浅湿交替节水灌溉对水稻产量及生物学特性的影响
Effects of Different Wet-shallow Alternate Irrigation Patterns on Rice Grain Yield and Bio-logical Characteristics
摘要
Abstract
Effects of four different wet-shallow alternate irrigation methods from transplanting to filling stage on grain yield and biolog-ical characteristics of rice Chujing38 and Yunjing36 were studied in Yunnan fields in 2014. The results showed that the yield were reduced along with the increase of wet-shallow alternate irrigation days, but there were no significant difference in different treat-ments, the yield were decreased by more than 5% in wet-shallow alternate irrigation 7 days. The effective panicles and 1 000 grain weight had no obvious regular pattern, the interaction of yield components made the decrease of grain yield with increasing days of in-termittent irrigation. Compared to the control, rice seedlings tillering ability were increased quickly after transplanting, leaf area index at heading stage increased, dry matter weight of stems and leaf increased. At maturity stage, dry matter weight of stems, leaf and spike had not significant difference by different treatments.关键词
