| 摘 要： | 目的]为缓解贵州省农田灌溉水资源紧张的状况,达到水资源有效利用与优化配置,通过进行连续的水稻节水灌溉试验,总结适宜贵州省水稻灌溉的模式.方法]采用科灌、科蓄及普灌3种灌溉方式进行试验,分析了不同灌溉处理对水稻农艺性状、灌溉水量、水分生产率的影响.结果]科蓄模式下净灌溉定额最少(3979.50 m3/hm2)、水稻产量最高(9024.00 kg/hm2)、灌溉水分生产效率最高(3.28 kg/m3),其综合效果明显优于其他2种灌溉模式.结论]科蓄模式适合贵州省农业耕作方式,应大力推广.

| Abstract: | Objective] To alleviate water resource shortage situation for farmland irrigation in Guizhou Province,achieve water resource effective utilization and optimization configuration,continuous rice water-saving irrigation experiments were carried out for summarizing the most suitable irrigation mode.Method] Using scientific irrigation,scientific storage and general irrigation,effects of different irrigation ways on rice agronomic traits,water amount,water productivity were analyzed.Result] Under the mode of scientific storage,the net irrigation quota is minimum(3 979.50 m3/hm2),rice yield(9 024.00 kg/hm2) and water productivity(3.28 kg/m3) are the highest,which shows that the scientific storage is obviously better than other two irrigation modes.Conclusion] As the most suitable way for farming in Guizhou Province,scientific storage mode should be generalized. |
