The freezing disaster in mid-January of 2008 caused the Yangmei County in resource counties to suffer a lot of losses. Some of them were uprooted and their branches were severed. After the disaster, scientific management must be strengthened to restore the fruit tree as soon as possible. The following technical measures should be adopted.

1, down the tree and the treatment of broken branches. The crushed snow on the broken branches should be promptly sawn at the broken end, coated with a bactericide to facilitate the healing of the wound. The broken branches should be fastened with plastic ropes as soon as possible, and the fallen fruit trees should be covered with soil immediately.

2, pruning. Yangmeishu is mainly composed of happy hearts. The combination of pruning techniques and topping is carried out. Without affecting the ventilation and light transmission, the lower and inner weak branches should be kept as far as possible. Avoid “cutting without cutting, cutting without cutting outside”.

3, a reasonable fertilization. (1) Saplings should be given less nitrogenous fertilizer and more phosphorus and potassium fertilizers to promote new shoots and expand the canopy. (2) Result tree. For the first time in May-June, the plant applied 50-80 pounds of composted manure or biogas slurry or 3-4 pounds of compound fertilizer, and the second time in July-August, the plant applied 8-10 pounds of tree ash or compound fertilizer 4- 5 pounds, in October fertilization mainly farmyard manure, barrow manure 50 pounds plus cake fat 4-5 pounds.

4, to strengthen the prevention and control of pests and diseases. Bayberry mainly damages leaves of brown spot, and it sprays thiophanate-methyl or carbendazim once a month in the middle and middle of May. 80% dichlorvos or pyrethroid pesticides can be used to control pests such as chafer and leaf roller moth.
