Need to pay attention to prevention and treatment of disease, because in the winter, the plant canopy because a long time in low temperature insulation was, chilling injury will greatly reduce the ability to grow vegetables, which reduces resistance, prone to Botrytis blight and other diseases. Therefore, early detection of disease farmers should be wire insulation, insulation timely prevention is price, when prevention is best to use aerosols or dusts control. Need to increase the effective light, farmers should first regular wipe for films, films improve the transmittance. Secondly, farmers also need to adjust the plant for the production of plants, removal of diseased leaves and old leaves of plants and improve plant performance between air and light. Then there should be in the back wall to add a reflective screen. Finally, note the time on a cloudy day without snow, the same should be waterproof or grass thatch insulation was opened because greenhouse-grown vegetables also need more scattered light, if the conditions can also add insulation was hanging lamp standards, because the use of Bulb plants can increase the rate of visible light can also raise the temperature inside the greenhouse. Waterlogging of low-lying land can not shed construction, you must first dig drainage ditches and then build greenhouses; the water table is too high, easy anti-pulp land, the soil must be multi-pad to greenhouse construction after heightening terrain. Otherwise, the ground temperature is low, excessive soil moisture, is not conducive to the crop root growth. Greenhouse construction site to be watered, convenient transportation, power supply equipment for management and product transport. The north-south orientation of greenhouse construction should be extended to the east and west side of the shed, then shed light distribution. The distance between the shed and the shed around, is shed 2/3 high. The distance between the two is too large shed, waste land, too close to the impact of the greenhouse effect translucent and airy, and films such as fixed job is not easy.
