Ridge tillage is a kind of conservation tillage for water harvesting and drought resistance,which is used widely in the rainfed cropland of the semi-arid sandy areas.
垄作是沙区旱作农田常用的集水抗旱耕作技术。
The paper, under the background of soil erosion paid extensive attention by the whole world and in light of the actual situation of China,expounds the necessity for soil erosion in the north rainfed farmland.
本文在土壤风蚀倍受国际社会广泛关注的背景下，结合我国面临的实际情况，阐述了在北方旱作农田开展土壤风蚀研究的必要性。
In order to release the severe water shortage for summer crops, ridge building method is used to harvest water on the dryland field without run off in semi arid areas of South Ningxia.
针对宁南半干旱偏旱区旱作农田夏熟作物所需水分严重缺乏的实情，在平整不产流农田上，通过沟垄径液集水蓄墒措施，在干旱年份中每年可向作物种植区增加水分供应５７。
