GB/T 37802-2019Specifications for site selection and monitoring of farmland information station (English PDF)

3.1 Farmland information monitoring point

It is used for long-term continuous collection of monitoring information on farmland environmental information and crop growth status information of fixed plots.

3.2 Farmland microclimate

A small range of climatic conditions in a crop growing area, consisting of farmland gas-filled layers, physical processes between soil layers and crop groups, and biological processes.

A small range of environments formed by interactions.

Note. Farmland microclimate indicators include radiation, air temperature and humidity, wind, carbon dioxide, and soil temperature and humidity in the farmland gas layer.

3.3 Farmland soil environment

Microenvironment for crop root growth in farmland soil.

Note. The farmland soil environment generally includes soil temperature, soil water content, soil organic matter and mineral nutrients, soil pH, and soil microbial environment.

3.4 Crop growth

The status and trends of individual and population growth of crop plants.

Note. Crop growth can be described by individual and group characteristics of crops, and crop growth monitoring includes ground surveys and remote sensing monitoring. Crop growth characteristic parameter package

Including individual characteristic parameters, group characteristic parameters and comprehensive parameters (leaf area index), which are specifically represented by the geometric size, shape and color of the crop.
