Description
Technical Field
The utility model relates to a plant disease detection area especially relates to a device that is used for yellow dragon to detect.
Background
The yellow shoot is also called citrus yellow shoot, and is a disease with extremely wide range and great harm. The pathogenic bacteria of the yellow dragon disease are special parasitic phloem bacteria of the citrus, and the bacteria infect the phloem and the root system of the citrus to cause the trees to be weak and dead. The Huanglongbing disease usually has a long onset period of 1-3 years. The infected citrus trees have mottled yellow leaves and do not or have inferior fruits.
Yellowing of citrus leaves alone cannot be accurately judged because citrus lacks nutrient elements and can cause yellowing of the leaves due to nematode infection or citrus tristeza. If the yellow dragon disease is judged by simply relying on the yellowing of the leaves, the misjudgment is often caused. On the other hand, the degree of the onset of huanglongbing cannot be determined simply by observing the yellow color of the leaves. Because the degree of the yellow shoot disease is related to the number of colonies of the tree body and the physiological state of the citrus tree body, and the shade of the yellow color of the leaf is not linearly related to the factors.
