研究了有机肥、微生物菌肥和化肥搭配使用对辣椒产量、品质及土壤质量的影响。结果表明，施用有机肥30 000 kg/hm2、微生物菌肥(枯草孢杆菌50亿/mL)900 kg/hm2、尿素540.0 kg/hm2、磷酸二铵 270.0 kg/hm2、硫酸钾38.7 kg/hm2时，辣椒产量最高，为22 853.2 kg/hm2，较施尿素900.0 kg/hm2、磷酸二铵450.0 kg/hm2、硫酸钾64.5 kg/hm2时增产3 006.8 kg/hm2，增产率15.15%，增收5 183.2元/hm2。说明在辣椒生产中，单施化肥或单使有机肥＋生物肥，都不能获得最佳经济效益，有机肥、微生物肥和化肥合理配比才能提高作物的产量和品质。

The effects of organic fertilizer， microbial fertilizer and chemical fertilizer on pepper yield， quality and soil quality were studied. The results showed that the highest pepper yield was 22 853.2 kg/hm2 when organic fertilizer was 30 000 kg/hm2， microbial fertilizer was 900 kg/hm2(bacillus substilis 5 billion/mL)， urea was 540.0 kg/hm2， diammonium phosphate was 270.0 kg/hm2 and potassium sulfate was 38.7 kg/hm2. Compared with the application of urea 900.0 kg/hm2， diammonium phosphate 450.0 kg/hm2 and potassium sulfate 64.5 kg/hm2， the yield increased by 3 006.8 kg/hm2(15.15%) and the income increased by 5 183.2 yuan/hm2. It shows that the optimum economic benefit could not be obtained by applying only chemical fertilizer or organic fertilizer + biological fertilizer， but the yield and quality of crops could be improved only by reasonable proportion of organic fertilizer， microbial fertilizer and chemical fertilizer.
