摘　　要：针对以腾冲市界头镇为代表的低纬高原水稻—油菜水旱轮作茬口紧张、养分不平衡、病虫害严重、生产效益低的问题,因地制宜选择品种、建立扣种稀植培育幼壮苗、免耕移栽、综合防控病虫害的稻后油菜免耕移栽高产高效栽培技术,实现6.67 hm2平均产量2937 kg/hm2的连片高产,产值达到13 216.5元/hm2,生产效益达到9346.5元/hm2,比非示范区和全市油菜生产分别增效1.19倍和2.01倍。To settle series of problems in rice- rapeseed rotation system of low latitude plateau,including seasonal stress,nutrient imbalance,serious diseases and pests and low production benefit,high- efficiency cultivation techniques based on no-tillage transplanting for rapeseed after rice were established,and the key techniques included choosing varieties according to local conditions,breeding high quality seedlings,no tillage transplanting,comprehensive prevention and control of diseases and pests. Field experiment and demonstration showed that the average yield of rapeseed reached to 2937 kg / hm2 on an area of 6. 67 hm2,the output value reached to 13216. 5 yuan/hm2,and the production benefit reached to 9346. 5yuan / hm2 which was 1. 19 and 2. 01 times of that of rapeseed production in the non- demonstration region and whole Tengchong city,respectively.
