Cold-proof method for peony trees

Abstract

The invention discloses a cold-proof method for peony trees. The method comprises the following steps that peony plants which need cold-proof are gathered tightly by using a rubber band, then are wrapped with two layers of newspaper, tightened with rubber bands, finally wrapped closely with a cold-proof blanket and tightened with rubber bands, wherein a connector of the cold-proof blanket ought to be located on the lee side, and the position where the cold-proof blanket makes contact with the ground is covered with soil and trodden down. In the method, the materials are simple and easy to obtain, easy to operate and capable of being reused, and the cultivation cost is reduced; the method can be flexibly improved according to the type of the peony trees and the cultivation mode, it can be ensured that the peony trees of various types safely pass the winter and normally bloom in the Northeast China Region, the use range is large, the technology is normalized, popularization is easy, and technical supports are provided for the popularization of the peony trees in the Northeast China Region, the development of the peony industry, especially the resolution of the problem that paeonia suffruticosa andr cannot pass the winter in cold areas of the Northeast China Region, and the extension of the peony industry chain.

Description

technical field [0001] The invention relates to the fields of agriculture and flower and tree cultivation, in particular to a method for preventing cold of peonies. Background technique [0002] The cold climate in winter in Northeast China is an important factor affecting the survival and promotion of peonies in Northeast China. At present, most peony varieties in Northeast China need artificial cold protection to survive the cold winter. Peony winter cold protection technology is the key to ensure that peonies can be promoted in Northeast China measure. [0003] At present, there is no clear and systematic operation specification for the artificial cold protection measures of peonies in Northeast China. The methods used are complicated to operate, the cold protection effect is poor, and the cold protection materials used are chaotic, and most of the materials used cannot be recycled, which is easy to pollute the environment and cannot be cultivated on a large scale.

[0003] At present, there is no clear and systematic operation specification for the artificial cold protection measures of peonies in Northeast China. The methods used are complicated to operate, the cold protection effect is poor, and the cold protection materials used are chaotic, and most of the materials used cannot be recycled, which is easy to pollute the environment and cannot be cultivated on a large scale. Application, arbitrary cold protection measures caused a large number of peonies to freeze to death, seriously affecting the popularization and application of peonies in cold regions, and restricting the publicity effect of peonies as the national flower
