秸秆还田替代磷钾肥对水稻产量和经济效益的影响
Effects of Straw Returning as Substitution for Phosphorus and Potassium Fertilizer on Rice Yield and Economic Benefit
摘要
Abstract
[Objective]To explore phosphorus and potassium fertilizer rate in the condition of straw returning.[Method]Effects of straw returning as partial substitution for phosphorus and potassium fertilizer rate on yield and economic benefit of rice were studied.[Result]The treatment of straw returning plus application of chemical fertilizer decreased the yield of rice by 2.0%,compared with no straw returning.The yield of straw returning as 30% substitution for phosphorus and potassium was the highest,which could increase the effective panicle number and grain number per spike.Economic benefit of straw returning as 30% substitution for phosphorus and potassium was the highest,and the output value and net income were increased by 0.6% and 1.2% than those of NPK,respectively.[Conclusion] In general,straw returning as 30% substitution for phosphorus and potassium fertilizer was the most significant in this experiment,which could increase the yield and economic benefit of rice.关键词
