稻茬麦免耕栽培技术浅析

本文综合分析了雅安地区两大类型区稻茬麦克耕栽培技术．大渡河流域免耕比翻耕小麦每公顷增产604．5kg，增长11．2％，增收节支1850．10元．青衣江流域实现了改冬闲烂泥田一年一季水稻为麦稻两熟，每公顷增收小麦3633kg,扣除新增投入后增收3875.4元．对稻茬小麦免耕栽培适宜区域和稻田类型，以及适时开沟排水作厢、增窝增苗、肥料的施用等技术关键作了论述．

STUDY ON RICE-WHEAT NON-THLLAGE PRODUCTION TECHNIQUE

The effect and the key techniaue of rice-wheat non-tillage production with two ecological types in Yaan district were studied via a three year model trial. By Using non tillage production, it conld increase wheat yield 604. 5 kg per Ha, more than tillage at 11. 2% , equal to increas ineom 1850. 1 Yuan RMB in Dadu River Basin. In Qingyi River Basin, it could erop additional wheat with nontillage, obtain yield 3633kg per Ha, incretse income 3875. 4 Yuan RMB. The appropriate regions and field coditions of rice-wheat non -tillage, the technque about the optimum time to dig trenches for drainage and make bed, increasing holes, sedlings and fertilizer applicatin were diseussed in this yaper.
