Embodiment 1
[0026] S1. Soaking and softening: First, the aquatic canna seeds to be planted are cleaned twice by the cleaning equipment, and then in March in spring, soaked in potassium permanganate solution for 6 hours, and soaked for 20 hours at a temperature of 20 °C. After the seed coat fully absorbs water and becomes soft, pick it up with an iron mesh and drain the water on it with a dry cloth. The concentration of potassium permanganate solution is 1.5mol / L;
[0027] S2. Peeling and disinfection: File the softened seed coat with a file, then soak it in a chlorothalonil solution at 20-30°C for 15 hours, remove it and drain it. The concentration of the chlorothalonil solution is 0.5mol / L;
[0028] S3. Sowing and covering soil: Sow the seeds sterilized in step S2 in the prepared seedbed soil respectively. After the sowing is completed, cover the soil with a thin layer of sandy soil, put it in a warm and humid environment, and control the temperature at 15°C. Water once a day and germina...
Embodiment 2
[0032] S1. Soaking and softening: First, the aquatic canna seeds to be planted are washed 3 times by the cleaning equipment, and then soaked in potassium permanganate solution for 6.25 hours in 3.5 months of spring, and soaked for 22 hours at a temperature of 23 °C After the seed coat fully absorbs water and becomes soft, pick it up with an iron mesh and drain the water on it with a dry cloth. The concentration of potassium permanganate solution is 2mol / L;
[0033] S2. Peeling and disinfection: File the softened seed coat with a file, then soak it in a chlorothalonil solution at 23°C for 16 hours, remove and drain, and the concentration of the chlorothalonil solution is 1 mol / L;
[0034] S3. Sowing and covering soil: Sow the seeds sterilized in step S2 in the prepared seedbed soil respectively. After sowing, cover the soil with a thin layer of sandy soil, put it in a warm and humid environment, and control the temperature at 16°C. Water once a day and germinate after 2.3 weeks...
Embodiment 3
[0038] S1. Soaking and softening: First, the aquatic canna seeds to be planted are washed twice by the cleaning equipment, and then in April in spring, soaked in potassium permanganate solution for 5 hours, and soaked for 23 hours at a temperature of 25 °C. After the seed coat fully absorbs water and becomes soft, pick it up with an iron mesh and drain the water on it with a dry cloth. The concentration of potassium permanganate solution is 2.5mol / L;
[0039] S2. Peeling and disinfection: file the softened seed coat with a file, then soak it in the chlorothalonil solution at 25°C for 17 hours, remove it and drain it. The concentration of the chlorothalonil solution is 1.5mol / L;
[0040] S3. Sowing and covering with soil: Sow the seeds sterilized in step S2 in the prepared seedbed soil respectively. After sowing, cover the soil with a thin layer of sandy soil, place it in a warm and humid environment, and control the temperature at 17°C. Water once a day and germinate after 2.5...
