摘　　要：冲压机械密实土壤灌溉节水新技术是适用于沙土、高沙土等渗漏量较大地区的水稻灌溉节水新技术,该技术利用冲击压实机对土壤实施压力,压实水稻田耕作层以下土体,既可以起到节水的效果,又能达到保持土壤肥力、改善水稻生长所需的营养条件、促进水稻增产的目的,同时还具有减少地下水污染的作用,具有显著的经济、社会和环境效益。Compacted soil irrigation with punching machines is a new technology that suits for paddy field located in sandy soil and high sandy soil with relatively big percolation. Impact compaction machine is used for compacting soil under the cultivation layer, which can not only conserve water but also soil fertility and nutrients needed by rice plantation. It has obviously economic, social and environmental benefits through increasing rice production and reducting groundwater pollution.
