Description

technical field [0001] The invention relates to the field of optics and matrix component detection, in particular to an integrated system for cultivation matrix pretreatment and fast spectrum detection of components. Background technique [0002] Substrate cultivation is not limited by natural soil conditions, and has the advantages of controllable planting environment and high economic benefits, and is widely used in facility agriculture. Facility agriculture is a modern agricultural method that uses engineering techniques such as testing to produce plants efficiently under relatively controllable conditions. Therefore, it is of great significance to detect the components in the cultivation medium and grasp the nutritional status in the cultivation medium environment in time for the realization of precision agricultural planting. [0003] At present, the detection of cultivation substrate components mainly refers to the traditional chemical analysis method of soil componen...

AI Technical Summary

Problems solved by technology

At present, there are many studies on the detection of soil components using near-infrared spectroscopy, but there is no report on the detection and research of cultivation substrates using near-infrared spectroscopy.

The cultivation matrix particles are relatively coarse, the shape of the cultivation matrix particles is irregular, and there are large gaps between the cultivation matrix particles. If the cultivation matrix is ​​directly detected by near-infrared spectroscopy, there will be large scattering and diffuse reflection phenomena. The test results have a great influence

In addition, when performing near-infrared spectroscopy on soil, it is necessary to dry the soil to eliminate the influence of moisture on other detected components, and it is difficult to ensure that the distance between the surface of each sample and the fiber optic probe is consistent.
