Abstract

Abstract:

To investigate the characteristics of decomposition and nutrient release of Vicia sativa under different overturning pressures in the Nanxiong tobacco growing area of Guangdong Province, field decomposition tests were carried out using nylon mesh bags buried in the field for 120 days. The dry matter decomposition rule and nutrient release rate of Vicia sativa under pressure amounts of 20000, 30000 and 40000 kg/hm² were studied. The results showed that the dissolution rate of Vicia sativa increased rapidly in the early stage and slowly in the later stage. The final dissolution rate of Vicia sativa dry matter was 81.90%-84.95% at 120 days. Carbon, nitrogen, phosphorus, and potassium were released in large quantities in the first 30 days after overturning. By the end of the trial, the cumulative release rates of all nutrients reached 80.45%-83.48%, 85.18%-86.98%, 85.19%-87.55%, and 88.15%-91.33%, respectively. Regression analysis showed that the release rate of the most accessible potassium nutrient showed a decreasing trend with the increase of overturning pressure. While carbon and nitrogen nutrients showed a decreasing trend first and then an increasing trend, and phosphorus nutrient showed a decreasing trend first and then a stable trend. The maximum release rate of all nutrients increased with the increase of the overturning pressure of Vicia sativa. According to prediction analysis, the complete release of carbon, nitrogen, phosphorus, and potassium required 200-252, 167-189, 144-157 and 126-143 d, respectively. The increase in overturning pressure had no effect on the overall decomposition and nutrient release rule but had a greater impact on the release rate and speed of nutrients. The increase in overturning pressure could improve the nutrient release rate in the early stage of overturning (within 30 days). Most nutrients of Vicia sativa were released in the early stage after increasing the overturning pressure, which could not provide sustained nutrient supply for crops. Therefore, in actual production, the reasonable overturning amount of Vicia sativa should be determined according to the fertilization characteristics of flue-cured tobacco. This study could provide a theoretical basis for the scientific utilization of green manure crops in the Nanxiong tobacco growing area of Guangdong Province.
