1. Prevent diseases and insect pests early. Before germination and germination, use 800-fold liquid new high-fat film with 150-fold barium polysulfide for insect repellent, or use a tree protection general with a 3 to 5 degree stone sulfur mixture to kill eggs and overwintering bacteria. After leaf spreading, spray 500-600 times of new high-fat film to supplement nutrients and prevent disease.
Second, early application of germination fertilizer. Results Compounds of 0.75 to 1 kg were applied per plant for large trees, and 0.25 to 0.5 kg for each plant applied to small trees.
3. Stand up early and fasten the branches as soon as possible. Stand up as soon as possible, and finish the work before the leaves germinate. Standing upright, pulling the wire too late, it is easy to damage the young buds of kiwi. Kiwi orchards without tying vines should be tyled in time before germination. The basic technical essentials are: branches and branches are not covered with iron wire, branches and branches are tied, the branches should be evenly placed at equal distances, the branch distance is about 30 to 40 centimeters, non-overlapping, non-crossing, and not crowded, thick branches Tied into a horizontal shape, the mean branch is tied diagonally.
Fourth, shallow hoe, repair channels. After the beginning of spring, the temperature rises quickly, which is unfavorable for the growth of the awakening kiwi root system. Because the surface water evaporation continues to increase, after the spring, the kiwi orchard should be shallowly hoeed and raked to promote the orchard to maintain moisture and repair the irrigation and drainage channels.
5. Prevent frost damage early. At the early stage of sprouts, always pay attention to frost. Water the orchard before frost arrives, spray new high-fat film in time to prevent frost, smoke the ground, whiten the tree body, and spray the tree general to prevent late frost.
