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 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. According to the calculation of planting 330 plants per mu and the height of the tree 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 ...

Abstract

The invention relates to a method for winter protection of trees by utilizing an aluminum plating reflective membrane. For the winter protection of gardening shrubs such as highbush blueberries and the like and arbor young trees, the aluminum plating reflective membrane used as a winter protection material is made into a tubular bag with proper length; during end-autumn and early-winter, tubular bags are sleeved outside tree bodies of which branches are bound into fasciculation by nylon cords in advance, and then are tightly bounded and sealed; for the winter protection of shrub-like trees such as lowbush blueberries and the like, vine plants such as grape vines and the like, and nursery-grown plants, the aluminum plating reflective membranes are directly covered above the plants, the planted row and a seed bed with necessary winter protection, of which branches are bound in advance, and the aluminum plating reflective membranes are compacted around by soil; and for the prevention of frost crack of trunks of planting tree species, the aluminum plating reflective membrane covers 1 to 2m from the bottom of the trunk. The method has the advantages that: 1, damage to trees caused by overhigh local temperature and overlarge temperature difference between day and night of the trunk due to direct solar irradiation to the day side of the tree is avoided; and 2, the bag covering mode has the effects of heat insulation and moisture resistance, and the method is low in cost and can be easily operated.

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...
