Greenhouse construction must consider its durability, how to manage it correctly?
Greenhouse construction must consider its durability. Greenhouse durability is affected by factors such as the aging resistance of greenhouse materials and the bearing capacity of the main structure of the greenhouse. In addition to its own strength, the durability of light-transmitting materials is also manifested in that the light transmittance of the material decreases with time, and the degree of attenuation of light transmittance is a decisive factor affecting the service life of the light-transmitting material. Generally, the service life of steel structure greenhouse is more than 15 years. The design wind and snow loads are required to be used for 25-year once-in-a-lifetime loads; the bamboo-wood structure simple greenhouse has a service life of 5 to 10 years, and the design wind and snow loads are used for 15-year once-in-a-lifetime loads. Due to the long-term operation of the greenhouse in a high temperature and high humidity environment, the surface corrosion protection of components has become one of the important factors affecting the service life of the greenhouse. Steel structure greenhouse, the main structure of the force is generally made of thin-walled steel, which has poor corrosion resistance. In the greenhouse, it must be treated with hot-dip galvanized surface anti-corrosion treatment. life. For wooden structure or steel welded truss structure greenhouse, it must be ensured that the surface anti-corrosion treatment is carried out once a year.
Intelligent greenhouse construction refers to the thermal insulation construction that can provide growth period and increase yield in seasons that are not suitable for plant growth. The correct management of greenhouse construction should pay attention to the following three points:
1. The film should be removed in time. After the autumn vegetables are over, the greenhouse film should be removed in time to cool down. Some vegetable farmers replace the new film before the autumn tea vegetables are planted.
2. Fertilize and turn the ground early. It is recommended that vegetable farmers apply manure into the soil as soon as possible. After a period of decomposing, it can be converted into nutrients that can be directly absorbed and utilized by crops, which also eliminates the side effects of fertilizers and avoids burning roots and gas damage. Wait for the problem to appear.
3. To clean up the countryside, it is recommended to clean up the shed in time after the autumn tea vegetables are finished.
