Problems solved by technology

However, the current methods are often not very versatile, for example, some index systems are only applicable to farmland soil in specific areas; there are too many indicators, and there is a strong correlation between the indicators, making it useless to detect too many in soil health evaluation indicators, resulting in a waste of testing resources; the coverage of indicators is not comprehensive, and it is difficult to evaluate the impact of farmland soil on crop output

Abstract

The invention discloses a farmland soil health evaluation method, comprising: selecting a soil evaluation system; screening the soil health indicators in the soil evaluation system by Delphi method to obtain the screened soil health indicators; Standardize the raw data of soil health indicators, perform principal component analysis on the standardized data, and use the indicators included in the main factors that meet the preset conditions as the second soil health evaluation indicators; Stepwise regression analysis to obtain the third soil health evaluation index, and construct a soil health evaluation data set according to the third soil health evaluation index; obtain soil samples and crop samples, and measure the index value of the third soil health evaluation index; According to the index value of the third soil health evaluation index, the soil health index and soil health grade of the soil sample are obtained through the preset scoring rules.

Description

technical field [0001] The invention relates to the field of soil evaluation, in particular to a farmland soil health evaluation method. Background technique [0002] Soil health is a comprehensive measure of the soil's ability to sustain the productivity of organisms within an ecosystem, protect the quality of the environment, and promote the health of plants and animals. Soil health assessment was mainly based on single soil physical and chemical indicators in the early days. The current soil assessment is more comprehensive than that in the early days, and generally includes soil biological indicators. However, the current methods are often not very versatile, for example, some index systems are only applicable to farmland soil in specific areas; there are too many indicators, and there is a strong correlation between the indicators, making it useless to detect too many in soil health evaluation indicators, resulting in a waste of testing resources; the coverage of indic...
