摘要
1994～ 1 999年 ,对四川稻茬麦的种植方式进行比较研究和生产示范表明 ,在小窝密植技术和免少耕技术基础上发展起来的小麦精量露播稻草覆盖栽培技术 ,具有明显的保温、调湿、改良和培肥土壤、抑制杂草和节本增产增收效应 ,实现了高产与简化高效、当季高产与稻田持续发展的有机结合。一般比旋耕机播栽培节约成本 2 1 .6% ,增产 1 0 .1 % ,省工 2 3 .1 % ,增收 3 5.4 % ;比撬窝点播栽培省工 52 .7% ,增产 3 .9% ,节本 2 0 .2 % ,增收 1 0 .2 %。
In 1994~1999 experiments and field demonstrations were conducted to test the effect of cultivation patterns on grain yield and benefit of wheat. The results showed that the new cultivation technique of surface seeding and mulching rice straw under zero tillage greatly increased grain yield and planting benefit by reducing labor and material cost. In addition, this cultivation pattern could effectively fertile soil and improve ecological environment.
