早稻湘辐93-4节水栽培

WaterSaving Culture of Early Rice Xiangfu 934

以耐旱早稻品种湘辐９３－４为供试材料，研究常规灌溉（对照）、湿润灌溉、不灌溉、限量间歇灌溉等不同灌溉方式对植株性状和产量的影响．结果表明，它们主要影响水稻分蘖、成穗和结实，且其中有三种处理比对照增产．

A droughtreststant early rice variety,xiangfu 934 was used to study the influence different watersaving methods of irrigation on the plant's charaters and the yield.The results showed that five types of treatment,including Not Irrigation(NI),Moist Irrigation(MI)and three kinds of Intermittent Quota Irrigation(IQI),save irrigational water obriously compared with the Conventional Irrigation (control).They mainly influ enced the max tiller,the rate of panicles to tillers and the rate of seed set.The yields of xiangfu 934 by three treagmenst(MI,once every 7 and 10 days of IQI)were higher than that of the control.
