1, scarifying and drainage
After the peach tree is flooded, loosen the soil and drain it in time. After rain, the soil will become very wet, the gaps in the soil will be filled with rain, and the roots will rot if they cannot absorb nutrients. At this time, it is necessary to turn over the soil in time to ensure that the roots can breathe enough oxygen.
2, sterilization and antivirus
After loosening the soil, the planted peach trees should be irrigated with microbial degerming agent or nail paste, so as to degerming the soil, reduce the breeding of pests and diseases, and restore the growth of peach trees as soon as possible.
3. Topdressing
In order to avoid the poor growth of peach trees after flooding, foliar fertilizer should be sprayed on the leaves in time, and brassin and iron and magnesium can be made into a mixed solution. Before fertilization, the fertilizer should be diluted with water to avoid excessive fertilizer concentration and leaf burns.
4, post-management
After the peach trees resume growth, the watering amount should be strictly controlled, so as not to let the soil accumulate water, and ditches should be dug and drained in time before the rainy season comes. In order to improve the yield of peach trees, it is necessary to apply decomposed liquid fertilizer to supplement nutrition every 10 day during the growing period. It is necessary to topdressing 1 ~ 2 times of decomposed organic fertilizer in autumn and winter to make peach trees survive the winter smoothly.
