摘要
1986～1990年对水稻少免耕技术进行了多点系统调查和试验研究,认为免去耕耙作业即插秧的谓之免耕,减少耕耙程序、次数和降低能耗的谓之少耕。平原和丘陵稻区分免耕为撬窝型和板田直插型（含秧田和本田）;分少耕为以旋代耕型和半旱式垄作型,耕作方式间的增产效应趋势为:免耕稻>少耕稻>传统耕作稻。免耕类型的增产趋势是:撬窝型>直插型（秧田直插优于本田直插）。少耕类型的增产趋势是:垄作型>以旋代耕型。因地制宜地采用适宜的少免耕技术,均能增产节支。一般增产2～5％,省工2.7～4.7个,节油1公升,节支27～45元。
In 1986-1989, a systemic investigation and study of lo-and no-tillage technique of Paddy rice had been conducted. In this paper, the term of 'lo-tillage' that indicated to reduce the tilling and hacking Processes, times and energy comsume, the no-tillage indicated that the seedling transplanting carry out under without tilling and hacking works. In the rice area of plain and hilly land, the no-tillage forms, divided into dibbling and non-tilling, the 1o-tillage forms divided into ploughing replaced by gyrotilling and semiarid mound planting. The results of this study showed that all lo-and no-tillage presented yield increase as compared with the traditional farming. The trendency of yield effect of rice among tilling forms was no-tillage>1o-tillage>traditional farming. That among no-tillage forms was semiarid mound planting (increased by 13.4%) >dibbling transplanting (increased by 5.7-9.4%) >seedling transplanting in non-tilling (increased by 5.4-5.6%)>ploughing replaced by gyrotilling (increased by 3.3-5.4%) . The increase effects were significant, it's expanded prospects will be wild.
