Reducing the humidity of vegetables in winter greenhouses in five aspects
First, the use of non-drip film. The use of non-drop film can reduce the amount of water on the surface of the film, and is conducive to light transmission and temperature increase in the booth. The second is to cover the film. Because the film is airtight, it can reduce ground water evaporation and irrigation times, so as to achieve the purpose of reducing air humidity in the shed. The third is reasonable watering. Watering vegetables in winter, to achieve "five-five no pouring," that is, sunny watering, cloudy, not watering; before noon watering, no water in the afternoon; pouring small water, not flood irrigation; pouring warm water, not Pouring cold water; pouring dark water, not pouring water. The fourth is to improve the method of application. In the winter greenhouses, vegetable pests should be treated with smoke or dust as much as possible. If the spraying method is used, the frequency of control and spray volume should be appropriately reduced to prevent the humidity in the greenhouse from being too high and affect the growth of vegetables. The fifth is artificial moisture absorption. If the humidity in the shed is too high, some straw, ash or fine dry soil can be sprinkled between the rows, or hygroscopic materials such as quick lime can be placed in the shed to absorb moisture.
