1. For the timely replacement of damaged bamboo because bamboo thatch grass to bear the weight, in the face of heavy snow, bamboo will increase by gravity, causing part of the film prop split bamboo is pressed or crushed. 2. To the front of the roof surface and the turning point, as far as possible rag mat, hoses, PVC pipe and other protective tools, rope and plastic film laminated to avoid direct contact. 3. Replace the time to grasp the plastic film. Now farmers are more than a partner of the plastic film to be replaced, we will be ready to replace the bamboo, insulation was ready to advance, and then the new plastic film in front of the shed a good stretch, the new plastic film covering on top. 4. For those of poor quality plastic film insulation was introduced, there are those old plastic film, building insulation in the winter time is, anti-fogging drip bad, prone to dew when leaked, causing the greenhouse air humidity, so far contributed to the prevention of disease. The need to maintain that temperature inside the greenhouse is the use, you should first keep grass thatch or dry is a greenhouse insulation. Secondly, it is time once the temperature inside the greenhouse below 6 degrees Celsius, it is necessary to use burning stove for heating. Need to effectively reduce the humidity inside the greenhouse, sudden cold weather in winter, the growth rate of plants usually relatively slow power plant root activity is relatively small, so small plants need water, so farmers should try not watering, if Watering should be in the film, then watering, do not pour the flood, but also chasing instant dressing fertilizer, and the concentration is lower. Electric insulation was widely St. agricultural machinery _ _ Hainan insulation is provided by Shouguang Agricultural Machinery Co., St. Canton. Shouguang City, Canton St. Agricultural Machinery Co., Ltd.
