Problems solved by technology

[0002] The technical shortcomings of the existing overwintering of the whole plant of Populus chinensis: 1. Populus chinensis cannot safely survive the winter when planted in major cities in the three northeastern provinces. It only relies on artificial cold protection. In mid-October in autumn, corn stalks are used to bundle and weave hedges around the trees. Erection of wind barriers higher than plants
Frozen dead branches need to be cut off, otherwise it will affect the viewing, time-consuming and labor-intensive
3. There is no special cold and antifreeze agent for Populus sinensis
Therefore, it is difficult to popularize and plant Populus sinensis in Northeast China
The younger the tree is, the worse the resistance is. Although the cold resistance is improved when the tree is older, the transplanting cost is high, so the application of Populus sinensis in the north is less

Embodiment Construction

[0009] A kind of cold-resistant and overwintering method for the whole plant of the annual Chinese Red Leaf Populus, the raw materials include: abscisic acid, clear water, the English abbreviation of abscisic acid: ABA, and the chemical formula of abscisic acid is: C 15 h 20 o 4 ; (2) Preparation: Mix the two substances at 0.03% by mass: take 0.3 mg of abscisic acid crystal powder and add 1000 ml of water, and mix well; (3) Specific implementation steps: before the dormancy of Populus sinensis in early September Spray the preparation obtained in step (2) on the whole leaves with a mist applicator. After 15 days, spray the preparation obtained in step (2) on the whole leaves once with a mist applicator. In October, apply the preparation obtained in step ( 2) The obtained preparation is sprayed on the whole plant again with a mist applicator to complete.

Abstract

The invention relates to a method for enabling whole annual Chinese Hongye poplar to resist coldness and overwinter. The method comprises the following steps of: adding 1,000ml of water into abscisic acid and mixing uniformly; spraying the obtained preparation on leaves of the whole Chinese Hongye poplar by using a mist sprayer before the Chinese Hongye poplar hibernates at the beginning of September; spraying the obtained preparation by using the mist sprayer once again after 15 days; and spraying the whole Chinese Hongye poplar in October. By the method, the coldness resistance of the Chinese Hongye poplar can be improved, the phenomenon that all branches of the Chinese Hongye poplar on the ground are frozen to death after the winter is avoided, and the aim of enabling the whole annual Chinese Hongye poplar to overwinter safely is fulfilled.

Description

technical field [0001] The invention relates to a method for preventing cold and overwintering by using the whole plant of the annual Chinese Hongye Populus. Background technique [0002] The technical shortcomings of the existing overwintering of the whole plant of Populus chinensis: 1. Populus chinensis cannot safely survive the winter when planted in major cities in the three northeastern provinces. It only relies on artificial cold protection. In mid-October in autumn, corn stalks are used to bundle and weave hedges around the trees. Build a wind barrier higher than the plants. Or roll it up with straw rope, and wrap the trunk and branches with straw to keep out the cold. 2. Overwintering without protection from the cold, all the aboveground parts will freeze to death and form dead branches. In the second spring, the dead branches will be cut off and germinate from the roots to form large shrubs without trunks. It is difficult to form tall trees, and new branches will b...
