- 摘要:
- 为解决黑龙江省西部地区水资源短缺，水稻种植水分利用效率低等问题，开展节水技术研究，最终建立渠道防渗结合间歇灌溉的综合节水模式，实现水稻生产节水、节本、增效。结果表明：采用渠道防渗技术可减少输水损失，应用间歇灌溉可减少田间灌水损失；集成的综合节水模式和相邻地块的常规种植相比，水稻的有效穗数、每穗实粒数、结实率均有所增加，穗粒重和产量明显提高，产量增加5.87%；WUE总水分提高17.95%；节约成本投入285元·hm-2，经济效益增加1 842.9元·hm-2，增幅14.26%。
- Abstract:
- In order to solve the problems of water shortage and low water use efficiency of rice planting in western Heilongjiang Province,watersaving technology research was carried out,and finally a comprehensive watersaving mode of canal seepage control combined with intermittent irrigation was established to realize watersaving,costsaving and efficiencyincreasing in rice production.The results showed that canal seepage control technology could reduce water loss and intermittent irrigation could reduce field irrigation loss.Compared with conventional planting in adjacent farmer plots,increase effective panicle number,grain number per panicle,seed setting rate,grain weight per panicle and yield increased significantly by integrated watersaving model.And yield increased by 5.87%,water use efficiency increased by 17.95%,costsaving input 285 yuan·hm-2,and economic benefit increased 1 842.9 yuan·hm-2,which increased by 14.26%.
