Abstract:

The effects of different types of peanut organic fertilizer on the growth, yield, quality and soil physicochemical properties of cigar variety Yunxue 38 were discussed, so as to provide a reference for the scientific and rational fertilization of Yunxue 38. Three fertilization treatments, including peanut-based, peanut meal organic fertilizer and local conventional fertilizer, were set up to measure and analyze the agronomic traits, economic traits, chemical composition of tobacco leaves, and physical and chemical indexes of soil after tobacco planting under different fertilization treatments. The results showed that compared with the control, the two organic fertilizers of peanut meal and peanut-based fertilizer could significantly increase plant height and maximum leaf area. The yield of fresh leaves with peanut organic fertilizer could be increased by 3.93%-12.07%. The contents of chemical components such as total nitrogen, nicotine and potassium in leaves increased to varying degrees, and the comprehensive score of chemical components assigned to leaves was the best in peanut meal organic fertilizer treatment. In addition, the application of peanut organic fertilizer could increase the content of soil organic matter, alkali hydrolyzable nitrogen and total nitrogen, among which the treatment effect of peanut meal organic fertilizer was more obvious, which increased by 41.14%, 31.81% and 61.54%, respectively. The results of redundancy analysis showed that organic matter and total nitrogen content were the main influencing factors of agronomic traits of plants, and pH value, organic matter and total nitrogen content were the main influencing factors of chemical composition of leaves. The application of peanut organic fertilizer played an important role in improving the yield quality and soil nutrient indexes of Yunxue 38, and the comprehensive effect of peanut meal organic fertilizer was the best.

Key words: Yunxue 38, peanut based organic fertilizer, peanut meal organic fertilizer, yield and quality, soil physical and chemical properties
