新疆膜下滴灌旱作水稻不同生育期控制性灌溉对产量及农艺性状的影响

Effects of Control Irrigation on Yield and Agronomic Characteristics of Different Fertility Periods of Drip Irrigation for Rice in Xinjiang

试验以水稻新品种新稻50号为试验材料,研究不同生育期控制性灌溉对膜下滴灌旱作水稻产量及农艺性状的影响,试验结果表明:水稻膜下滴灌旱作拔节孕穗期控制性灌溉对株高影响最大、收获穗数最低,穗总粒数、每穗结实粒数明显偏低,结实率低,产量显著下降。

The effects of controlled irrigation on rice yield and agronomic characters of drip-irrigation under membrane were studied in the new rice variety new rice No.50.The experimental results show that:the control irrigation during the rice film drip irrigation during the stage of lugging pregnancy has the greatest effect on plant height,the lowest number of ears harvested,the total number of ears and the number of grains per ear are obviously low,and the seed setting rate is low,which will cause a significant decline in yield.
