新型复合施肥模式在辣椒上的应用研究

Application of New Compound Fertilization Model on Pepper

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30000 kg/hm^(2)、微生物菌肥(枯草孢杆菌50亿/mL)900 kg/hm^(2)、尿素540.0 kg/hm^(2)、磷酸二铵270.0 kg/hm^(2)、硫酸钾38.7 kg/hm^(2)时,辣椒产量最高,为22853.2 kg/hm^(2),较施尿素900.0 kg/hm^(2)、磷酸二铵450.0 kg/hm^(2)、硫酸钾64.5 kg/hm^(2)时增产3006.8 kg/hm^(2),增产率15.15%,增收5183.2元/hm^(2)。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 22853.2 kg/hm^(2) when organic fertilizer was 30000 kg/hm^(2),microbial fertilizer was 900 kg/hm^(2)(bacillus substilis 5 billion/mL),urea was 540.0 kg/hm^(2),diammonium phosphate was 270.0 kg/hm^(2) and potassium sulfate was 38.7 kg/hm^(2).Compared with the application of urea 900.0 kg/hm^(2),diammonium phosphate 450.0 kg/hm^(2) and potassium sulfate 64.5 kg/hm^(2),the yield increased by 3006.8 kg/hm^(2)(15.15%)and the income increased by 5183.2 yuan/hm^(2).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.
