摘要/Abstract

摘要： 【目的】 研究不同添加物配方对棉秸秆腐熟过程中相关指标和微生物数量的变化。【方法】 以棉秸秆为原料,设置不同的添加物配方,进行棉秸秆堆肥腐熟发酵。对其发酵相关指标(温度、pH、电导率、速效氮、磷、钾浓度)及主要微生物变化进行测定分析。【结果】 3种处理的温度、pH、电导率、速效氮磷钾的变化趋势基本相同,但相对含量不同,不同处理下的微生物数量也均不同。【结论】 处理3(基础配方+磷酸二氢钾2%)堆肥发酵效果最优,pH值为8.59~8.89,EC值为4 ms/cm左右,更适宜堆肥发酵。

Abstract: 【Objective】 To explore the changes of related indicators and the number of microorganisms during the maturation process of cotton straw with different additive formulas. 【Method】 In this experiment, cotton stalks were used as raw materials, and different additive formulas were set up to perform cotton stalk compost composting and fermentation. The fermentation-related indicators (temperature, pH, electrical conductivity, available nitrogen, phosphorus, and potassium concentrations) and major microbial changes were measured and analyzed. 【Result】 The results showed that the trends of temperature, pH, electrical conductivity, and available nitrogen, phosphorus, and potassium of the three treatments were basically the same, but the relative contents were different, and the number of microorganisms under different treatments were also different. 【Conclusion】 Treatment 3 (basic formula + 2% potassium dihydrogen phosphate 2%) was the best. The pH value was 8.59-8.89 and EC value was about 4 ms/cm, which was more suitable for composting fermentation.

Key words: cotton straw; compost fermentation; pH; EC; number of microorganisms
