矿物质调理剂配施生物有机肥对坡耕辣椒地土壤质量的影响
Effects of mineral conditioner combined with bio-organic fertilizer on soil quality in sloping pepper farmland
摘要
Abstract
To investigate the improvement effects of a biophysical fertilization model on soil fertility in sloping farmland cultivated with pepper(Capsicum annuum),a field plot experiment was conducted in typical sloping farmland in Xiangtan,Hunan Province.Seven treatments were established:conventional fertilization(CF),CF+1 125 kg/hm2 mineral conditioner(SC),and SC+bio-organic fertilizer at 1 875 kg/hm2(BOF1),3 750 kg/hm2(BOF2),7 500 kg/hm2(BOF3),11 250 kg/hm2(BOF4),and 15 000 kg/hm2(BOF5).We evaluated the effects of co-application of SC and bio-organic fertilizer on soil pH value,soil organic matter(SOM),cation exchange capacity(CEC),nutrient contents,enzyme activities,microbial biomass carbon(MBC),microbial biomass nitrogen(MBN),and microbial biomass phosphorus(MBP)in sloping farmland soil.The results indicated that,compared with the SC treatment,the combined application of SC with varying rates of bio-organic fertilizer increased pepper yield by 29.65%-91.42%and enhanced net benefit by 87.46%-190.85%.These combined treatments also increased the SOM content by 8.65%-23.67%,and CEC by 0.54%-6.90%.The BOF4 treatment significantly increased the contents of soil alkali-hydrolyzable nitrogen,available phosphorus and available potassium by 16.72%,89.32%and 73.31%,respectively,and significantly elevated the contents of soil total nitrogen and total phosphorus by 14.20%and 22.94%,respectively.The BOF4 treatment also significantly enhanced soil urease and sucrase activities by 13.92%and 99.23%,respectively.The BOF3 treatment significantly increased soil MBC by 64.17%,and the BOF4 treatment significantly increased soil MBP by 48.16%.Soil quality assessment revealed that the soil quality index exhibited diminishing returns when the bio-organic fertilizer application rate exceeded a certain threshold.Overall,the combined application of SC and bio-organic fertilizer can increase SOM,expand the soil nutrient pool,and enhance soil enzyme activities and MBC,thereby improving soil quality and pepper yield in sloping farmland.The combined treatment of SC and 11 250 kg/hm2 bio-organic fertilizer(BOF4)exhibits the optimal improvement effect.关键词
