Study on “Three Controls,Two Preventions and One Simplification”Cultivation Technique for Interplanted Rapeseed in Double-cropping Rice Field

Aiming at the currentsituation of rapeseed cultivation in rice-rice-rapeseed system in Jiangxi province,according to the experimental researches for many years,we proposed three controls,two preventions and one simplificationcultivation technique for interplanting rapeseed in double-cropping rice field,namely: controlling oil-rice symbiotic period,stubble height of mechanically-harvested rice,and field moisture around rapeseed sowing; preventing weeds,and diseases and insect pests; simplifying fertilization. Thiscultivation technique was suitable for application in Jiangxi.
