How to deal with the disease of pepper?
Zanthoxylum bungeanum is mainly distributed in Sichuan, Shaanxi, Henan, Hebei, Shanxi, Yunnan, Gansu and other provinces. Although the yield per mu of pepper is not low, the tree is prone to gum disease, which has become one of the main bottlenecks for the healthy development of this industry. . Why does pepper have a gum disease, and what is the prevention and treatment of pepper juice? Let Xiaolin of Huinong.com tell you!
   Why do peppers get gum disease?
According to the survey, the incidence of gum disease in the Zanjiao Park, which is extensively managed and debilitated, can reach 75-90%. The disease begins to attack at the seedling stage and is more common in adulthood. The yellow mucus flows out from the main tree of the pepper tree, and gradually increases to become a yellow-brown gelatin, so it is called a gum disease. The pepper tree that is harmful to the disease first died from local death and then spread to the death of the whole plant. Glue disease seriously weakens the tree and affects the yield, quality and plant life, which is the main problem of pepper production.
Flow gum disease is severe in high temperature and high humidity environment. It can be divided into two types according to different causes: invasive flow glue (caused by fungi, two peaks in one year, the first time from May to June, the second time 8 - September) and non-invasive flow glue (due to mechanical damage, insect damage, injury, frost damage, burns, etc. caused by improper fluid flow and mismanagement, the season is severe with heavy rain in July-October).
In addition to the fungal infection and the presence of wounds (human manipulation, pests, bad weather), the tree is weak, the age is large; the fertilization is unscientific, the nitrogen fertilizer is too much, the medium and trace elements are insufficient; the high temperature and high humidity, the rain is more; Improper, poor ventilation and light transmission; soil compaction, viscosity, etc. are easy to cause gum disease.
Zanthoxylum gum disease prevention and treatment method
1 Strengthen the cultivation and management of trees and enhance the disease resistance of trees. Appropriately reduce the use of nitrogen and phosphate fertilizers, and increase the application of organic fertilizers, biological bacteria and trace elements. Traditionally planted, too much nitrogen and phosphorus fertilizer has been applied to the soil to cause curing effects on trace elements such as potassium, calcium and magnesium in the soil. The application of organic fertilizer, biological bacteria and medium and trace elements can effectively improve soil aggregate structure and alleviate soil compaction problems while supplementing nutrients. Since some pests mainly invade from the wound, it is necessary to timely root and control the underground pests and diseases, avoiding damage to large roots and reducing non-invasive diseases during deep-turning operations.
2 timely spraying, early prevention and treatment. For parks with serious pests, it is necessary to kill pests in time. For those who are prone to disease spots, it is necessary to scrape the lesions in time, and then apply the original liquid protection of "Jiefuling". For the gum trees or weak trees, use the "green dead"å…‹"150-300 times + "garlic oil" 1000 times + "Wofeng Su" 600 times irrigation, the effect is good. At this stage, the transpiration of the pepper tree is not large. The medicine can block the wound and repair the damaged cells. The damaged part will grow a new bast, and it can provide a large amount of nutrients needed for fruit tree growth, supplement nutrition and promote Growth, reducing the chance of infection of the bacteria and the occurrence of glue.
3 reasonable trimming, control production, avoid large and small years
Reasonable pruning is a prerequisite for the high yield of pepper trees. By pruning to form a certain high-yielding tree shape, timely remove the pests and diseases, reduce the chance of secondary infection, rationally arrange the branches, control the results, overcome the years and years, make the tree strong, and achieve high yield, high yield and stable production. After pruning or man-made operation, use 200-300 times spray of "Jiefuling" in time to accelerate wound healing, block the pathogens, and effectively prevent gum disease, sterilization and nutrition, and improve tree resistance.
4 After picking, when the leaves are falling (like the leaves do not fall leaves), spray the medicine in time to repair the wound and prevent freezing.
Use "Breakfast" 200-300 times liquid + "Wofengsu" 600 times + silicone, sprayed once a whole plant, for comprehensive sterilization. Sterilize and repair fruit marks, leaf marks and wounds caused by agricultural operations, prevent bacteria from invading the body; supplement nutrition, promote wound healing, improve frost resistance and reduce the occurrence of diseases.
5 Qingyuan disinfection, reducing wintering pathogens
In the winter, the pepper garden should be thoroughly cleaned, and the branches and leaves of the pests should be burned or buried deeply; sprayed once in the early spring and late autumn to prevent wintering diseases; before winter, the trunks are painted white to prevent freezing damage.
Tips:
At present, many parks also have coal pollution, which seriously affects the photosynthesis and respiration of crops. The use of "é“果安" 300 times + "garlic oil" 800-1000 times spray-dried, spray 1-2 times can effectively solve the coal pollution The problem is to let the leaves and branches see the sun again.
