2、下种植紫穗槐模式山核桃林下施除草剂模式的含氮量较低;山核桃林下种植白三叶模式的全钙的含量66.25mg/kg以及含氮量112.68eCkg最高;山核桃林下种植百喜草模式的含水率17.68%最高,含氮量较高。山核桃林下种植紫穗槐模式样地产量最高,山核桃林下施除草剂模式样地产量最低。经多重比较,不同经营模式山核桃林下,种植紫穗槐模式有效增加山核桃的产量,种植百喜草模式对水分的保持效果最好,土壤pH5.88对山核桃的生长比较有利。关键词:经营模式;土壤养分;山核桃中图分类号:$727.3文献标志码:B论文编号:2014—0486TheEfectofDifferentOperationModes
