水稻免耕机插质量、生长特性及产量形成
Effect of No-Tillage on the Quality of Mechanical Transplanting,Growth and Grain Yield of Rice
摘要
Abstract
Quality of mechanical transplanting, rice growth and grain yield was determined under no-tillage and mechanical transplanting in a field experiment with Zhongzheyou 1 ,Yongyou 9 and Yangliangyou 6 as material.The results showed that soil bulk density decreased from 1.0-1.1 g/cm3 to 0.8-0.9 g/cm3 after 15 days soaking in 0-25 cm soil layer.The seedling planting depth significantly decreased by 40% under no-tillage,but the lodging and floating seedling rate increased.The total root biomass decreased under no-tillage,but the upper root percentage significantly increased compared with conventional tillage.For Zhongzheyou 1 and Yongyou 9,the percentages were 77��18% and 77.08%,respectively.Grain yield under no-tillage declined compared with conventional tillage,which was attributed to higher panicle number per square meter,lower grain number per panicle,seed setting rate and 1000-grain weight.关键词
