Description
Technical Field
The invention belongs to the technical field of plant disease detection, and particularly relates to a rapid detector based on yellow dragon disease and a using method thereof.
Background
The traditional yellow dragon disease information of the grapefruits simply depends on manual collection and laboratory identification, the detection process is tedious, time-consuming and long, labor intensity is high, cost is high, portable detection equipment is lacked, the yellow dragon disease infection condition at each stage in the growth process of the grapefruits cannot be accurately and rapidly detected, and the yield and quality of the grapefruits are greatly affected.
Through long-term research and practice, domestic researchers adopt more methods for detecting the yellow dragon disease, such as a field diagnosis method, a pathogen microscopic observation method, a chemical detection method and a PCR detection method. Such as: in 2014, the yellow-sunset and the like distinguish the affected fruit trees from the normal fruit trees according to the quality and the taste of the fruits of the affected fruit trees and the normal fruit trees in autumn, and the changes of the new leaves of the branches of the affected fruit trees in spring turn green and yellow, the whole plants can be expanded, and the like. The agricultural university of south China Luo Zhida and the like finish the field diagnosis of the yellow dragon disease by observing the whole disease process of the fruit tree from various specific Huang Shao symptoms at the initial stage of the disease of the infected fruit tree, specific characters at the middle and later stages of the disease, and eliminating interference factors such as yellow tips caused by deficiency, and the like on the basis of field practice. In 2011, the research of Hui Ming et al has been carried out for many years, and it has been proposed that the yellow dragon disease infection is diagnosed by using electron microscope technology to select the serious mottled leaf blade and comparing the slight mottled leaf blade to detect yellow dragon disease more easily, and the tangent plane of the serious mottled leaf blade is based on the unique position and cell wall characteristics of the yellow dragon disease in the sieve tube. Wang Xuhui to Fujian university of agriculture and forestry et al in 2017 proposes a method for optimizing the decoloring step to shorten the decoloring time from 11.6-13.2 h to 3.6-3.8 h based on the iodine-starch reaction, and omitting the freezing step. After optimization, the interference of chlorophyll and normal accumulated transitional starch on the detection result is avoided, the accuracy and the repeatability of the detection result are improved, and the method has important significance for diagnosis of yellow dragon disease. In 2017, yao Li, the suspected yellow dragon disease leaves are subjected to sampling and freezing for 12 hours, then the suspected yellow dragon disease leaves are subjected to multiple times of slicing by using a rapid field detection kit for the orange yellow dragon disease, and whether the leaves are infected with the yellow dragon tablets is confirmed by visually observing whether the leaves are discolored. The method can accurately, rapidly and accurately detect the yellow dragon disease, and judge whether the yellow dragon disease is affected by human eyes or not, but has certain uncertainty.
The application of the spectroscopic technology in yellow dragon disease detection in China is in a great development stage, and certain achievement is achieved. Such as: in 2020, weng Haiyong and the like research the influence of pathogenic bacteria on the absorption, distribution and utilization of light energy in the photosynthesis process of a host, and the rapid diagnosis of citrus yellow dragon disease is realized by adopting a chlorophyll fluorescence imaging technology.
The hyperspectral images of normal leaves and yellow dragon disease leaves show that the absorption peaks of the two leaves at 540nm are different, and the absorbance of the yellow dragon disease leaves is slightly larger, mainly because the yellow dragon disease can prevent the leaves from absorbing water, so that the water content of the leaves is lower. From the appearance, citrus is obtained with yellow dragon disease and nitrogen deficiency, the color of the leaf is very similar, and the leaf is difficult to distinguish by naked eyes. The absorption peaks of hyperspectral images of normal and yellow dragon disease and nitrogen deficiency are not different, so that the absorbance of the leaf with nitrogen deficiency is obviously different from that of the leaf with yellow dragon disease by adopting first-order guiding treatment on three types of images.
For conveniently and rapidly detecting whether the grapefruit has the yellow dragon disease, the application document provides a rapid detector based on the yellow dragon disease.
