Device and method for detecting content of protein in tomato leaves by multi-angle in situ spectrum

Abstract

The invention relates to the technical field of spectrum detection, and particularly relates to a device and a method for detecting the content of protein in tomato leaves by multi-angle in situ spectrum for tomato planting. The device comprises a spectrum probe and a light source, and further comprises an all-dimensional gyroscope and a light insulating device, wherein the all-dimensional gyroscope consists of an arc-shaped suspension plate, a circular ring track plate, an electric-driven roller and landing legs. The method comprises the following steps: (a) preparing for equipment; (b) correcting a spectrum white board; (c) automatically adjusting and sampling an angle of a leaf spectrum; (d), multi-sampling the leaf spectrum; and (e) calculating a physicochemical value. The device is arranged in a tomato planting field, and can obtain spectrum data of the content of the protein in the alive tomato leaves. The tomato leaves can be measured from multiple angles in an all-dimensional manner; the electric-driven roller automatically rotates, and meanwhile, a camera is matched for performing observation monitoring, so that the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of spectral detection, in particular to a spectral device used for detecting the protein content of tomato leaves at the tomato planting site. Background technique [0002] Tomato fruit contains a lot of nutrients such as carbohydrates, proteins, amino acids, vitamins and inorganic salts. Therefore, tomatoes are very popular among ordinary people in our country, and the annual output is very large. During the growth of tomato plants, the protein content in the leaves can resist free radicals produced by abiotic stress, provide protection for plants, monitor the protein content indicators during the tomato growth process, analyze the reasons for the changes in the protein content indicators, and provide guidance for tomato planting decisions It provides a scientific basis for the rational water and fertilizer management of tomato planting. [0003] The determination of protein content in tomato leaves is st...

Problems solved by technology

The use of chemical determination methods is time-consuming and laborious, requires more labor costs, and the analysis process has more mechanical operations, and is generally not suitable for analyzing a large number of samples; chemical analysis requires the use of chemical reagents, which will inevitably pollute the environment. Due to the accuracy of data, convenient operation and environmental protection and pollution-free characteristics, the use of spectroscopy technology to replace conventional chemical analysis methods has been applied to a certain extent

[0004] like figure 1 As shown, due to the different growth shapes of tomato leaves, the on-site measurement has high requirements on the projection angle of the light source and the incident angle of the spectral probe. Most of the existing tomato leaf protein spectral detection methods use picking new leaves and bagging crushed ice to keep them fresh to prevent leaf deterioration. In order to affect the accuracy of protein spectral measurement, the real-time requirements for measuring protein content are high
