秸秆覆盖与灌水深度对湘南晚稻产量、米质与水分利用的影响
Effect of Straw Mulching and Irrigation Depth on Yield, Rice Quality and Water Utilization of Late Rice in Southern Hunan
摘要
Abstract
To establish the high-yielding and efficient cultivation technique system for late rice in southern Hunan,field experiment was conducted to comparatively study the yield,quality and water use efficiency of late rice under different conditions of straw mulching and irrigation depth with material of Fengyuanyou 299 in Hengyang county.The results showed that the tillers of deep irrigation treatment (DIT) were more,while its earbearing tiller percentage was lower.Leaf area index of DIT was bigger,while its decrease after booting stage was bigger.The dry matter weight of no-mulching treatment (NMT) was higher than that of mulching treatment (MT),while there was no clear difference between DIT and shallow irrigation treatment (SIT).The rice yield had no clear difference between NMT and MT,while that of SIT was significantly higher than that of DIT by 4.2％-4.6％,and the difference in yield was induced by effective panicles.The irrigation depth and straw mulching had no effect on processing quality of rice,while shallow irrigation could improve performance and tasting quality,and straw mulching had adverse effect on performance and tasting quality.Shallow irrigation could significantly improve water utilization efficiency,while straw mulching had little impact.In this study,straw mulching had no clear effect on late rice in southern Hunan,while shallow irrigation could improve yield,quality and water use efficiency of later rice.关键词
