| 摘 要： | 2001～2003年在贵州中部Karst地区进行稻田节水灌溉技术试验和推广,试验区和示范区粳稻增产594kg hm2,节水3300m3 hm2,灌溉水分生产率(粳稻)平均为2 09kg m3,杂稻平均为2 42kg m3,分别是常规灌溉的1 23倍和1 21倍。经系统分析,得出Karst中部地区稻田节水高产的技术模式。

| Abstract: | A three-year investigation on paddy field water-saving irrigation in central karst area of Guizhou produced the results are as follows:in the experimental and demonstratal field,the rice yield increased by 594kg/hm~2;the water saving by 220m~3/acre;the average irrigation productivyty by 2.09kg/m~3;the hybrid rice yield by 2.42kg/m~3.Compared with these by normal irrigation,there was an increase of 1.23 and 1.21 times respectively.Therefore,a technical model is given through the systematic analysis. |
