The plant disease detector works by placing the harvested virus-infected plant leaves on the instrument and comparing it with the internal storage data of the plant disease detector to determine the type of virus that the plant is affected by. People will ask, based on what sort of internal storage of plant disease data? Here's the content for everyone to explain:
The first is to understand that plants can change both physiologically and morphologically after they become ill. An abnormal phenomenon of the external morphology of the diseased plant is the symptom. The abnormal performance of a plant itself is often referred to as a pathological condition; after a plant becomes ill, the characteristic structure formed by the pathogenic organism at the affected part of the plant is called a disease condition.
The first one is based on the type of condition: First, discoloration, including chlorosis, yellowing and mosaic. The second is necrosis, including spotting, dead, perforation, sores, ulcers, tumbling or standing. Third, rot, according to the site, can be divided into root rot, stem rot, fruit rot, flower rot, etc.; with the color change, can be divided into brown rot, white rot and black rot, etc.; according to the degree of tissue decomposition, there are dry Corruption, wet rot, and soft rot. The fourth is wilting, which refers to the withering phenomenon of vascular tissue in the roots or stems of plants. The wilting can be partial or whole. Fifth, deformity, refers to abnormal growth of plants, and promote the various organs of the plant metamorphosis, divided into dwarfism, leggy, clumping, leaf rolling, fern leaves, shrinking leaves, hair roots, flag leaves, tumors, bacteria.
The second is based on the type of disease: First, powdery, refers to the pathogenic fungi form black, white, rust-colored powdery objects in the victim part of the plant; Second, moldy, refers to the pathogenic fungi form white, brown, in the affected parts of the plant, Black mold layer; third is a small black spot, refers to the pathogenic fungi in the plant parts of the formation of small black particles; Fourth, sclerotia, refers to the pathogenic fungi in the affected parts of the plant to form different sizes of brown or black particles; five is white rust, Refers to the white porcelain formed by the pathogenic fungi in the affected parts of the plant; the sixth is the pyogenic and bacillary dysentery, which refers to the mucus and gelatinous granules formed by the pathogenic bacteria in the affected part of the plant.
The third is based on non-invasive diseases and invasive diseases: infective diseases. Infectious diseases are caused by the infestation of pathogenic microorganisms, also called parasitic diseases. This type of pathogen can reproduce, spread and spread rapidly under suitable conditions, often causing plant dangerous diseases. The pathogens of invasive diseases mainly include fungi, bacteria, viruses, phytoplasma, nematodes and parasitic seed plants. Phytoplasma is a newly discovered microbe between viruses and bacteria in recent years. Non-infectious diseases. Non-invasive diseases refer to diseases caused by freezing, sunburn, drought, sputum, lack of fertilizer, and other abiotic factors, also called physiological diseases. This disease may also lead to the occurrence of infectious diseases. Although they are of different nature, they have a close relationship with each other. The occurrence of non-invasive diseases can open up invasive pathways for pathogens of invasive diseases. For example, physiological rot of burns is the pathway for the invasion of pathogens, and the development of invasive diseases also reduces the adverse environment of plants. The adaptability makes it easy for plants to have non-invasive diseases.
According to the above three aspects, they are input into the internal storage part of the plant disease detector and classified. Comparing the diseased leaves to the three aspects, the types of plant diseases can be quickly obtained.
