[0027] A method for transplanting Tilia amurensis tissue culture seedlings includes the following steps:
[0028] (1) Seedling reforming. Before seedling reforming, disinfect and sterilize the involved instruments, roots of tissue culture seedlings and seedling culture medium. The disinfection should be as comprehensive as possible, including the tools and containers used. The roots of tissue culture seedlings should be rinsed with running water before use. After wiping with 75% alcohol, rinse with water again. The working environment adopts 84 disinfection;
[0029] Select well-growing tissue culture seedlings and transfer them to the seedling cultivation medium (500g MS liquid medium, add 1.0mg / l BA1g, activated carbon 0.5g, multivitamin 2g and penicillin 0.5g), and place in a ventilated room temperature environment with an air humidity of 65% , The cultivation time is 3d, and the after cultivation is obtained;
[0030] (2) Cultivation, screening and refining th...

[0035] (1) Seedling tempering, disinfection before tempering is the same as in Example 1;
[0036] Select well-growing tissue culture seedlings, transfer them to the seedling cultivation medium (500g MS liquid medium, add 1.0mg / l BA1.5g, activated carbon 0.5g, multivitamin 4g and penicillin 0.75g), and place them in a ventilated room temperature environment with air humidity 80%, the time of refining seedlings is 4d, the seedlings after refining are obtained
[0037] (2) Cultivation, screening and refining the seedlings and transplanting them into the mixed matrix for 3 months, supplementing with MS nutrient solution containing IBA 0.4 mg / l and GA 0.4 mg / l every week until the mixed matrix is poured, and the environmental humidity is 75% ;
[0038] (3) Transplanting. Before transplanting, loosen the soil, water, apply nitrogen, phosphorus and potassium compound fertilizer, trace elements and microbial inoculants, and spray herbicides and insecticides regularly.

[0042] (1) Seedling tempering, disinfection before tempering is the same as in Example 1;
[0043] Select well-growing tissue culture seedlings, transfer them to the seedling cultivation medium (500g MS liquid medium, add 1.0mg / l BA2g, activated carbon 0.5g, multivitamin 5g and penicillin 1g), and place them in a ventilated room temperature environment with an air humidity of 90%. Refining the seedlings takes 5 days to obtain the seedlings after refining;
[0044] (2) Cultivation, screening and refining the seedlings and transplanting them into the mixed matrix for 2 months, supplementing with MS nutrient solution containing IBA0.5mg / l and GA0.5mg / l every week until the mixed matrix is poured, and the environmental humidity is 80% ;
[0045] (3) Transplanting. Before transplanting, loosen the soil, water, apply nitrogen, phosphorus and potassium compound fertilizer, trace elements and microbial inoculants, and spray herbicides and insecticides regularly.
