化肥减量配施不同有机肥对辣椒品质和产量的影响
Effects of Fertilizer Reduction Combined with Different Organic Fertilizers on the Quality and Yield of Chilli Peppers
摘要
Abstract
By comparing the effects of chemical fertilizer reduction and the application of bio-organic fertilizer and'Chunyoujia'on the yield and quality of chilli peppers,it provides a theoretical basis for exploring the measures of chemical fertilizer reduction and improving the yield and quality of peppers.In this study,the pepper variety Longjiao 11 was used as the experimental material.Different treatments,including conventional fertilization(N 439.50 kg/ha,P2O5 298.50 kg/ha,K2O 454.50 kg/ha),reduced fertilizer application in combination with various organic fertilizers and other seven treatments were applied.The quality and yield indexes of peppers were determined for each treatment,and the performance of pepper quality and yield of different fertilization treatments was comprehensively evaluated by principal component analysis(PCA).Results showed that the treatment of 30%reduction in coventional fertilization+bio-organic fertilizer+rice vinegar had the highest content of soluble sugar and vitamin C,which increased by 15.81%and 46.86%,respectively,as well as a yield increase of 1.19%as compared to the treatment of conventional fertilizer.Compared to the treatment of conventional fertilizer,the treatment of 30%reduction in coventional fertilization+'Chunyoujia'+rice vinegar had the highest content of soluble protein and capsaicin,which increased by 23.43%and 6.67%,respectively compared with the conventional fertilization.There was the highest yield in the treatment of 30%reduction in coventional fertilization+bio-organic fertilizer+aspirin+brown sugar,but contents of soluble sugars and soluble proteinswere lower than that of the treatment of conventional fertilizer.PCA indicated that the treatment of 30%reduction in coventional fertilization+'Chunyoujia'+rice vinegar showed the greatest composite score.Therefore,the application of 30%reduction in coventional fertilization+'Chunyoujia'at 150 kg/ha+rice vinegar at 4.3 L/ha diluted with 3 225 kg water can significantly improve the yield and quality of peppers.关键词
