Embodiment 1

[0027] A method for transplanting tilia tissue culture seedlings, comprising the steps of:

[0028] (1) For seedling hardening, before hardening, sterilize the equipment involved, the roots of tissue culture seedlings and the medium for hardening seedlings. The disinfection should be as comprehensive as possible, including the tools and containers used. After wiping with 75% alcohol, rinse with water again. The working environment adopts 84 disinfection;

[0029] Screen the well-growing tissue cultured seedlings, move them into the hardening medium (500g of MS liquid medium, add 1.0mg / l BA1g, 0.5g of activated carbon, 2g of multivitamins and 0.5g of penicillin), and place them in a ventilated room temperature environment with an air humidity of 65% , the hardening time is 3 days, and the hardened seedlings are obtained;

[0030] (2) Cultivate, screen and transplant the seedlings into the mixed substrate for 2 months, supplement the MS nutrient solution containing IBA0.3mg / l ...

Embodiment 2

[0035] (1) seedling hardening, disinfection before hardening is with embodiment 1;

[0036] Screen the well-growing tissue cultured seedlings, move them into the seedling hardening medium (500g of MS liquid medium, add 1.0mg / l BA1.5g, activated carbon 0.5g, multivitamin 4g and penicillin 0.75g), place in a ventilated room temperature environment, the air humidity 80%, the hardening time is 4 days, and the hardened seedlings are obtained;

[0037] (2) Cultivate, screen and transplant seedlings into mixed substrate for 3 months, replenish MS nutrient solution containing IBA0.4mg / l and GA0.4mg / l every week until the mixed substrate is poured thoroughly, and the ambient humidity is 75% ;

[0038] (3) Transplanting. Before transplanting, loosen the soil of the plot to be transplanted, water it, apply nitrogen, phosphorus and potassium compound fertilizers, trace elements and microbial agents, and regularly spray herbicides and insecticides.

[0039] Step (2) The mixed matrix comp...

Embodiment 3

[0042] (1) seedling hardening, disinfection before hardening is with embodiment 1;

[0043] Screen the well-growing tissue cultured seedlings, move into seedling hardening medium (500g of MS liquid medium adds 1.0mg / l BA2g, gac 0.5g, multivitamin 5g and penicillin 1g), place in ventilated room temperature environment, air humidity 90%, The hardening time is 5 days, and the hardened seedlings are obtained;

[0044] (2) Cultivate, screen and transplant the seedlings into the mixed substrate for 2 months, replenish the MS nutrient solution containing IBA0.5mg / l and GA0.5mg / l every week until the mixed substrate is poured thoroughly, and the ambient humidity is 80% ;

[0045] (3) Transplanting. Before transplanting, loosen the soil of the plot to be transplanted, water it, apply nitrogen, phosphorus and potassium compound fertilizers, trace elements and microbial agents, and regularly spray herbicides and insecticides.

[0046] Step (2) The mixed matrix components include MS nut...

Abstract

The invention discloses a transplanting method of tilia amurensis tissue culture seedlings, and relates to the technical field of plant tissue culture. The method comprises the following steps: hardening seedlings, screening tissue culture seedlings, transferring the tissue culture seedlings into a seedling hardening culture medium, and placing the seedling hardening culture medium in a ventilatedroom-temperature environment with the air humidity of 65-90% for 3-5 days to obtain the hardened seedlings; culturing, screening the hardened seedlings, transplanting the hardened seedlings into a mixed matrix for 2-3 months, and supplementing an MS nutrient solution containing 0.3-0.5 mg / l of IBA and 0.2-0.5 mg / l of GA every week until the mixed matrix is thoroughly watered and environment humidity reaches 70-80%; and transplanting. The screened tissue culture seedlings have good environmental adaptability, the survival rate and quality of the transplanted tissue culture seedlings are improved, the method is remarkable in effect, and the average transplanting survival rate reaches 97%.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, and more specifically relates to a method for transplanting Tilia Tilia tissue culture seedlings. Background technique [0002] Tilia is an arbor, and as the main nectar source plant in China, it has important economic value. [0003] Generally, the cultivation of tissue culture seedlings includes hardening, the purpose of which is to improve the adaptability of tissue culture seedlings to external environmental conditions, improve their photosynthetic ability, promote the robustness of tissue culture seedlings, and finally achieve the purpose of improving the survival rate of tissue culture seedlings transplanted. Domestication should be carried out from environmental factors such as temperature, humidity, light, and presence of bacteria. Within a few days of domestication, the environmental conditions should be similar to those at the time of cultivation; in the later stages of dom...
