Problems solved by technology

[0003] Ginkgo trees can be used as economical trees or as landscape trees. Ginkgo trees are also used for greening in many places. When planting, they need to be raised first, and then transplanted. Now the survival rate of transplanted after seedlings is not high, only at 75- 85%, and it also requires complicated management to achieve, the cost of management is high, and transplanting with soil is often used when transplanting, resulting in a decrease in soil fertility in the seedling land and unsustainable development

Abstract

The invention relates to a method for planting ginkgo comprising following steps: (1) healthy ginkgo seedlings which are 1.5 to 1.8m high are selected, when the seedlings are lifted, the soil at the roots of the seedlings are soaked in potassium sulfate solution and then cleaned, and then the roots are soaked in nutrient solution for 12 to 15 h, wherein the mass fraction of the potassium sulfate solution is 0.65%; (2) well treated ginkgo in step(1) is transplanted, during transplantation, 1.5 to 3 kg peat soil is applied to each planting hole, soil covering is performed after planting, 100ppm vitamin A aqueous solution is used for irrigating and rooting. The planting method of the invention changes the traditional transplanting mode; original soil is no longer needed in transplantation, through multiple times of soaking treatments and the soaking and rooting with vitamin A solution, the survival rate of ginkgo transplanting can be substantially increased.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a planting method of ginkgo. Background technique [0002] Ginkgo trees grow slowly and have a very long lifespan. Under natural conditions, it takes more than 20 years from planting to bearing ginkgo fruits, and it takes 40 years to bear fruit in large quantities. Therefore, some people call it "Gongsun tree". The meaning of "Sun Deshi" is the old birthday star in the tree, which has ornamental, economical and medicinal value. China is not only the hometown of Ginkgo biloba, but also one of the earliest and most fruitful countries and regions in the cultivation, utilization and research of Ginkgo biloba. Throughout the ages, China has ranked first in the world in terms of ginkgo cultivation area and ginkgo output. Judging from the age of the existing ancient ginkgo trees, ginkgo was planted between the Shang and Zhou Dynasties in China. [0003] Ginkgo trees can be used as...
