[0030] Example 1:
[0031] A planting method of Platycodon grandiflorum includes the following steps:
[0032] (1) Pretreatment of seeds
[0033] First spread the seeds to a thickness of 5 cm, and sun them for 1 d in sunny weather at 24°C, and turn them every 2 hours. After pretreatment, the seeds are soaked in a 0.3% potassium permanganate solution for 20 hours, then removed, rinsed and dried;
[0034] (2) Seed dressing
[0035] Dilute the carbendazim with water and mix it with Platycodon grandiflorum seeds, then dry at room temperature, and then dress the seeds with a bacterial fertilizer, which is a nitrogen-fixing bacteria;
[0036] (3) Renovation
[0037] Choose to plow 30cm deep on a flat land and level it to make a border. The border width is 1.2m and the border height is 14 cm. Then apply 2,000 kg of farm manure, 20 kg of potassium sulfate, and 5 kg of diammonium phosphate before planting. , Three-element compound fertilizer 10 kg;
