2. Planting. Seedlings can be sown in autumn or spring, ditches can be dug and deep ditches can be planted, all of which are 0.5 * 2.5-3.0m wide.
3. Leading. In production, single-wall fence frame, double-channel or single-channel wire binding and erection of columns are generally used. T-shaped scaffolding is suitable for autumn fruits and red berries.
4. water. Water raspberries in time after cultivation, but not too much or the roots will rot easily. Weeding is to prevent weeds and plants from competing for nutrients.
5, topdressing. Raspberry fertilization is mainly organic fertilizer, which can be carried out in spring and autumn; From mid-April to mid-May in spring, raspberries are put on shelves before germination; Fertilization in autumn is carried out after the fruiting mother branches are loosened and before the fallen leaves are frozen.
6. Plums. After harvesting the fruits in summer, cut off the branches with fruits at the base. After defoliation in autumn, before cold protection, cut off the basic branches, twigs, pests and diseases at the height of1.6-2.0m.. After 4 years, about 10 robust branches will be selected per meter to bear fruit. The number of branches is mainly determined by the number and density of these branches tied to the hedge next year, which can be judged according to the growth of seedlings, plant spacing, soil fertility and so on.
7. Cold protection. In winter in the cold areas of northeast China, it is generally necessary to bury the soil to prevent the cold, mainly to prevent the flower buds from freezing. Cover the branches tightly when burying the soil, and then bury the soil. Before cold protection, the cut rice branches of 1.6-2.0 shall be rolled, bound and covered in one direction. The next spring, when thawing, take out the cold-proof soil and tie it on the shelf.
