- Abstract
【Objective】 Under the condition of reducing fertilizer application, the proportion of amino acid liquid fertilizer suitable for pepper growth was screened in the hope of increasing the yield and quality of pepper. 【Methods】In this experiment, Huiteng No.8 was used as the testing material and 6 treatments were set with conventional fertilization as a control, nitrogen fertilizer reduced by 10%, 20%, 30%, 40% and 50%. The effects of the substitution of the amino acid liquid fertilizer on the growth, yield and fruit quality of the pepper were studied by measuring the growth index, yield and quality index of the pepper. 【Results】The results showed that each treatment had an effect on the growth, yield and fruit quality of pepper. Treatment 4 increased the yield of spicy pepper. Among them, the weight of single fruit, the number of fruits per plant, the yield per plant, and the yield of the plot increased by 0.17%, 28.98%, 10.11% and 24.64%, respectively. At the same time, treatment 4 increased the quality of pepper, fruit shape index, soluble protein, soluble sugar, vitamin C by 12.62%, 10.92%, 3.63% and 30.44%, while nitrate content was 22.61% lower than that of CK. 【Conclusion】In summary, amino acid liquid fertilizer can partially replace fertilizer and treatment 4 (40% reduction of nitrogen fertilizer by supplementing 28 kg/667m2 amino acid liquid fertilizer) can be used for base application and topdressing so as to improve pepper yield and quality, and this method can be popularized and applied in production.
