Effects of Planting Different Shrubs under Osmanthus fragrangs 'Xionghuanggui' on Stand Factors and Soil Physical and Chemical Properties
In order to provide scientific basis for planting suitable shrubs under Osmanthus fragrangs'Xiong-huanggui'and improving planting environment,taking O.fragrangs'Xionghuanggui'+Loropetalum chinense var.rubrum(Ⅰ),O.fragrangs'Xionghuanggui'+Camellia japonica(Ⅱ),O.fragrangs'Xionghuanggui'+Acer palma-tum'Atropurpureum'(Ⅲ)and O.fragrangs'Xionghuanggui'+Euonymus japonicus'Aurea-marginatus'(Ⅳ)as re-search objects,effects of planting different shrubs under O.fragrangs'Xionghuanggui'on stand factors of O.fra-grangs'Xionghuanggui'and soil physical and chemical properties were analyzed.Results showed that average DBH,average tree height,average clear bole height,average crown width,average canopy density and average stand density in standⅢwere the highest.Contents of soil organic matter,total potassium,available potassium,total phosphorus and total nitrogen as well as moisture content and pH in stand Ⅲwere the highest.Soil bulk density in standⅢwas the lowest.Planting A.palmatum'Atropurpureum'under O.fragrangs'Xionghuanggui'had the largest effect on soil physical and chemical properties and was more beneficial to growth of O.fragrangs'Xionghuanggui'.After cultivation,attention should be paid to application of nitrogen,phosphorus and potassi-um fertilizers and addition of organic matter to improve healthy growth of O.fragrangs'Xionghuanggui'.
