摘要
对浙江省临安市郊2年生毛竹根际土壤的化学性质分析表明,毛竹根际土壤酸度明显较全土弱,根际土壤交换性氢和交换性铝比全土低,比值分别为076和079;根际土壤含有较丰富的水解氮、有效磷及交换性钾、钙等;根际土壤的总碳量也稍高于全土,比值为105,但其腐殖质组成差异不大,比值为102。毛竹能使根际土壤的养分有效化。
Study of two year old Phyllostachys pubescens forest in suburb Linan,Zhejiang Province,suggests that the acidity of rhizosphere soil(R) under the forest is lower than that of bulk soil (S); R/S values of exchangeable hydrogen and aluminum are 0 76 and 0 79 respectively.There are much more hydrolyzable nitrogen,available phosphate and exchangeable potassium and calcium in rhizosphere soil.Total carbon is more in rhizosphere soil than in bulk soil(R/S=1 05),but composition of humic matter is obscure(R/S=1 02).It indicates that Phyllostachys pubescens is able to activate soil nutrients.
