生物炭和有机肥施用对辣椒生产及土壤肥力的影响
Effects of Applying Biochar and Manure on Pepper(Capsicum spp.)Production and Soil Fertility
摘要
Abstract
This study aims to clarify the effects of applying pig manure and/or biochar on soil fertility and pepper(Capsicum spp.)productivity and the potential of applying manure on the basis of chemical fertilizer reduction in pepper production.Four treatments were designed,including pure chemical fertilizer(NPK),chemical fertilizer+biochar(NPK+B),manure compost nitrogen replacing 20％chemical fertilizer nitrogen(NPKM),and manure compost nitrogen replacing 20％chemical fertilizer nitrogen+biochar(NPKM+B).The results showed that compared with NPK,NPKM and NPKM+B increased the pepper yield by 31％,reduced the incidence of viral diseases,increased the leaf chlorophyll content,plant biomass,nutrient uptake,and total root length,and decreased the nitrate content of fruits.Compared with NPK,NPKM+B significantly increased the total nitrogen,total phosphorus,and available nitrogen in soil,and increased the vitamin C content of fruits.Multiple plant growth traits and soil fertility indicators were significantly correlated with the fruit yield,fruit quality,and disease incidence.In summary,the application of pig manure and biochar could improve soil fertility while decreasing the incidence of typical soil-borne diseases,thus improving the fruit yield and quality and promoting the green,safe,and sustainable development of the pepper industry.关键词
