The development of Greenhouse construction has been somewhat haphazard, mainly in two aspects: first, there is a lack of focus on expanding the area of solar greenhouses, resulting in wasted funds and low efficiency; second, there is a convergence in the types, structures, and applications of solar greenhouses.
Currently, the development of solar greenhouses should be based on stable area, increasing their internal capacity, and moving towards higher efficiency.
Suitable greenhouse types, structures, and supporting equipment should be selected according to their intended use. That is, solar greenhouses of different sizes, specifications, and grades should be built according to their purpose and production needs, striving for economy, modernization, and high efficiency.
Sawtooth Greenhouse have a weaker ability to withstand natural disasters and adversity. Problems in winter fruit and vegetable production include the effects of sub-zero temperatures, chilling injury, and frost damage, while indoor temperatures are too high in summer.
This not only reduces the yield and quality of vegetables but also affects the stability of production. The countermeasures for Sawtooth Greenhouse are: solar greenhouses should have fixed or temporary heating equipment throughout the year, and cooling measures should be implemented in summer.
Another type of disaster is the damage caused by pests and diseases. Modern integrated pest management technologies are needed, with prevention as the primary focus, and strengthened monitoring to minimize the impact of pests and diseases.
In terms of pest and disease control, we need to shift from a dual control approach of prevention and yield protection to a three-pronged approach of control (control, production, and pollution).
