Problems solved by technology

[0003] Sowing seedlings is an important way to introduce and reproduce rhododendrons. Not only can a large number of seedlings be obtained, but also new variant types suitable for growth in new environments can be obtained to a certain extent, which has a high value in the introduction and domestication of rhododendrons. The seedlings grown by sowing seedlings grow extremely slowly, which affects the application and promotion of Rhododendron in gardens

Embodiment 1

[0026] (1) Sterilize the seedling-raising substrate at 121° C. for 2 hours in a high-pressure steam sterilizer, select the current-year seeds of the sheep’s hemp to sow and raise the seedlings, and obtain the annual seedlings through cultivation;

[0027] (2) Isolate Rhododendron mycorrhizae from Rhododendron tomentosa root system, use MEA liquid culture medium 25 ℃ to propagate and cultivate the mycorrhizal fungi therein to obtain ERM liquid bacterial agent after 15-20 days;

[0028] (3) The inoculation time is selected in early March, and a small hole is dug near the root of the seedlings of the roe deer, and 15ml of the ERM fungus liquid is injected into the small hole with a pipette gun and covered with the matrix;

[0029] (4) Inoculate once every 6 days, the method is the same as step (3), and inoculate twice continuously.

Embodiment 2

[0031] (1) Sterilize the seedling-raising substrate at 121° C. for 2 hours in a high-pressure steam sterilizer, select the current-year seeds of the sheep’s hemp to sow and raise the seedlings, and obtain the annual seedlings through cultivation;

[0032] (2) Isolate Rhododendron mycorrhizae from Rhododendron tomentosa root system, use MEA liquid culture medium 25 ℃ to propagate and cultivate the mycorrhizal fungi therein to obtain ERM liquid bacterial agent after 15-20 days;

[0033] (3) The inoculation time is selected at the beginning of April; dig a small hole near the roots of the seedlings of the roe deer, inject 10 ml of the ERM fungal liquid into the small hole with a pipette gun and cover the substrate;

[0034] (4) Inoculate once every 5 days, the method is the same as step (3), and inoculate 3 times continuously.

Embodiment 3

[0036] (1) Sterilize the seedling-raising substrate with a high-pressure steam sterilizer at 121° C. for 2.5 hours, select the current-year-old seeds of the sheep’s hemp to sow and raise the seedlings, and obtain the annual seedlings through cultivation;

[0037] (2) Isolate Rhododendron mycorrhizae from Rhododendron tomentosa root system, use MEA liquid culture medium 25 ℃ to propagate and cultivate the mycorrhizal fungi therein to obtain ERM liquid bacterial agent after 15-20 days;

[0038] (3) The inoculation time is selected in mid-April; a small hole is dug near the root of the seedling of the roe deer, and the ERM fungus liquid of 12ml is injected into the small hole with a pipette gun and covered with the substrate;

[0039] (4) Inoculate once every 8 days, the method is the same as step (3), and inoculate 3 times continuously.

[0040] Inject the same volume of aseptic MEA liquid medium as a blank control for the annual sowing seedlings of the sheep roe deer; three mon...

Abstract

The invention discloses a mycorrhization technology of azalea sowing seedlings. The mycorrhization technology of the azalea sowing seedlings comprises the following steps: selecting rhododendron molle underyearling seeds to cultivate annual sowing seedlings; cultivating mycorrhizal fungi by using an MEA liquid culture medium to obtain ERM liquid fungi; digging small holes near the roots of rhododendron molle sowing seedlings, and injecting the ERM liquid fungi into the small holes by a pipette and covering with a seedling substrate; inoculating for once every other several days, continuously inoculating for several times, and observing the infection rate after three months. The mycorrhization technology of the azalea sowing seedlings has the main advantages that the infection effect is good, the mycorrhization of the azalea is realized, the growth of the azalea is promoted, and introduction and domestication of the azalea are promoted.

Description

technical field [0001] The invention relates to a nursery stock cultivation technology, in particular to a mycorrhizalization technology of rhododendron seedlings. Background technique [0002] Rhododendron mycorrhizae, also known as heather-like mycorrhizae (ERM for short), refers to the formation of some mycorrhizal fungi in the roots of Rhododendronaceae plants except Arbutus and Arctostaphylos. symbiotic complex structure. Some scholars believe that the reason why rhododendrons can survive under harsh environmental conditions depends largely on ERM fungi to relieve environmental stress, and reduce the damage of environmental stress to host plants through ERM fungi to improve the host plant Adaptability to this environment. [0003] Sowing seedlings is an important way to introduce and reproduce rhododendrons. Not only can a large number of seedlings be obtained, but also new variant types suitable for growth in new environments can be obtained to a certain extent, whic...
