蚯蚓粪酸土改良剂对酸性土壤酸碱性、肥力及上海青生长的影响评价
Effects of vermicompost-based acid soil conditioners on acidity-alkalinity and fertility in acidic soil,and growth of Shanghaiqing
摘要
Abstract
Two vermicompost-based acid soil conditioners including B+M+V and BMV were devel-oped by incorporating high-alkalinity substances-oyster shell powder(M)and biochar(B)into vermicom-post(V)through physical mixing and vermicomposting to enhance the improvement performance of vermi-compost acid soil.A pot experiment was conducted to compare the effects of applying B+M+V,BMV,and other amendments including quicklime(L),oyster shell powder(M),biochar(B),and vermicompost(V).The results showed that the effect of reducing the acid in soil was most significant under the applica-tion of L and M,with pH in soil increased by 3.18 and 2.81 units,and soil acid-base buffering capacity(pH-BC)increased by 196.81%and 236.97%,respectively.The effect of reducing the acid in soil was the sec-ond under the application of B+M+V and BMV,with pH in soil increased by 1.35 and 1.49 units,and pH-BC increased by 124.97%and 104.07%,respectively.The effect of reducing the acid in soil was the weak-est under the application of B and V.The application of V,B+M+V,and BMV effectively improved the fertility in soil.Among them,the application of B+M+V and BMV increased the content of organic mat-ter in soil by 197.53%and 222.51%,respectively,while significantly increasing the content of available phosphorus and available potassium,and the value of cation exchange capacity(CEC)in soil.The plant height and biomass of Shanghaiqing under the application of B+M+V and BMV were significantly higher than those under the application of L,M,and B.The accumulated absorption of nitrogen,phosphorus,and potassium by Shanghaiqing were significantly increased under the application of B+M+V and BMV.The results of principal component analysis showed that L and M excelled at reducing the acid in soil,V,B+M+V,and BMV were good at improving the fertility in soil,while B+M+V and BMV were effective in promoting the growth of plant.B+M+V and BMV performed the best in the comprehensive improvement of acid soil.It is indicated that the two types of vermicompost-based acid soil conditioners developed effec-tively combine the advantages of pure vermicompost for improving the fertility in soil and high alkalinity substances for strongly reducing the acid in soil,and can play an excellent comprehensive role in improving acid soils.关键词
