In this long growing period, it is necessary to strengthen the management in order to ensure the continued high yield of alfalfa. At present, our province has entered the winter and the eucalyptus tree will enter dormancy. This period of management is the key to the next year's high yield. Now we introduce some winter management measures.

1. Clean the pastoral. In the winter, the garden will be fully cleaned, and the litter will be removed to reduce the damage of the next year. The litter can be buried deeply and used for beverages.

2. Winter trim. The pruning requirement is simple, and winter pruning is safer for eucalyptus than for pruning in spring and summer. The order of pruning is: cutting down the branches of the rhizomes, stems, main branches, internal axils, and crown apical branches along the canopy from the bottom to the top of the canopy, cutting them to a level, because they are pruned during dormancy, and the nutrients are stored in Branches, dry ducts, cut wounds naturally dry, do not hurt the tree. In the eucalyptus body, the buds that grow on the branches are cut off to prevent them from being freeze-dried or drained in the cold winter. Trimmed waste branches are collected, processed into feed, finely crushed and fed to livestock.

3. Strengthen winter field management. Litchi is sweet and has no odor. Sheep, rabbits or other livestock can easily feed into litchi. There must be people in Guanyuan, and do not let the animals enter the park to injure the trunk and ensure safe wintering.

4. Apply fertilizer irrigation. After ferrets go to sleep, fertilize. Apply 5 to 10 kilograms of fully-fertilized organic fertilizer per plant. Dig out the radiation ditches at 50 to 100 cm in the center of the trunk, or dig a round fertilization trough at the projection of the outer circumference of the canopy, 15 to 25 cm deep and 20 to 30 cm wide. , can not dig scar damage to prevent root rot. In the night when the soil is depleted and the ice is frozen, it is necessary to perform shallow irrigation and do not accumulate water. Normally, about 80 acres per acre are used to protect the earthworms safely.
