为探讨旱稻在拔节孕穗期对水分胁迫的响应，以旱稻80为试验材料，通过盆栽方式，研究了拔节孕穗期不同土壤水分处理对旱稻农艺性状及产量的影响。结果表明：土壤水分控制
- Abstract:

In order to investigate the response of upland rice to moisture stress at jointing and booting stage,Handao 80 was used as experimental materials to study the effects of different soil moisture treatments on the agronomic traits and yield of upland rice through pot experiments at the jointing-booting stage.The results showed that when the soil moisture control less than treatment 5(soil relative moisture content 95%-100%),the plant height,tiller number,leaf area and dry matter weight were decreased with the moisture decreased.At the same time,the effective panicle number and seed setting rate were changed little,but 1000-grain weight especially grain number per panicle were decreased,respectively,resulting in a significant decline in upland rice yield.During jointing-booting stage,the soil relative moisture content must be more than 95%,otherwise the yield of upland rice will be decreased significantly.
