Prevention of rot disease in yellow pineapple seedlings

Yellow pineapple also known as Phellodendron, for Rutaceae deciduous trees, dry bark medicine, spleen and diarrhea, heat dampness, detoxification and antibacterial effect, attending hot and humid diarrhea, fever, fever, toxic heat eczema embolism. Phellodendron communis is a woody plant of Rutaceae and its application site is the skin. It causes the death of plants during the collection process. The renewal cycle needs more than 20 years. Therefore, the medicine of Phellodendron przewalskii has always been in short supply, especially in recent years, the development of Phellodendron amurense in various countries in the world. Due attention has been paid to a large number of fellings in the production areas and Phellodendron has entered the endangered state. Therefore, Huang Bo has been listed as a key Chinese herbal medicine for key development by the State Administration of Medicine. In the process of Phellodendron seedlings, some of the seedlings showed leaf wilting, and finally the whole plant died. After the diseased plant was pulled up, it was found that the roots were black and rot, which was caused by the rot disease caused by Fusarium. 1. In the early stages of symptoms, the roots of the diseased plants were water-stained, and the later roots were black and rot. The roots were rot and died and they could not absorb the water and nutrients and eventually caused the whole plant to die. 2. Causes of morbidity Due to the increased viscosity of the nursery soil for many years, the air permeability deteriorates, the acidity of the soil increases, a large number of anaerobic bacteria grow, the respiration of the plant roots decreases, and the absorption of nutrients and mineral ions weakens, making the plant resistant. The disease is reduced, and the soil-borne pathogens enter the roots of plants, destroying the tissues in the roots of plants, and preventing the physiological activities of the roots. Causes roots to rot and eventually causes the death of the entire plant. 3, prevention and control First, the choice of land to choose flat, fertile, good drainage, strong permeability of sandy loam soil, keep the seedbeds well drained, strong permeability to prevent the breeding of anaerobic bacteria. The second is to use lime soil to disinfect the soil and adjust the pH of the soil. The third is to apply potash fertilizer such as plant ash to enhance the disease resistance of plants. The fourth is intercropping, rotation, and intercropping. Fifth, it was found that the diseased plants were immediately removed and destroyed, and the diseased areas were disinfected with lime. A total of 600 times liquid of 50% tetrazine was used to completely disinfect the ward to prevent the disease from spreading. (Source: Lizhuozhou
