Background

The greenhouse has wide application in vegetable production, for example, the greenhouse plays a role in heat preservation in vegetable planting in winter and spring, can avoid serious natural disasters from damaging planted crops, and lightens the investment risk of growers.

In winter and spring, the weather is mainly rainy days, and low temperature, poor illumination and high humidity prevail, in winter and spring greenhouse planting production, watering and spraying application of pesticide are two main factors which cause the humidity in the greenhouse to increase, and low temperature and high humidity cause the occurrence and spread of diseases of greenhouse crops, for example, the diseases of downy mildew, gray mold and the like of vegetables such as tomatoes, watermelons, melons and the like planted in the greenhouse in winter and spring are easy to occur in the low temperature and high humidity environment. Therefore, controlling the humidity in the greenhouse is one of the important links of the cultivation technology. The common method comprises the steps of ventilating and dispersing moisture, namely exchanging air containing a large amount of moisture in the greenhouse with dry air outside the greenhouse through ventilation to reduce the air humidity of the greenhouse, and has the defects that if the temperature outside the greenhouse is too low, a large amount of cold air enters the greenhouse, the temperature in the greenhouse drops suddenly, and crops are easily frozen in the ventilating process; and secondly, dehumidification equipment is installed, and a dehumidifier is installed in the greenhouse, so that the dehumidification effect can be achieved, the greenhouse construction cost is increased, and meanwhile, a large amount of electric energy is consumed by using the dehumidifier, so that the cost investment of farmers is increased.
