After an orchard is hit by a hailstorm, the farmers should do it.
Recently, Baishui County in Shaanxi Province suffered hailstorms lasting about one and a half hours. About 30,000 mu of agricultural and economic crops such as apple and corn were severely damaged. Many disaster-damaged orchards and corn fields almost ended. After the orchard was hit by the hailstorm, the fruit farmers should pay attention to what they managed. The reporter interviewed Ma Zhifeng, a professor at the Yangling Vocational and Technical College. He said that after the orchard was hit by the hailstorm, it was a foregone conclusion that the income of the fruit growers will be damaged this year. The current priority is to adopt the following: Ways to ensure the normal growth of fruit trees next year.
Timely spraying
After the hail disaster, the orchards are damaged by leaves and fruit. At this time, the fruit growers should immediately spray pesticides on the orchards and spray the medicine to select protective fungicides to prevent the early defoliation and fruit diseases in the orchards after the leaves have been damaged. Leaving the leaves of fruit trees will adversely affect the results of the orchard next year.
In addition to the damage of the leaves, if the hailstone is severe, there will be many wounds on the front of the fruit tree branches. Therefore, in the process of spraying, fruit growers must also play protective fungicide for the fruit tree branches to prevent hail damage from causing secondary leaf and fruit diseases of fruit trees, as well as aggravation of late rot disease.
Excluding residual fruits without commodity value
For the fruits damaged by hail, Professor Ma Zhifeng reminded the farmers that they must directly remove the fruits that have suffered serious damage and have no commercial value. They can be sold to the juice factory after picking. If the fruits without commodity value are not removed, these fruits will continue to consume the nutrients of the tree and affect the flower bud differentiation of the tree. If the leaves are damaged, the burden on the tree will be extremely detrimental to tree growth. And for the slight damage, for example, only the small pits above, the value of the fruit can continue to retain the fruit.
Do not trim
After the hail disaster, whether or not the fruit trees can be trimmed, Professor Ma Zhifeng made it clear that do not trim during the growing season. After the hail strikes, the wounds on the tree body are many. If the fruit grower chooses to trim at this time, it will cause new wounds, which is not conducive to tree growth.
Spraying foliar fertilizer
After suffering hail disaster, the leaves of fruit trees were damaged and photosynthesis fell. Prof. Ma Zhifeng reminded fruit growers to pay attention to spraying foliar fertilizer on trees after the disaster in the orchard to increase the photosynthetic capacity of leaves. Because the root system has stopped growing at this stage, the nitrogen fertilizer is the main nitrogen fertilizer, adding a certain amount of urea.
Timely irrigation
Regarding orchard irrigation, Professor Ma Zhifeng stated that because of the hailstorm, the transpiration of the damaged fruit trees has increased, and the orchards have been arid. Therefore, fruit growers must pay attention to irrigation. In the irrigation process, pit irrigation should be adopted. A tree should be poured with one or two buckets of water, which is beneficial to the growth of the tree.
