Soil quality assessment for Carya illinoensis-Paeonia ostii under various patterns
摘要
Abstract
[Objective]The aim of the present study was to investigate the soil physical properties,chemical properties,and enzyme activities under different Carya illinoensis'Pawnee'and Paeonia ostii'Feng Dan'planting modes,as well as analyze the effects of different modes and seasons on soil characteristics.[Method]The treatments included single cultivation of C.illinoensis(mode Ⅰ),compound cultivation of C.illinoensis'Pawnee'-P.ostii'Feng Dan'(modeⅡ),and single cultivation of P.ostii(mode Ⅲ).Seasonal variation of soil physical properties,chemical properties,and enzyme activities were measured under different modes,and the minimum date set method and soil integrated fertility index(IFI)were utilized to evaluate the changes of soil fertility.[Result]The nutrient and enzyme activity in the surface soil were higher than those in the deep soil.The soil moisture content and bulk density gradually varied with the seasons of spring,summer and autumn.There was no significant difference on soil pH between the spring and summer seasons,and the lowest soil pH was observed in autumn.The soil catalase activity in summer was higher than that in spring and autumn.The soil organic matter content,total nitrogen content,available potassium content,sucrase activity,and urease activity increased during the seasonal variation of spring,summer,and autumn.In mode Ⅲ,the soil available phosphorus content in autumn was higher than that in spring and summer.The seasonal variation of the soil IFI was the lowest in summer and highest in mode Ⅱ.[Conclusion]There is a correlation among soil physical properties,chemical properties and enzyme activities.The soil fertility of the compound cultivation of C.illinoensis'Pawnee'-P.ostii'Feng Dan'(mode Ⅱ)is significantly higher than single cultivation of either species,and the soil fertility quality is lower in summer than in spring and autumn.The soil fertility quality is directly affected by bulk density,total nitrogen content,available potassium content,available phosphorus content,sucrase activity,and urease activity.Further,sucrase activity is more sensitive in evaluating the soil IFI in all seasons.关键词
