Farmland soil health evaluation system

Abstract

The invention discloses a farmland soil health evaluation system, which comprises a data input unit, a processing unit and a result output unit, wherein the data input unit is communicated with the processing unit and is used for inputting the parameter of the health evaluation index of the soil sample and sending the parameter into the processing unit; the processing unit is communicated with theresult communication unit, is used for evaluating the index parameter according to the received soil sample, obtains the soil health index of the soil sample according to the preset evaluation rule,and sends the soil health index to the result output unit; the result output unit outputs the soil health index of the soil sample in a preset form, wherein the soil sample health evaluation index includes a soil physical index, a soil biological index, a soil chemical index and a soil production index; the production index comprises one or several values in the crop yield, the crop quality and the crop commodity qualification rate.

Description

technical field [0001] The invention relates to the field of soil evaluation, in particular to a farmland soil health evaluation system. 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, only using soil physical, chemical and biological indicators as soil health indicators sometimes cannot evaluate the impact of soil use, nor can it fully reflect the degree of soil health. Especially when it is used to evaluate the farmland soil used for crop production, it is difficult to accurately evaluate the growth and output of crops only based on these indi...

Problems solved by technology

[0004] 1. The versatility is not strong, for example, some index systems are only applicable to farmland soil in specific areas;

[0005] 2. There are too many indicators, and there is a strong correlation between the indicators, so that too many useless indicators are detected in the soil health evaluation, resulting in a waste of testing resources;

[0006] 3. The index coverage is not comprehensive, and it is difficult
