- Abstract
Saline alkali soil is used as spare arable soil, and its improvement is necessary for its development and utilization. There are many research studies on improving saline-alkali soil by using organic wastes produced by various industries, but there are few studies on using wastes produced by traditional Chinese medicine enterprises for saline alkali soil improvement. The purpose of this study was to explore the improvement effect of using Ganoderma lucidum residue (GLR) organic fertiliser on saline alkali soil and determine the application amount of GLR organic fertiliser with the best improvement effect. The results showed that the pH, EC and cation leaching loss of the leaching solution of the soil treated with GLR organic fertiliser were significantly higher than those of the unmodified soil. After leaching, the pH, EC, and base ions of the soil were significantly lower than those of unmodified saline alkali soil. The coefficient score of PCA was significantly higher than that of the unmodified saline alkali soil. When the ratio of organic fertilizer to saline-alkali soil was 1:3 and 1:5, the comprehensive evaluation level of the improvement effect was the highest, which could effectively reduce the soil saline-alkali index and promote the leaching of salt in saline-alkali soil.
