野生马鞍菌不同土层土壤养分分析
Analysis of Soil Nutrients in Different Soil Layers of Wild Helvella elastica
摘要
Abstract
In order to clarify the relationship between the occurrence of wild Helvella elastica and the ecological environment and soil environment,and then provide some reference for the domestication and cultivation of Wild Helvella elastica.This study investigated the ecological environment where wild Helvella elastica occurred in Kelan,Shanxi Province,and determined the soil pH and nutrient content(including organic matter,alkali hydrolyzable nitrogen,available phosphorus,available potassium,effective coppper,effective zinc,effective iron,effective manganese)in the different soil layer(0,5,10 cm)and different distance(0,50,100 cm).The results showed that the pH of the soil where the wild Helvella elastica occurred was between 7.89 and 8.23,showed an alkaline state.And the soil contained organic matter was 26.37 g·kg-1,alkali hydrolyzable nitrogen,available phosphorus,available potassium,effective coppper,effective zinc,effective iron,effective manganese were 129.61,9.16,157.80,0.82,6.12,4.86 and 15.25 mg·kg-1.The nutrient content in the surface soil where wild Helvella elastica occurs was higher than that in the deep soil,and with the increase of soil depth,the content of soil organic matter,alkali hydrolyzable nitrogen,available phosphorus,available potassium,and available manganese were gradually reduced.Meanwhile,the content of organic matter,alkaline hydrolyzable nitrogen,available copper,available zinc,and available iron in occurrence soil were higher than that in non occurrence soil,while the content of available phosphours,available potassium,and available manganese were lower than that in non occurrence soil.According to the grading standards of the second national soil census,it can be seen that wild Helvella elastica are more likely to occur in alkaline soil with moderate organic matter content,phosphorus deficiency,and potassium enrichment.关键词
