摘要
水稻采用垄作覆盖免耕免灌技术，能改善和保持良好的土壤结构，大量储蓄利用天然降水，避免水的流失，达到保持水土的目的，同时也是解决旱地灌溉、改造两用田，实现省水、省肥、省工的一套实用耕作技术。
With the agrotechnique of till-less, ridge and covering culture in arid farming field,the rice can become exempt from irrigation and yield well. Through this cultivation technique,a good soil structure can be formed and maitained . Sothat a great deal of natural precipitation can be efficiently conserved and utilized,which prevents loss of water and erosion of soil. It is showed that this farming technique is available in irrigation of dry farmland and transformation of dual-purpose field,so as to save water,manure and labour.
