Study on the Soil Nutrient in Different Forest Types in Miyaluo Forest Area of Western Sichuan
摘要
Abstract
In this paper, by using the method of soil sampling and laboratory analysis, the soil nutrient of dif- ferent forest types in Miyaluo forest area of western Sichuan have been investigated. The results showed that. （1） the order of the soil organic matter contents in the different forest types was fir forest（FF）〉40 a Picea baifouriana--Lariac kaempferi plantation （D） 〉 70 a Picea baifouriana plantation （F） 〉 40 a Picea baifouriana plantation？〉shrub forest（SF） 〉birch forests（BF） 〉40 a Larix kaernpferi plantation（B） 25 a Picea baifouriana--Lari：c kaernpferi plantation （A） 〉 55 a Picea baifouriana plantation （E）, and the maximum soil total N content in different forest types was found in FF; （2） the maximum soil total K content in different forest types was observed in B, the maximum soil available K content was found in D; （3） the maximum soil total P content was observed in B in the different forest types, and the maximum soil available P content was found in E; （4）there was great significant negative correlation between soil pH and soil organic matter content, and negative correlation between soil pH and soil total N. The significant positive correlation was found between soil organic matter content and soil total N, and soil available P and soil total K had negative correlation with soil organic matter content. There was no obvious correlation between soil total K and available K, as well as soil total P and soil awilahlo P关键词
