The county of Zhongjiang in Sichuan is one of the main producing areas of the salvia miltiorrhiza in China, the cultivation history is long, the artificial cultivation of the salvia miltiorrhiza starts from the county of Zhongjiang in Sichuan, but the salvia miltiorrhiza is forbidden to be continuously cultivated, and the continuous cultivation causes the overground part of the salvia miltiorrhiza to grow short and small, the root system to grow weakly, the root inside to blacken, rot and malformation and the root to split. With the increase of the continuous cropping age of salvia miltiorrhiza, the problems of soil degradation such as soil acidification, salinization, soil hardening and the like are also caused. Moreover, the soil-borne diseases are serious, and the red sage root frequently has main diseases such as root rot, blight, red leaf disease, morbid diseases and the like. The growth of the next plant is directly damaged, so that the active ingredients of the plant are reduced, the appearance of the root system is deformed, the commodity rate is low, the quality of the salvia miltiorrhiza is seriously influenced, and the sustainable development of the salvia miltiorrhiza producing area is threatened.
The rotation of salvia miltiorrhiza and ginger is a rotation system commonly adopted in Zhongjiang county to prevent the occurrence of continuous cropping obstacles of salvia miltiorrhiza, the rotation mode is easy to implement, the survival rate of root segments of salvia miltiorrhiza is high, and the problem of soil degradation caused by continuous cropping of salvia miltiorrhiza can be relieved to a certain extent. However, the roots of the next-crop salvia miltiorrhiza planted after crop rotation are thin and short, and root-knot nematodes or root rot and the like still occur. In addition, the period of the rotation of the salvia miltiorrhiza and the ginger is long in fallow period, the land is idle, and the land resource is wasted.
