EFFECTS OF RETURNING FIELD OF MUSHROOM RESIDUE ON SOIL PROPERTIES AND FRUIT QUALITY IN PEAR ORCHARD
摘要
Abstract
In this study,the pleurotus ostreatus with overlying soil of 3 different feed amount(10,12.5 and 15kg/m2)were planted in the tree row interval of 7a pear,and the mushroom residue were returned after cultivation with sterile residue returning as control.The results showed that(1) soil bulk density reduced by 7.3% to 14.9%(P0.05),soil porosity increased from 4.2% to 11.5%(P0.05),total soil organic carbon content increased by 32.7%~56%(P0.01) compared with the control,and active organic carbon content increased from 39.2% to 92.5%(P0.01) and active organic carbon ratio in 0~40cm soil layer improved;(2) bacterial numbers increased by 12.1%~47.0%,actinomycetes increased 19.5%~82.8%,the number of fungi increased by 68.7%~163.6%(P 0.01),microbial biomass carbon increased by 13.4%~32.2%(P0.01),and nitrogen increased by 9.3%~37.1%;(3) soil urease activity increased from 23.2% to 47.6%(P 0.05),the activity of invertase increased from 25.7% to 58.6%(P0.01),phosphatase activity increased from 14.8% to 33.6%(P0.01),catalase activity increased from 4.8% to 20.2%,and all of them increased with the amount of mushroom residue;(4) pear fruit weight increased from 9.2% to 15.0%(P0.05),and hardness increased by 3.9%~5.3%(P0.05),soluble solids content increased by 11.7%~19.5%(P0.05),the content of soluble sugar increased from 4.2% to 6.3%(P0.05),titratable acid content decreased from 3.1% to 7.7%.The mushroom residue returning after cultivation of Pleurotus ostreatus in pear tree rows with 15kg/m2 applied for covering soil would increase the soil fertility of 0-40cm soil layer and improve the frwit quality of pear.关键词
