巨尾桉萌芽林引入降香黄檀后的土壤化学性质变化
Changes of Chemical Property in the Soil of Secondary Eucalyptus Plantation after Introducing Dalbergia odorifera
摘要
Abstract
In order to understand the soil chemical environment change of the Eucalyptus mixed forest after Dalbergia odorifera was replanted,the soil nutrient,enzyme and phenolic content of Eucalyptus pure and mixed forests were detected and then were further compared and analyzed.The results showed that:1) There were the significant difference of the N contents in field and rhizosphere soils between the pure and mixed Eucalyptus plantations.The N content of rhizosphere soil in pure plantation was 87.7% higher than the mixed one while P content was not significant.2) For the activity of urease,the value in the surface soils of mixed forest was higher than that of pure forest,however,the acid phosphatase activity was opposite.For the rhizosphere soil,acid phosphatase activities showed the similar characteristics to urease activity as the both of enzyme activities in the rhizosphere soil of Eucalyptus in mixed plantation were significantly lower than that of Eucaplytus in pure plantation and Dalbergia odorifera in the mixed plantation.3) The contents of total phenol and composite phenol in the rhizosphere soil of pure Eucalyptus plantation were higher than those of mixed plantation although the content of water soluble phenol was lower.The content of water soluble phenol in the rhizosphere soil of Dalbergia odoriferawas obviously higher than the values of Eucalyptus in both of plantations by 32.40% and 43.86% variation respectively.4) The ratios of N/P in rhizosphere soil were no significant while the field soil N/P was 238.8% higher than the mixed plantation.The ratio of N/P had the significant positive correlation with content P while negative correlation with acid phosphatase activity.However,no significant correlation appeared between the ratio of N/P and the content of phenol.There was the extremely significant negative correlation between the types forms of phenol.关键词
