Problems solved by technology

[0002] There are many problems in the newly planted seedlings in the landscaping process, such as: the growth of seedlings is slow, the survival rate of transplanting is low, and they are susceptible to diseases
In order to ensure their survival and growth, chemical regulation is often used in the transplanting process of seedlings, but it is easy to cause soil and substrate pollution, which has a greater impact on the later ornamental quality of green leafy ornamental seedlings and the quality and safety of medicinal trees

Embodiment 1

[0021] Implementation case Using Pine massoniana as the material, the above-mentioned six kinds of ectomycorrhizal fungi were mixed in equal proportions to make bacterial agents, inoculated in the roots of Pine massoniana seedlings, and the growth status of the seedlings was measured 90 days after inoculation, and the mycorrhizal root system of the seedlings was observed with a stereo microscope Rate. The saplings were transplanted in 30cm×25cm pots 90 days after inoculation, and the growth of the seedlings was observed one year after transplanting.

[0022] 1. Material preparation

[0023] Seedling cultivation: Collect the seeds of the masson pine in the current year and store them at 4°C for more than two months. Weigh 10 grams of seeds, soak and sterilize with 3% sodium hypochlorite solution for 15 minutes, wash and soak in water for 24 hours, then sow in plastic pots, and water once every other day to keep the soil surface moist.

[0024] Mix the mixed matrix A and the l...

Abstract

The invention discloses a method for optimizing nursery-grown plant cultivation by using ectomycorrhizal fungi. The method comprises the main process including the following steps: production of an ectomycorrhizal fungi agent, cultivation of tree seedlings, inoculation with the ectomycorrhizal fungi, and nutrition management of the tree seedlings after inoculation. In actual use, a pre-experiment can be performed according to different tree species, and a best ectomycorrhizal fungi strain is selected. 6 kinds of ectomycorrhizal fungi are adopted as materials to inoculate root systems of the tree seedlings, and the growth amount and the transplanting survival rate of the tree seedlings are significantly improved.

Description

technical field [0001] The invention belongs to the field of cultivation, in particular to a method for optimizing nursery stock cultivation by using microorganisms symbiotic with seedling stock, in particular to a method for optimizing seedling stock cultivation by utilizing ectomycorrhizal fungi. Background technique [0002] There are many problems in the newly planted seedlings in the landscaping process, such as: the growth of seedlings is slow, the survival rate of transplanting is low, and they are susceptible to diseases. In order to ensure their survival and growth, chemical regulation is often used in the transplanting process of seedlings, but it is easy to cause soil and substrate pollution, which has a greater impact on the later ornamental quality of green leafy ornamental seedlings and the quality and safety of medicinal trees. Ectomycorrhizal fungi are a type of soil fungi that are mutually beneficial and symbiotic with trees. After the mycorrhizal symbionts ...
