The continuous rains in July and August brought serious losses to the jujube farmers in Zhangzhou, Hebei. According to Xiao Jialiang, chief of the forestry station of the city's forestry bureau, it was discovered in the field survey that, due to the impact of continuous rainfall in the near future and the improper response of the jujube farmers, the jujube tree fell more heavily this year than in previous years, and some jujube trees may cause outbreaks.
According to reports, the number of pests that damage leaf and fruit in this year is more than in previous years. At the same time, excessive air humidity also causes anthrax and pulp rot to occur in advance.
In order to reduce losses, Xiao Jialiang's headmaster proposed countermeasures to the jujube farmers in the main producing areas of red dates: After sunny days, they should timely cultivate the loosened soil; the accumulated water jujube garden should be drained in time to improve the permeability of the soil. At the same time, under the tree to clear the germination of new sprouts in the ground, the tree cut off the excess leggy branches, ventilation, light transmission, accumulation of nutrients, reduce the loss of young fruit, and promote fruit growth. At the same time, naphthalene acetic acid can be properly sprayed to prevent fruit drop. According to the characteristics of jujube rust, anthrax, and rotten fruit disease that occur early this year and the severity of the disease is heavy, spraying the fungicides once every 7-10 days after a sunny day protects the trees, leaves and fruits. At the same time spraying 0.5% potassium dihydrogen phosphate mixed with trace elements foliar fertilizer or other foliar fertilizers once, to supplement the tree's demand for nutrients.
