水稻秸秆还田下化肥减量对油菜产量及效益的影响

Effect of Fertilizer Reduction under Rice Straw Returning on Yield and Benefit of Rapeseed

为了研究水稻秸秆还田下化肥减施对油菜产量和效益的影响,在芜湖市试验地设置了6个处理小组,观察水稻秸秆还田下不同施肥处理对油菜农艺性状及产量的影响。结果显示,Ⅲ组处理的产量与产值均表现最高,显著的高于其他处理组,较对照组分别提高了26.86%、26.65%。扣除肥料成本后的效益以Ⅲ组最高。结论:Ⅲ组水稻秸秆还田下化肥减施量最有利于提高油菜种植的经济效益。

In order to study the effect of fertilizer reduction under rice straw returning to field on the yield and benefit of rapeseed,this study took Wuhu City,which is a major rapeseed planting province,as the research experimental site.Six treatment groups were set up,and each group was divided into three parallel groups.The agronomic traits of rapeseed were observed after maturity and the yield was calculated.The reduction of fertilizer application under rice straw returning in GroupⅢwas the most beneficial to improve the economic benefit of rapeseed planting.
