Blueberry Spring Management
I. Remove the cold soil in due course. Due to different climatic conditions in different regions, the time for removing cold-resistant objects varies. The timely removal of cold soil can promote blueberry germination, germination, and robust growth. Precaution can not be removed too early, prematurely low temperature, spring wind, the root can not absorb water and nutrients, germination of flowers, leaf buds, will gradually dry out after the expansion of the dead, but also vulnerable to late frost damage; late spring temperature rise The rapid change, the increase in temperature and humidity in the mound will cause the buds of flowers and leaves to germinate in the soil, and may even cause yellowing of tender shoots. The unripe stems and leaves will not withstand the wind and sunlight.
Second, timely irrigation (drip irrigation) return to Qingshui. How much wind is dry in the spring, after the soil is removed, it is a critical stage of blueberry sprouting. The adequate watering of green water can ensure that the blueberry germinates normally and the branches and buds are full, and the blueberry shoots can also be prevented from draining. Should be based on different plots, different environments, pouring or returning to Qingshui.
Third, a reasonable pruning of the tree. In order to ensure robust blueberry trees and ensure late yield, blueberries are 2-3 years old and young trees are pruned to remove all flower buds in order to promote root development, the expansion of the canopy and the increase in the number of shoots, laying a good foundation for early high yields. For 4-5-year-old saplings, the canopy is still mainly expanded, but a small amount of results may be appropriate to sparsely thinning fruit and removing mechanical damage and diseased branches. More than 6-7 years of age, the blueberry plants are easily degraded. At this time, the pruning is mainly to improve the light conditions, to eliminate the dense branches, cross branches, overlapping branches, diseased branches, thin and weak branches and pest damage branches, when the age is too old To timely retract and update, weak twigs can be trimmed using buds and flowers to make them strong.
