A kind of antifreeze method of ginkgo saplings

Abstract

The invention relates to an antifreezing method for ginkgo tree saplings. The antifreezing method for ginkgo tree saplings comprises the following steps: S1, ginkgo tree leaf surface and branch antifreezing treatment: lopping ginkgo tree saplings; S2, spraying an antifreezing agent to ginkgo tree leaf surfaces and branches at the air temperature of 0-5 DEG C; S3, repeatedly spraying the antifreezing agent for three times at an interval of 10-12 days; S4, ginkgo tree trunk antifreezing treatment: enabling the positions, which are away from the ground by 1 m, of the ginkgo tree saplings to be coated with a whitewashing agent uniformly; S5, adding antifreezing sleeves on parts whitewashed in the S4; S6, ginkgo tree root antifreezing treatment: artificially furrowing the outer peripheries of roots, and filling antifreezing water; and S7, covering real-time antifreezing layers with the upper part of the soil subjected to antifreezing treatment in the S6, and covering the real-time antifreezing layers with weakly acidic humic soil. By adopting the method, level-to-level antifreezing treatment on various parts of ginkgo trees can be realized, particularly, the real-time antifreezing layers are arranged on the outer peripheries of the roots so that an efficient and continuous antifreezing effect can be achieved, the soil can also be improved effectively by using the surface layer humic soil, and the antifreezing effect and antifreezing time are guaranteed better.

Description

technical field [0001] The invention relates to the field of seedling planting methods, in particular to a method for preventing freezing of ginkgo seedlings. technical background [0002] Ginkgo tree is also known as ginkgo tree, also known as duck foot tree or gongsun tree. It is one of the most precious tree species in the world, and it is the only species of ancient ginkgo plants that survived on the earth. Therefore, botanists regard it as a "living fossil" in the plant world, and it is associated with cedar, araucaria, and golden pine. Together, they are known as the world's four largest garden trees. Chinese horticulturalists also often compare ginkgo with peony and orchid, and call it "three treasures of gardens" and respect it as a national tree. During the planting process of ginkgo trees, antifreeze in winter has always been a concern of people.

Problems solved by technology

During the planting process of ginkgo trees, antifreeze in winter has always been a concern of people. Because the winter in the north is severe and lasts for a long time, it is a severe test for the wintering of ginkgo seedlings. In the traditional process, People also realize the antifreeze of the trunk by wrapping straw or plastic cloth at the trunk, and also by spraying antifreeze to prevent freezing, but in the face of continuous cold weather, the effect of antifreezing is not good, and many ginkgo seedlings appear after the severe cold death phenomenon
