The research on the variance analysis of soil nutrient in natural secondary soil and water conservation forest with different configuration patterns was completed mainly through the measurement and numerical analysis of soil moisture tester. Three different configurations of natural secondary forests had no significant effect on soil nutrient content. The main reason is that the research area has frequent rainfall, annual rainfall is large, and there are climatic factors such as relatively high air humidity, which makes the difference in the decomposition rate of broadleaf species and coniferous species.
The soil moisture tester studied 4 plantations and 3 natural secondary forests with different configurations in the same age, and the effect of different configurations on soil nutrient content was not significant. Soil and water conservation forests in different aged forests have significant differences in soil nutrient protection. The nutrient content of the first principal component of the 10a plantation forest increased by 127.59% compared with the 5a planted forest. Among them, the protective effect of soil nutrients for 10 years of artificial soil and water conservation forest has reached the level of natural secondary forest.
Through soil moisture tester research found that afforestation, construction of different soil and water conservation forest, can reduce soil nutrient loss, is conducive to the improvement of soil nutrients. The soil moisture content of natural secondary forest was the highest, followed by plantation forest. Among them, the nutrient content of the first principal component of the natural secondary forest increased by 104.17% compared with the planted forest because of the strong correlation between soil nutrients, in order to avoid the repeated use of some potential information analysis, and in order to have a comprehensive and comprehensive research object. Consistency recognition, principal component analysis.
The water and soil conservation forests with different forest ages have no significant difference in soil moisture, mainly because the rainfall in the study area is frequent and annual rainfall is relatively large, which results in the discrepancies in the decomposition rate of broadleaf species and coniferous species. . There are obvious differences in soil water conservation effects between different forest ageing soil and water conservation forests, indicating that the loss of soil nutrients through forestation and afforestation will benefit early forestation. When the soil moisture tester determines that the soil moisture does not change much, it indicates that the formation of natural soil and the increase of its water need a time course.
