Embodiment 1

[0028] The present embodiment provides a method for breeding forest trees, the method comprising the following steps:

[0029] (1) Select different trees that can grow stably in heavy metal-contaminated soil in Xinxiang (Pashmina flounder, ginkgo biloba, paper mulberry, poplar, camphor, spruce, white elm, white bark pine, magnolia, cypress, locust, orientalis, juniper , Chinese locust and mulberry), to obtain seeds of different trees, the seeds were treated with 18% H before sowing 2 O 2 After disinfection treatment, soak in water for 5 hours, soak for 24 hours in an aqueous solution containing seed soaking agent (200mg / L gibberellin, 10mg / LBT rooting powder and 14mg / L 6-benzylaminopurine), wait for the seed coat to crack, start Germination, sowing seeds for seedling;

[0030] (2) After the seedlings grow to 0.4-0.6m, select the saplings with thick trunks and many branches, and soak the roots of the saplings in the compound microbial inoculum (the mass ratio is 20:28:15:25:1...

Embodiment 2

[0033] The present embodiment provides a method for breeding forest trees, the method comprising the following steps:

[0034] (1) Select different trees that can grow stably in heavy metal-contaminated soil in Xinxiang (Pashmina flounder, ginkgo biloba, paper mulberry, poplar, camphor, spruce, white elm, white bark pine, magnolia, cypress, locust, orientalis, juniper , Chinese locust and mulberry), to obtain seeds of different trees, the seeds were treated with 18% H before sowing 2 O 2 After disinfection treatment, soak in water for 5 hours, soak for 24 hours in an aqueous solution containing seed soaking agent (200mg / L gibberellin, 10mg / LBT rooting powder and 14mg / L 6-benzylaminopurine), wait for the seed coat to crack, start Germination, sowing seeds for seedling;

[0035] (2) After the seedlings grow to 0.4-0.6m, select the saplings with thick trunks and many branches, and soak the roots of the saplings in the compound microbial inoculum (the mass ratio is 18:26:19:22:1...

Embodiment 3

[0038] The present embodiment provides a method for breeding forest trees, the method comprising the following steps:

[0039] (1) Select different trees that can grow stably in heavy metal-contaminated soil in Xinxiang (Pashmina flounder, ginkgo biloba, paper mulberry, poplar, camphor, spruce, white elm, white bark pine, magnolia, cypress, locust, orientalis, juniper , Chinese locust and mulberry), to obtain seeds of different trees, the seeds were treated with 18% H before sowing 2 O 2 After disinfection treatment, soak in water for 5 hours, soak for 24 hours in an aqueous solution containing seed soaking agent (200mg / L gibberellin, 24mg / LBT rooting powder and 36mg / L 6-benzylaminopurine), wait for the seed coat to crack, start Germination, sowing seeds for seedling;

[0040] (2) After the seedlings grow to 0.4-0.6m, select the saplings with thick trunks and many branches, and soak the roots of the saplings in the compound microbial inoculum (the mass ratio is 14:24:12:26:1...

Abstract

The invention discloses a forest tree precise breeding method and application thereof, and the method comprises the following steps: soaking seeds of different trees before sowing, and then sowing and raising seedlings of the seeds; after the seedlings grow to 0.4-0.6 m, selecting saplings with thick and strong trunks and multiple branches, soaking the roots of the saplings in a compound microbial agent for 20-40 minutes, and then transferring the saplings into heavy metal polluted soil for mixed planting. By means of the breeding method, the forest trees capable of repairing the heavy metal contaminated soil can be accurately screened out, growth of the forest trees is promoted, and the heavy metal contamination degree of the soil is improved.

Description

technical field [0001] The invention belongs to the technical field of forest tree breeding, and in particular relates to a precision tree breeding method and application thereof. Background technique [0002] Forest genetics and breeding generally refer to the following studies: forest genetics, the genetic variation laws and evolutionary mechanisms of different traits of forest trees at the group, individual, cellular and molecular levels, providing a theoretical basis for the conservation and management of forest resources and the genetic improvement of forest trees. Genetic improvement of forest trees, strategies and procedures of forest improvement, formulation of breeding programs, theories and methods of introduction, selective breeding, cross breeding (including yield, quality, resistance and adaptive breeding, etc.) Forestry biotechnology uses genetic engineering, cell engineering, fermentation engineering, and enzyme engineering to genetically improve forest trees ...
