In the production of the agricultural greenhouse, keeping the temperature in the shed is the basic condition to keep the crops growing well.
Generally speaking, the temperature inside the shed can vary with the temperature outside. The change rule is, the higher the temperature outside the shed, the greater the temperature value inside the shed, and the lower the temperature outside the shed, the smaller the value-added inside the shed. In general, the maximum and minimum temperatures in the shed occur about two hours later than on land.
The temperature in the shed often varies with the weather and the seasons. Users can add a series of protective measures according to the change of greenhouse temperature to keep the temperature constant. The temperature difference is larger on sunny days and smaller on rainy days. The lower the temperature, the higher the daily temperature, and vice versa. In addition, users can also according to the early cultivation of vegetable varieties suitable growth temperature requirements to strengthen the temperature regulation in the shed.
At the same time, different crops have different temperature requirements. Users can adjust according to realistic conditions and crop requirements. For example, there is usually no ventilation before planting seedlings after transplanting. It is used to raise the temperature in the shed, which is conducive to the growth of crops. Not only that, but the user also according to the seasonal conditions for adjustment, early spring due to weak light, but the effect of temperature increase in the shed is also poor, can be used to cover plastic film and small arch shed measures, to improve the effect of heat preservation.
Here's how the greenhouse dehumidification problem can be solved by the planting greenhouse installation company: Water is the main factor leading to indoor humidity increase, so how to water has become an important measure to control the humidity. Winter and spring production can choose clear ditch water or water plants, dark irrigation under plastic film mulching film can be used. Water shall strictly control the water quantity, to prevent the indoor humidity is too high. The outer membrane well prevents the loss of carbon dioxide produced by internal vegetable growth, make the huts have a good heat preservation effect.
After each watering appropriate wind, timely mattock soil can reduce the soil moisture, also can reduce the air humidity. Water is the main factor leading to indoor humidity increase, so how to water has become an important measure to control the humidity. Winter and spring production can choose clear ditch water or water plants, dark irrigation under plastic film mulching film can be used. Water shall strictly control the water quantity, to prevent the indoor humidity is too high. After each watering proper lookout, in a timely manner HuaChu scarification, can reduce the soil moisture, can also reduce the humidity of the air. The greenhouse is one kind has excellent thermal insulation performance of the effect of the frame structure, it makes people can eat the anti-season vegetables. General greenhouses use bamboo structure or the steel structure of the skeleton, above a layer or multilayer insulation plastic compound, This creates a greenhouse space.
