Embodiment 1

[0022] This technique was used to test the main and side branches of young and middle-aged ginkgo in Yiyuan County, Shandong Province, and Taixing City, Jiangsu Province. The wounds healed one year after artificial incision induction, and the incisions began to protrude downward after two years. The milk is obvious and the trees grow well. The method implementation step of artificially inducing ginkgo biloba mammary gland formation is as follows:

[0023] 1. Preparation of artificially induced ginkgo biloba

[0024] The prepared tools include: grafting knife, sterilized paper, and special plastic film for binding. Before artificial induction, cut the paper sheet into long strips with a width of 1.0cm-2.0cm and a length of 2.0cm-4.0cm, and wrap it in kraft paper for autoclaving. It can be taken and used during artificial induction.

[0025] 2. Preparation of induced seedlings or saplings

[0026] Choose 5-50-year-old young and middle-aged ginkgo seedlings or saplings with go...

Abstract

The invention discloses a mastoptosis-shaped burl forming method of ginkgo trees by artificial induction. 5-50 years old, strong-root, healthy and pest-free ginkgo trees are used as experimental materials, the mastoptosis-shaped burls of the ginkgo trees are obtained by a carving method so as to meet requirements of academic researching and viewing. According to the ringing and girdling technical theory, downward delivery of organic nutrition (photosynthate) is prevented, nutrition level of branch above wounds is increased, and downward growth of tree trunks is stimulated by nutriment accumulated at the wounds so as to form burls which further grow to be mastoptosis-shaped burls. The mastoptosis-shaped burl forming method has a remarkable effect on inducing to form the mastoptosis-shaped burls, and is easy to operate and feasible.

Description

(1) Technical field [0001] The invention relates to a method for artificially inducing the formation of ginkgo weeping milk, and belongs to the technical field of tree growth and reproduction. (2) Background technology [0002] Ginkgo biloba L. is the oldest relict plant among the existing seed plants. It is a historical heritage and living fossil, a rare tree with unique structure and excellent fruit and material, and a milestone to reveal the mysteries of nature. As the largest ginkgo country in the world, China has more than 90% of the germplasm resources of ginkgo in the world, and the cultivation history in my country can be verified for thousands of years. Ginkgo biloba is a special germplasm in the ginkgo family. It has become an ideal material for research in many fields such as biology, ecology, botany, forestry, and horticulture. It has important ornamental and academic values. There is a folk saying about ginkgo "hanging breasts and hanging yang", which means "ha...
