摘要
本研究通过分析大球盖菇种植后对土壤p H值、全盐量、有机质、速效钾和铵态氮含量的影响,研究种植大球盖菇对盐碱土的改良作用。结果显示,在两个不同地点的试验地中,与原地土壤相比,种植过大球盖菇的土壤p H值和全盐量均有所降低,p H分别降低了2.94%、2.46%,全盐量分别降低了42.36%、3.08%;与对照组CK相比试验地I、试验地II中试验组A中有机质、速效钾和铵态氮含量显著增加,其中试验地I中的速效钾增加了6.17%、铵态氮增加了11.85%;试验地II中的土样速效钾增加了76.77%、铵态氮增加了164.39%。说明种植大球盖菇对改善盐碱土理化性质具有积极作用。
The aim of the article is to investigate the effects on pH, total salt content, organic matter, available potassium and ammonium nitrogen content of the soil after planting Stropharia rugosoannulata in it, and study the improvement on saline-alkali soil by planting S. rugosoannulata. The results showed that compared with the control group CK, the pH value and total salt content of experimental group A in experimental site I and experimental site II were reduced, and the pH of experimental group A in experimental site I was reduced by 2.94% compared with control CK. The total salt content was reduced by 42.36%.Compared with the control CK, the pH of experimental group A in Experimental Site II was reduced by 2.46%, and the total salt content was reduced by 3.08%. Compared with the control group CK, the contents of organic matter, available potassium and ammonium nitrogen in experimental group A in experimental site I and experimental site II increased significantly. Among them,the available potassium in experimental site I increased by 6.17% and ammonium nitrogen increased by 11.85%;The soil sample available potassium in Experimental Site II increased by 76.77% and ammonium nitrogen increased by 164.39%. It shows that the Stropharia rugosoannulata has a positive effect on improving the physical and chemical properties of saline-alkali soil.
