摘　　要：为了探究有机肥完全替代化肥对辣椒产量、品质、病虫害发病率及土壤理化性质的影响,采用大田小区试验,设置纯化肥(CK)、有机肥1、有机肥2、有机肥3等4个处理,测定辣椒产量、可溶性糖含量、可溶性蛋白含量、硝酸盐含量、病虫害发病率及土壤理化性质。结果表明:与CK相比,有机肥处理的辣椒总产量提高了37.76%~42.54%,可溶性糖与可溶性蛋白含量分别提高了38.10%~51.07%和20.03%~25.29%,硝酸盐含量降低了8.47%~24.37%;但有机肥降低辣椒病虫害发病率的效果不明显;土壤有机质和碱解氮分别提高了9.72%~11.74%和2.68%~10.04%。综合结果分析,有机肥完全替代化肥能够提高辣椒产量和品质,改善土壤理化性质,其中,有机肥3(N 1.99%、P2O52.29%、K2O 1.36%,含水量25.76%)的效果最好。Field plot experiments were conducted to explore the effects of complete replacement of chemical fertilizer with organic fertilizer on the yield,quality,disease and pest incidence of capsicums and the physicochemical properties of soil.Four treatments were designed,including pure chemical fertilizer(CK),organic fertilizer 1,organic fertilizer 2,and organic fertilizer 3.The yield,soluble sugar content,soluble protein content,nitrate content,and disease and pest incidence of capsicums and the physicochemical properties of soil were determined.The results showed that compared with CK,organic fertilizers increased the yield,soluble sugar content,and soluble protein content of capsicums by 37.76%-42.54%,38.10%-51.07%,and 20.03%-25.29%,respectively,while decreasing the nitrate content by 8.47%-24.37%.However,the effect of organic fertilizer on reducing the incidence of diseases and pests was not obvious.Soil organic matter and alkali-hydrolyzed nitrogen were increased by 9.72%-11.74%and 2.68%-10.04%,respectively.The complete replacement of chemical fertilizer with organic fertilizer improved the yield and quality of capsicums and the physicochemical properties of soil,and organic fertilizer 3(1.99%N,2.29%P2O5,1.36%K2O,and 25.76%moisture)had the best effect.
