稻田免耕油菜育苗是解决无苗床以及秋收秋种劳畜力紧张矛盾的方法,为保证油菜不失时机培育壮苗移栽,为高产打下基础。一、结构特点实践证明,免耕育苗适应油菜生长发育的生理特性,稻田免耕田土含水量大且板结,因表土系翻上来的沟土,故松软肥沃,增施肥料不易渗透流失。油菜播后扎根发芽时,就能及时吸收大量养料,出苗 No-tillage rapeseed nursery paddy seedling is to solve the seedless autumn and fall harvest labor tension contradiction method, to ensure that rapeseed seized the opportunity to cultivate strong seedling transplanting, lay the foundation for high yield. First, the structural characteristics of Practice has proved that no tillage seedlings to adapt to the physiological characteristics of rape growth and development, paddy field no-tillage soil moisture content and compaction, because the topsoil turned up the ditch soil, it is soft and fertile, fertilizer is not easy to infiltrate. Rape sowing after germination, it can absorb a large number of nutrients in a timely manner, emergence
