Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a method for raising seedlings of ginkgo trees. Background technique [0002] Ginkgo is a deciduous tree of Ginkgoaceae and Ginkgo, also known as ginkgo, gongsun tree, duck foot tree, and cattail leaf fan. Ginkgo biloba is the oldest relict plant among the extant seed plants. All other plants of the same class as it are extinct, known as living fossils. Ginkgo biloba was born hundreds of millions of years ago, and the surviving ginkgo trees are rare and scattered. Old trees over a hundred years old are rare. Variations and varieties include: yellow leaf ginkgo, tower ginkgo, split ginkgo, weeping ginkgo, variegated ginkgo, etc. 26 species. Ginkgo is full of treasures, people have a large demand for ginkgo, and ginkgo trees are prone to acclimatization in the process of planting, and the survival rate is not high, which brings direct economic losses. Contents of the...
