Method for performing winter protection on outdoor blueberries

Abstract

The invention discloses a method for performing winter protection on outdoor blueberries. The method comprises the following steps of (1) firstly placing one side of a white plastic film at the bottom of a furrow of a blueberry tree; (2) covering a plant with the white plastic film to prevent flower buds from being damaged, pressing the other side of the white plastic film with soil, and burying two sides of the white plastic film into soil to prevent acceleration of aging; (3) covering the white plastic film with a sunshade net, and pressing two sides of the sunshade net with soil. The method has the beneficial effects that the outdoor blueberry plant is directly covered by the white plastic film and the sunshade net so as to realize winter protection; the method is simple and feasible; the cost is low; furthermore, the white plastic film and the sunshade net can be repeatedly used for more than 3 years; meanwhile, the sprouting rate of the blueberries is reduced, and the blueberry benefit is enhanced.

Description

technical field [0001] The invention belongs to the technical field of digital cultivation, in particular to a cold-proof method for open-air blueberries. Background technique [0002] Blueberry trees are shrubs with thin branches, thin xylem, underdeveloped waxy layer and cuticle, and weak water retention capacity. Under the action of low temperature and strong wind in winter, it is easy to cause damage to stripping, which has become the main bottleneck for the development of the blueberry industry in the north. , especially in varieties with low cold resistance such as Lanfeng. Although the effect of burying cold protection is good, it is most commonly used in low bushes and half-high bushes to protect against cold. However, high bush blueberry trees are strong, and the main bushes are not easy to fall when buried in the soil, so the effect is not ideal. Cold-proofing materials for bush blueberries is imperative. Contents of the invention [0003] The purpose of the pr...
