Better nutrient management strategy for rice-wheat, rice-rapeseed and rice-rice cropping systems

Rice-upland crop rotation is one of the most important cropping systems in China. To increase fertilization efficiency in these rotations, improve farmland soil fertility and reduce the risk of non-point pollution in the Yangtze river valley of China, carried out by the project cooperators in Wuhan Botanical Garden of CAS, the MOA of China and IPNI China program supported this research project in Hubei, Anhui and Hunan provinces since 2015.

The agricultural regions of China under rice-upland crop rotations are important for grain crop production, commercial fertilizer use, and ecological sustainability. Therefore, research on the technology and strategies of better crop fertilization in this region are important to help achieve the goal of optimizing fertilizer use to increase fertilizer use efficiency in the country.

Interpretive Summary

The agricultural regions of China under rice-upland crop rotations are important for grain crop production, commercial fertilizer use, and ecological sustainability. Therefore, research on the technology and strategies of better crop fertilization in this region are important to help achieve the goal of optimizing fertilizer use to increase fertilizer use efficiency in the country.

In 2016, supported by the government and IPNI China program, project cooperators in Wuhan Botanical Garden collected and summarized 101 field experimental results from rice-maize, rice-wheat, and rice-rapeseed crop rotation systems, which came from 54 experimental sites in six provinces of Yangtze River Valley.

Rice-wheat, rice-rapeseed, and rice-rice cropping systems are dominant in central China (Yangtze River Valley region). This region is one of the main grain crop production areas in China, with large amounts of commercial fertilizer consumption, but also fairly low fertilizer use efficiency.
