Use of its good lighting and thermal insulation properties, production in winter and spring, before the Spring Festival start listing.

With the gradual improvement of external environment, it is more suitable for the characteristics of legume temperature, suitable for the growth and development of legumes, with higher yield and better economic benefits . More suitable types, such as cowpea, beans, beans and so on.
