Highbush blueberries winter-proofing method

Abstract

The invention relates to a high-bush blueberry winterproofing method. The method is as follows: 0.12mm of black plastic film is made into a cylindrical strip with the diameter to be 450mm; the strip is cut off according to the tree height when in use, when autumn changes into winter, the blueberry branches are bunched by nylon ropes from bottom to top firstly, then the blueberry branches are sheathed with a cut plastic cylinder, the lower part of the cylinder is contacted with the pre-leveled ground and folds 10-15cm outwards, and is compacted with earth; an opening at the upper end of the plastic cylinder is tightened by the nylon ropes, finally, a layer of straws is wrapped outside the plastic from bottom to top, then tightened by the nylon ropes. In the next spring, the straws and the film are removed from the trees before flower buds sprout, collected, stored in a place away from light and rain for reuse in the next year. The method has the beneficial effects that the black film is low in light transmittance, and plays the roles in heat insulation and moisturizing, and the straws bunched outside can regulate the change of diurnal temperature, thus ensuring the wintering safetyof blueberries, and the cost is lower.

Description

A cold-proof method for highbush blueberries Technical field The invention belongs to the technical field of tree cultivation, and relates to a cold-proof method for highbush blueberries, which is suitable for the cultivation of highbush blueberries in northern regions. Background technique The winter in the northern region is extremely cold, dry, and windy. Some tree species that are not very cold-resistant suffer from freezing damage or physiological drought from winter to early spring, commonly known as pumping. Make local branches withered, which can cause damage to some branches of the tree in light cases, and cause the death of the whole tree in severe cases. Blueberries are native to North America, and rely on snow to keep out the cold in their natural state. There is little snow in winter in the northern part of our country, and it is easy to wither shoots when exposed to the air naturally. A large number of flower buds wither and fail to harvest in the next year,...
