Taoyuan County is a large grain and rapeseed production county. Taking advantage of the resource advantage of soil rich in selenium in Taoyuan County [1], it promotes high-yield cultivation and assembly technology of selenium-rich rice and rapeseed rotation in one-season rice area, optimizing the aggregate structure of the soil, improving the soil ecology and reducing the content of heavy metals in the soil [2], laying the foundation for the continuous increase in agricultural efficiency and farmers' income. Through rice and rapeseed rotation, the overwintering base of rice field borers are reduced, and the incidence of pests and diseases in the coming year is effectively reduced [3]. The implementation of supporting technologies for rice-rapeseed rotation cropping and the widespread promotion of high-quality varieties and planting techniques have improved the level of farmers’ planting. After one season of rice harvesting, most of the farmland is left unused. Using winter fallow fields to develop selenium-enriched rapeseed industry can actually increase the income of farmers.
