秸秆直接还田应用腐解剂对马铃薯产量的影响

Influence on Potato Yield of Maize Stalk Leftover Combined with Application of Decay Agent

秸秆还田可以改善土壤肥力,具有增产潜力,但是需要一系列技术手段解决秸秆腐解的问题。本研究以玉米秸秆还田添加生物腐解剂,种植马铃薯作物,观察其对产量的影响。结果表明:直接秸秆还田中应用生物腐解剂,对当年马铃薯作物产量的影响不大,没有增产或减产的状况出现,从改良土壤的角度,可能具有一定的增产潜力。

Returning the stalks to field can improve soil fertility,and have potential to increase crop yield.But it needs a series of technical means to solve the problem of stalks decay.In this research,potatoes were planted in a field with maize stalk leftover added with decay agent and the effects were determined for potato yield.The results showed that the maize stalk leftover combined with application of decay agent had little influence on potato in current year,with no yield increase being observed.But from the perspective of soil improvement,this practice might have potential to increase production.
