How to realize temperature management in greenhouse

In the production of greenhouses, maintaining the temperature in the greenhouse is a basic condition for maintaining good crop growth.

Generally speaking, the temperature in the shed can change with the change of outside temperature. The law of change is that the higher the temperature outside the shed, the greater the temperature increase in the shed, and the lower the temperature outside the shed, the smaller the value in the shed. In general, the highest and lowest temperatures in the shed occur about 2 hours later than the open field.

The temperature inside the shed often changes with the weather and the seasons. When using the user, the user can add a series of protective measures according to the change law of the temperature of the greenhouse to keep the temperature in the shed constant. On a sunny day, the temperature difference is large, and the temperature difference between rainy and sunny days is small. The lower the temperature, the higher the daily temperature, and vice versa. In addition, the user can also strengthen the temperature adjustment in the shed according to the suitable growth temperature requirements of the early mature vegetable varieties.

At the same time, different crops have different temperature requirements. Users can adjust according to actual conditions and crop requirements. For example, it is generally not ventilated before the seedlings are planted, so as to improve the temperature and temperature in the shed, which is conducive to the growth of crops. Not only that, but users also need to adjust according to the seasonal conditions. In early spring, due to weak light, the effect of warming in the shed is poor. The mulch and small arch shed measures can be used in the greenhouse to improve the temperature and heat preservation effect.
