Plan hoe in time to improve soil permeability
In the near future, the watering interval can be appropriately extended, and the areas with signs of wilting can be timely cut and hoeed. The depth should be about 5 cm to 6 cm to accelerate the loss of soil water, improve soil permeability, and improve soil physical and chemical properties. Hoe it again after 2 to 3 days to allow the soil to fully dry and promote the germination and growth of new roots.
Treatment of planting holes
Plants that have died should be removed in time, taken away from the plot, and buried deep for destruction. Then disinfect the planting hole and the surrounding soil with quicklime. You can also spray the planting hole with phosphaluminum, mexamethazine and other agents. Fill each hole with more than half a catty of medicine to ensure that the soil in the hole is soaked to achieve a sterilization effect and reduce the spread of pathogens with water. Possible.
Root irrigation
Use metalaxyl·fludioxonil + fluazinam + Zhongshengmycin to irrigate the roots of diseased plants in time. In order to avoid root damage, rooting agent can be added to the medicinal solution to maintain the root system and improve the root system. The role of resistance. Do not use too much of the root irrigation agent, otherwise it will cause the soil to have poorer air permeability, which will make it easier for pathogens to infect and aggravate the occurrence of dead trees. After the soil moisture is suitable, it can also be used with water to spray hymexazol or metalaxyl mancozeb. In fine weather, spray orange bright or copper preparations on the leaves to prevent bacterial diseases to prevent the development of diseases.
Use of chemical agents and microbiological agents
To prevent root rot, chemical agents have the characteristics of rapid sterilization, quick onset, and stable effects. However, frequent use of drugs is prone to drug resistance, while microbial agents have a long-lasting effect and are safe to use. Therefore, it is recommended that the two agents be used alternately, which can complement each other and enhance the effect of preventing root diseases.
