Reasons for upgrading and reconstruction of simple sheds

1. Compared with modern greenhouses, traditional greenhouses are relatively simple, and are widely used in economically backward periods because of their low material cost and convenient access.

2. However, due to the problems of poor thermal insulation ability, poor compression resistance and poor ventilation ability, sowing and planting, fruit and vegetable pollination, plant irrigation and fertilization, and fruit and vegetable harvesting all require a lot of manpower and material resources, and the production efficiency is low.

3, unable to meet people's production needs in time, coupled with the emergence of new materials in the later period, the emergence of modern greenhouses has become inevitable.
