针对重庆市油菜种植中的制约因素,开展了稻-油机械化轻简生产技术模式研究。该技术模式适用于重庆海拔200~800 m的浅丘平坝和中丘低山区,在前茬水稻稻田放水机收后,抢在9月20日—10月20日的阴天或者下雨前,采用免耕或者浅耕机械直播油菜种子,实现稻-油连作的机械化轻松、简略生产,从而极大地降低劳动力成本,提高油菜生产效益。该技术模式的核心是播种轻简、增窝加密、控氮增磷钾,早施苗肥,促苗压草,实现以数量换产量、以效率换效益的目标。
Aiming at the restricted factors of rapeseed cultivation in Chongqing, the research on the technical mode of rice-oil mechanization and light-weight production was carried out. The technical model is suitable for Chongqing shallow elevation of 200 ~ 800 m of Pingba and mid-hill low mountain area, in the former crop of rice paddy water collection machine, grab in the September 20 -20 cloudy on the 20th or before the rain, No-tillage or shallow tillage machinery direct rapeseed seeds, rice-oil continuous crop mechanization and easy, simple production, thus greatly reducing labor costs and improve rape production efficiency. The core of this technology model is sowing light and simple, increasing nest encryption, nitrogen and phosphorus increased potassium, early Miao Miao, Miao Miancao to achieve the number of output, efficiency for efficiency goals.
