调查测定了河南民权黄河故道刺槐(Robinia pseudoacacia L )与杨树(Populus spp)混交林与刺槐纯林的生长情况及土壤化学性质,通过SAS软件,用方差分析和多重比较的方法以对比分析刺槐与杨树混交对林木生长和土壤化学性质的影响.研究表明:杨树与刺槐混交林明显促进刺槐的生长,提高林分的生产力;混交林中刺槐的平均树高与胸径要高于刺槐纯林;刺槐、杨树混交林林地土壤的理化性质得到明显改善,混交林地土壤养分、土壤微生物含量以及土壤酶活性较刺槐纯林都有显著提高.
調查測定瞭河南民權黃河故道刺槐(Robinia pseudoacacia L )與楊樹(Populus spp)混交林與刺槐純林的生長情況及土壤化學性質,通過SAS軟件,用方差分析和多重比較的方法以對比分析刺槐與楊樹混交對林木生長和土壤化學性質的影響.研究錶明:楊樹與刺槐混交林明顯促進刺槐的生長,提高林分的生產力;混交林中刺槐的平均樹高與胸徑要高于刺槐純林;刺槐、楊樹混交林林地土壤的理化性質得到明顯改善,混交林地土壤養分、土壤微生物含量以及土壤酶活性較刺槐純林都有顯著提高.

@@@@This article surveys the growth and soil chemical property of the mixed forest of Robinia pseudoacacia L,populus spp and pure forest of Robinia pseudoacacia L in ancient riverbed of the Yellow River.Use the SAS, through analysis of variance and multiple comparison ,Relative analysis the mixed forest of Robinia pseudoacacia L and populus spp is influence for the growth and soil chemical property.Study have shown:the mixed forest of Robinia. pseudoacacia L and populus spp can promote the growth of the Robinia pseudoacacia L,improve the productivity of the stand. The average of the tree height and the diameter of the tree in mixed forest; The Physi?cal and chemical properties of the soil is improve in mixed forest of Robinia pseudoacacia L and populus spp , the soil nutrients,the content of the edaphon and the activities of the soil enzyme is higher than the pure for?est of Robinia pseudoacacia L.
