摘  要：
[目的]研究不同水分处理对水稻和旱稻产量及产量构成因子的影响。[方法]以宁粳16号和旱稻297为试验材料,进行淹水、干湿交替和旱作灌溉处理,观察水稻和旱稻的生长动态变化,研究不同水分处理对其理论产量、实际产量、穗长、穗数、穗粒数、千粒重、结实率、经济系数等的影响。[结果]与淹水灌溉相比,旱作灌溉使水稻和旱稻分蘖期后移,生育期推迟,生长发育缓慢,株高降低,产量降低,穗长变短,穗数不足,穗粒数下降,千粒重降低,结实率下降,经济系数提高;旱稻与水稻相比,旱作灌溉处理对旱稻的影响较小。[结论]该研究结果为水稻抗旱节水栽培提供了参考。

摘  要：
[Objective] The aim was to study the effect of different water treatments on yield and yield components of lowland rice and aerobic rice.[Method] Taking Ningjing No.16 and Handao 297 as tested materials,treatments of flooding,alternate wetting and drying and drying were carried out,observing the dynamic change of growth,researching the effect of different water treatments on theoretical yield,actual output,ear length,ear number,grains per spike,1 000-grain weight,seed setting rate and economic coefficient of lowland rice and aerobic rice.[Result] Comparing with flooding treatment,the characteristics lowland rice and aerobic rice with drying treating was that tillering and growth stages were delayed,growth and development slowing,plant height and yield decreased,ear length shortened,ear number shortcoming,grains per spike,1 000-grain weight and seed setting rate decreased,economic coefficient increased.Comparing lowland rice with aerobic rice,the dry treatment had little effect on aerobic rice.[Conclusion] The result provides reference for rice resisting drought and saving water.
