Embodiment 1
[0020] Present embodiment provides a kind of pine seed seedling raising method, following steps:
[0021] 1. Seed pretreatment
[0022] 1) Variable temperature soaking treatment: Soak the seeds in 50°C water for 0.5h; then adjust the water temperature to 40°C, soak for 10h, and continuously inject air or oxygen into the water so that the dissolved oxygen in the water reaches 23mg / L; Add 40% traditional Chinese medicine growth-promoting solution to the water, lower the temperature to 25°C and continue soaking for 2 hours, and adjust the dissolved oxygen in the water to 18mg / L; pick it up, disinfect with 0.1% potassium permanganate solution, and then let it dry naturally Dry;
[0023] 2) Variable temperature germination: pick up the seeds treated in step 1) and put them in the germination room. The temperature is controlled at 25°C for 3 hours, then the temperature is raised to 30°C for 3 hours, and then the temperature is raised to 35°C for 1 hour. Finally, the temperature wa...
Embodiment 2
[0030] Present embodiment provides a kind of pine seed seedling raising method, following steps:
[0031] 1. Seed pretreatment
[0032] 1) Variable temperature soaking treatment: Soak the seeds in water at 40°C for 1 hour; then adjust the water temperature to 30°C, soak for 12 hours, and continuously inject air or oxygen into the water so that the dissolved oxygen in the water reaches 20 mg / L; then soak in water Add 20% traditional Chinese medicine growth-promoting solution, lower the temperature to 22°C and continue soaking for 5 hours, and adjust the dissolved oxygen in the water to 15mg / L; pick it up, sterilize with 0.05% potassium permanganate solution, and then dry it naturally ;
[0033]2) Variable temperature germination: pick up the seeds treated in step 1) and put them in the germination room. The temperature is controlled at 20°C for 5 hours, then the temperature is raised to 25°C for 5 hours, and then the temperature is raised to 30°C for 2 hours. Finally, the tem...
Embodiment 3
[0041] Present embodiment provides a kind of pine seed seedling raising method, following steps:
[0042] 1. Seed pretreatment
[0043] 1) Variable temperature soaking treatment: Soak the seeds in water at 45°C for 0.8h; then adjust the water temperature to 35°C, soak for 11h, and continuously inject air or oxygen into the water so that the dissolved oxygen in the water reaches 21mg / L; Add 30% traditional Chinese medicine growth-promoting solution to the water, lower the temperature to 23°C and continue soaking for 3 hours, and adjust the dissolved oxygen in the water to 16mg / L; pick it up, disinfect with 0.05% potassium permanganate solution, and then let it dry naturally Dry;
[0044] 2) Variable temperature germination: pick up the seeds treated in step 1) and put them in the germination room. The temperature is controlled at 22°C for 4 hours, then the temperature is raised to 27°C for 4 hours, and then the temperature is raised to 32°C for 1.5 hours. , and finally raise ...
