dissipation at night, but also increase the photosynthetic area.
How to reduce the ground temperature in the summer greenhouse is introduced here, I hope it will be helpful to everyone.
