摘要
八十年代中期以来，在川西平原和川西北丘陵，以小麦高产高效简化栽培为目标，从耕作、播种、施肥等主要方面研究了其简化技术、产量效应、增产原因和经济效益。在单项技术试验研究的基础上，采用少免耕、精量机点播、简化高效施肥三项关键技术，结合选用优质高产新品种、化学除草和机械化收获等措施，形成了小麦高产简化栽培技术体系，使产量、经济效益和劳动生产率均有提高，大面积示范推广取得了显著社会、经济效益。因此，研究和推广主要农作物的高产高效简化栽培技术，是提高种植业经济效益、发展高产优质高效农业的重要途径之一。
The high yield,high efficiency and simplified cultivation(HYHESC) of wheat were studied in Chengdu plain and northwestern hilly land of Sichuan Province in mid-eighties.The simplified cultivation techniques and their reasons for improving yield and economic effect were analysed from three aspects including tillage,sowing and fertilization etc.Based on the results of research on key factors,a HYHESC technical system involving light tillage or non-tillage,intensive drilling with a small dibbling machine and simplified fertilization method was set up. Both yield and economic benefit were promoted,the cultivating techniques of wheat were also simplified significantly with this technique system.
