Plant disease terminology
2. Plant infestation diseases are relatively non-invasive diseases. Plants are caused by pathogenic parasites and cause infectious diseases. They can also be called parasitic diseases or infectious diseases.
3. The collective name of pathogenic organisms that cause plant diseases, mainly known as fungi, bacteria (like mycoplasmas), viruses (like viruses), nematodes, and parasitic seed plants. In addition, a small number of actinomycetes and algae plants can infect plants, such as potato scab caused by Actinomyces scabies and Cephaleuros virescens causing algae on tea trees and many other evergreen trees. Spot disease. Most plant diseases are caused by fungi. Mycelium is the most common vegetative structure of fungi; sexual planting usually produces spores and is the primary source of plant disease infestation.
4. Parasitic parasites must acquire the biological properties of living substances (moisture, nutrients, etc.) from the cells and tissues of living hosts for their own growth and development. Can be divided into parasitism and fascicular parasitism, parasitism parasitism is parasitic in the natural conditions must be parasitic on the live host in order to grow and develop; fascinating parasitism is that the parasite can live in the host living parasite parasitic life, can also Living in rot or living in dead or organic matter. The vast majority of phytopathogenic fungi and all phytopathogenic bacteria are facultative parasites.
5. Pathogenic pathogens infect pathogenic characteristics of host plants.
6. Symptoms of the disease are discoloration, necrosis, rot, wilting, malformation. Discoloration refers to the change of the original color of a diseased plant, which is the most common and early appearance of a disease type. Discoloration is usually the most obvious in the early stages of viral disease, mainly manifested in many types, such as mosaic, yellowing, streak. Plant viral diseases and some non-invasive diseases (particularly deficiency of the disease) often show discoloration symptoms. Partial or massive death of necrotic tissue. Commonly seen are: leaf spots, dead spots, leaf blight, branches withered, ulcers, standing, perforation, and so on. The rot tissue is affected by various enzymes and toxins of the bacteria. The pectin and the cell wall are broken down, the cells are destroyed, and the original tissue structure and shape are disintegrated. Mainly classified as dry rot and wet rot (soft rot). The vascular tissue in the roots or stems of wilt disease tissue is necrotic and loses its guiding function. In particular, the catheter system is severely damaged, and the water in the roots cannot be transported upwards, resulting in wilting of shoots in the shoots. Abnormal growth of the local tissue of the malformed plant caused by the hormonal substances stimulating effects of pathogens, generally manifested as hyperplasia, hyperplasia, and loss of life.
7. The infectious disease of the disease begins from the previous growing season and continues to develop again in the next growing season. It is composed of several components, such as primary infection, reinfection, wintering (or summer), and transmission. Pathogens that infect for the first time winter or summer infestation cause initial infestation after the plant begins to grow and are called primary infestations. Once again infested plants that have been infected for the first time can produce spores or other propagules that can cause re-infestation after transmission, and most plant diseases may have multiple infestations in one season.
8. The spread of the pathogenic pathogen inoculum spreads outward from the infestation source. Most pathogens can be transmitted by means of air currents, currents, mediators (insects, mussels, fungi), soil and humans.
9. The degree of morbidity includes morbidity and severity. The morbidity generally refers to the percentage of diseased fields, plants or organs, and the degree of severity refers to the degree of damage to the plants or organs in the field.
10. Plant disease control uses the cybernetics principle to select the optimal disease management method to maintain the control of plant diseases below the level of economic damage. At present, for the treatment of diseases, the principle of prevention, comprehensive prevention and control, and promotion of ecological governance are mainly adopted. It may mainly adopt plant quarantine (regulatory control), agricultural control, disease resistance breeding, chemical control, and biological control to control the occurrence and spread of diseases.
Lycium sweet nature, Ping, owned by the liver and kidney, with nourishing liver and kidney, Liver eyesight effect, often with Rehmannia, chrysanthemum, yam, cornus and other drugs with the use. Modern medical research shows that it contains the carotene, betaine, vitamin A, vitamin B1, vitamin B2, vitamin C and calcium, phosphorus, iron, etc., with increased white blood cell activity and promote hepatocyte regeneration pharmacological effects of modern pharmacological experiments show that: Wolfberry has enhanced immune function, inhibition of tumor, lowering blood sugar, lipid-lowering, anti-fatigue and other functions. "Materia Medica remarks," that medlar can make "gas can be filled, blood can make up, Yang can be health, Yin can be long, rheumatoid can go, there are ten wonderful Yan."
