Problems solved by technology

At present, the methods of cultivating ginkgo seedlings mainly include sowing, cutting and grafting, etc., but these methods mainly have the following prominent problems in actual production: in the nursery where ginkgo seedlings are sown and raised, there are usually some trunks that are bent, mechanically damaged, or severely damaged by diseases and insect pests. Seedlings, the economic value of this part of seedlings is low, especially in landscaping
Also do not see the report of ginkgo seedling stubble rejuvenation at present, the present invention proposes under such technical background

Embodiment 1

[0018] Applying this method is carried out in the ginkgo germplasm resource nursery of Shandong Agricultural University Forestry Experimental Base in Tai'an City, Shandong Province. The seedlings with trunk bending, mechanical damage and pest damage are implemented to be stubbled. Retain the straight, vigorous and well-growing complex stems to replace the mother stems to achieve the rejuvenation effect. The implementation steps of the ginkgo seedling stubble and rejuvenation method are as follows:

[0019] 1. Preparation for stubble and rejuvenation of ginkgo seedlings

[0020] Tool preparation: pruning shears, vigorous pruning shears.

[0021] Selection of seedlings for rejuvenation: select seedlings with bent trunks, mechanical damage, or serious damage from plant diseases and insect pests in the nursery as the objects of stubble and rejuvenation, and mark them.

[0022] 2. Selection of stubble time

[0023] After the leaves of the ginkgo seedlings fall, the stubble can b...

Abstract

The invention discloses a stumping rejuvenation method for Ginkgo biloba L. nursery stocks. A stumping method is used for rejuvenating nursery stocks with bent trunks, mechanical damage and pest and disease damage, so that the quality of the Ginkgo biloba L. nursery stocks is improved, and production requirements are met. The characteristic of high tiller sprouting performance of Ginkgo biloba L. is utilized, trunks are stumped from stem bases to promote the growth of branches, and the branches and the trunks are straight and high in growth speed, so that the value of the nursery stocks is improved. The method is used for rejuvenating the Ginkgo biloba L. nursery stocks, and the operation is easy and feasible.

Description

technical field [0001] The invention belongs to the technical field of tree growth and propagation, in particular to a stubble and rejuvenation method for ginkgo seedlings. Background technique [0002] Ginkgo biloba L. is a relic plant of Quaternary glaciers, and a rare tree species with excellent leaves and fruits. 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 very likely to be selected as the "national tree" of our country because of its extremely high economic, ecological and cultural value. At present, the methods of cultivating ginkgo seedlings mainly include sowing, cutting and grafting, etc., but these methods mainly have the following prominent problems in actual production: in the nursery where ginkgo seedlings are sown and raised, there are usually some trunks that are bent, mechanically damage...
