Several characteristics of greenhouse seedbeds
1. The main structure of the nursery greenhouse The main structure is the main part of the greenhouse. Its structure and form must be scientifically and reasonably designed according to the local climatic conditions and planting requirements, so as to provide the best growth environment for the growth and development of crops. The structural design meets the safety standards, and the structural load design of the greenhouse is the basis of the safety design. The load of the greenhouse mainly includes dead load, wind load, snow load, crop load, equipment load, maintenance load, etc. The load of the same type of greenhouse, such as wind and snow load, its safe value is closely related to the service life of the greenhouse structure. The value of the value should not only be scientific, but also economical and reasonable. At the same time, the surface treatment of the main structural materials and connecting parts must meet the requirements of high rust resistance and corrosion resistance. Therefore, the durability of greenhouses is an extremely important aspect of the basic functions of modern greenhouses.
2. Seedbed net covering material crop cultivation has strict requirements on light, and the greenhouse is a lighting building, and its light transmittance performance directly affects the formation of photosynthetic products of crops grown in the greenhouse and the temperature in the greenhouse, so the light transmittance The rate is one of the most basic indicators to evaluate the performance of the greenhouse. The light transmission performance is affected by the covering material, currently available covering materials include plastic film, glass, PC board, etc.
