Embodiment Construction

[0006] Below in conjunction with example the present invention will be further described:

[0007] For the cold protection of highbush blueberries, the aluminized reflective film is made into a cylindrical bag with a diameter of 450mm, and the length of the cylindrical bag is determined according to the height of the tree. From late November to early December, tie the blueberry branches with nylon ropes in order from bottom to top, then put them in bags with the reflective side facing outwards, and tie them tightly. Before the flower buds germinate in the next spring, the bags are removed from the trees in Dalian from late March to early April, and stored in a warehouse for repeated use in the next year. The reflective film can be reused for more than 5 years. If 330 plants are planted per mu and the tree height is 1.8m, the cost of each reflective bag is 4.0 yuan. If the average service life is 5 years, the cost of reflective film material is 262 yuan per mu per year. The la...

Abstract

The invention relates to a method for using aluminum-coated reflective film to protect trees from cold. For highbush blueberry and other shrub horticultural species and arbor saplings, the aluminum-coated reflective film is used as a cold-proof material to make a cylindrical bag with a suitable length. At the same time, put the cylindrical bag on the outside of the tree whose branches are bundled into bundles with nylon ropes, etc., and seal it tightly; for low trees such as low bushes, blueberries, grapes and other vines and seedlings for cold protection, aluminum-plated bags can be used. The reflective film is directly covered on the cold-proof plants, planting rows and seedbeds that have been bundled in advance, and the surrounding area is compacted with soil; for the tree trunks of arbor greening species that are cracked by frost, the lower part of the trunk is wrapped with aluminized reflective film at a height of 1 to 2 meters. The beneficial effects of the present invention are as follows: one is to avoid damages such as excessively high local temperature of the trunk caused by direct sunlight on the sunny side of the tree and frost cracks caused by excessive temperature difference between day and night; The method has low cost and simple operation.

Description

Technical field [0001] The invention belongs to the technical field of arboriculture, and relates to the prevention of freezing damage such as dry stems caused by physiological drought and tree trunk cracking caused by excessive temperature difference between day and night during the overwintering period of trees. The method of using aluminized reflective film to protect trees from cold is especially suitable for cold protection of garden trees such as blueberries and grapes and garden trees such as poplar and camphor in cold northern regions. Background technique [0002] Winters in the northern region are severe, dry, and windy. Some trees that are not too cold-resistant are prone to frost damage or physiological drought from winter to early spring. In mild cases, tree trunks may freeze and crack, and some branches may dry out. Strains die. This technology originates from the cold-proof technology research of blueberry. Blueberries are native to North America, and rely o...
