[0021] Example 1
[0022] A method for dwarfing potted ginkgo includes the following steps:
[0023] (1) Choose a mother tree with a tree age of about 80 years to collect seeds, pick the large-grained seeds to peel and dry in the shade, store them in wet sand, and treat them to break dormancy;
[0024] (2) Choose a suitable seedling substrate, the substrate formula is: vegetable garden soil, river sand and compound fertilizer are mixed in a ratio of 50:50:1, and a broad-spectrum fungicide is used to disinfect the seedling substrate while adding superphosphoric acid The pH value of calcium regulating substrate is 5-6;
[0025] (3) Soak the seeds with 10% trisodium phosphate solution for 20 minutes before sowing, lay the ginkgo nucleus flat when sowing, and cover with straw after sowing;
[0026] (4) Watering once every 7 days after sowing until the emergence of seedlings, watering once a day after emergence, and applying 1500 ml of 0.3% potassium dihydrogen phosphate per square meter of...
