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 %。
From 1994 to 1999, the comparative research and production demonstration on the cultivation methods of rice stubble in Sichuan Province showed that the technology of wheat precision clove-planting straw covering cultivation developed on the basis of small-density planting and no- Heat preservation, humidity control, improvement and soil fertility control, weed suppression and cost-saving and yield-increasing effects, achieving the organic combination of high yield, simplicity and high efficiency, high season yield and sustainable development of paddy fields. Than the general rotary cultivator sowing cost savings of 21.6%, an increase of 0.1%, saving 23.1%, an increase of 34.4%; than the pilot sowing on-site training 52.7%, an increase of 3. 9%, the section of 20.2%, an increase of 10.2%.
