1. Seedlings: The northern regions are generally planted in the spring, and improper winter planting in autumn planting is prone to freezing damage. When planting seedlings, fill in some wet acid charcoal soil or pre-formed planting soil in the small pit, then plant the seedlings and spread the roots, so that the added mixed charcoal soil is surrounded by the seedling roots, and finally the soil is covered. To the ground level.
2, surface coverage: after planting, on the spot, the surface of the planting hole is covered with a layer of straw, humus soil, bark, wood chips, etc. or sprayed with a new high-fat film , which can adjust the ground temperature, prevent surface water evaporation, and maintain Soil moisture and promotes root growth.
3. Fertilization: Blueberry is a plant that is sensitive to fertilizer. Excessive fertilization will damage the root system due to excessive soil base concentration and cause plant death. It can be replaced with a pollution-free cationic active agent to promote Huawang No. 2, and promote the flowering gene to make the fruit trees more flowering and more fruit. In the young fruit period, timely spraying the strong fruit tingling to increase the nutrient delivery.
4, winter protection: Although short bush blueberry and half-high bush blueberry cold resistance, but still have freezing damage. The most important manifestations are overwintering and flowering buds, which can cause all parts of the ground to freeze to death in special years. Therefore, in the cultivation of blueberries in cold regions, winter protection is also an important measure to ensure production. For example, piles of snow and cold, trees and trees to protect the generals .
