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。
Aiming at the problem of tight crop rotation, uneven nutrient balance, serious pests and diseases and low production efficiency, the low-latitude rice-rape crop rotation and rotation in the low latitude plateau at Jintou Town, Tengchong City, was selected according to local conditions. Tillage and transplanting, comprehensive prevention and control of pests and diseases without transplanting rapeseed high yield and high efficiency cultivation techniques to achieve an average yield of 6.67 hm2 2937 kg / hm2 contiguous yield, output value reached 13 216.5 yuan / hm2, the production efficiency of 9346.5 yuan / hm2 , Respectively, than non-demonstration area and the city’s rapeseed production efficiency 1.19 times and 2.01 times.
