Embodiment 1

[0031] A planting method of bellflower, comprising the steps of:

[0032] (1) Pretreatment of seeds

[0033] First spread the seeds to a thickness of 5 cm, dry them in the sun at 24°C for 1 day, and turn them over every 2 hours. After the seeds are pretreated, soak the seeds in 0.3% potassium permanganate solution for 20 hours, then take them out, rinse and dry them;

[0034] (2) Seed dressing

[0035] After diluting the carbendazim agent with water, mix it well with the platycodon grandiflora seeds, then place it in the air to dry at room temperature, and then use bacterial fertilizer to dress the seeds after seed dressing, and the bacterial fertilizer is nitrogen-fixing bacteria agent;

[0036] (3) Whole crop

[0037] Choose to plow 30 cm deep on a flat plot, and level it to make a furrow. The width of the furrow is 1.2 m, and the height of the furrow is 14 cm. Then, 2 000 kg of farmyard manure, 20 kg of potassium sulfate, and 5 kg of diammonium phosphate are applied befor...

Embodiment 2

[0051] A planting method of bellflower, comprising the steps of:

[0052] (1) Pretreatment of seeds

[0053] First spread the seeds to a thickness of 7.5 cm, dry them in the sun at 25°C for 2 days, and turn them over every 3 hours. After the seeds are pretreated, soak the seeds in 0.4% potassium permanganate solution for 24 hours, then take them out, rinse and dry them;

[0054] (2) Seed dressing

[0055] After diluting the carbendazim agent with water, mix it well with the platycodon grandiflora seeds, then place it in the air to dry at room temperature, and then use bacterial fertilizer to dress the seeds after seed dressing, and the bacterial fertilizer is nitrogen-fixing bacteria agent;

[0056] (3) Whole crop

[0057] Choose to plow 35 cm deep on a flat plot, and level it to make a furrow. The width of the furrow is 1.35 m, and the height of the furrow is 15 cm. Then, 2 500 kg of farmyard manure, 25 kg of potassium sulfate, and 10 kg of diammonium phosphate are applied ...

Embodiment 3

[0071] A planting method of bellflower, comprising the steps of:

[0072] (1) Pretreatment of seeds

[0073] First spread the seeds to a thickness of 10 cm, dry them in the sun at 26°C for 3 days, and turn them over every 4 hours. After the seeds are pretreated, soak the seeds in 0.5% potassium permanganate solution for 28 hours, then take them out, rinse and dry them;

[0074] (2) Seed dressing

[0075]After diluting the carbendazim agent with water, mix it well with the platycodon grandiflora seeds, then place it in the air to dry at room temperature, and then use bacterial fertilizer to dress the seeds after seed dressing, and the bacterial fertilizer is nitrogen-fixing bacteria agent;

[0076] (3) Whole crop

[0077] Choose to plow 40 cm deep on a flat plot, and level it to make a furrow. The width of the furrow is 1.5 m, and the height of the furrow is 16 cm. Then, 3 000 kg of farmyard manure, 30 kg of potassium sulfate, and 15 kg of diammonium phosphate are applied bef...

Abstract

The invention discloses a platycodon grandiflorum planting method. The platycodon grandiflorum planting method is characterized in that seeds are soaked with a potassium permanganate solution after being pre-treated, then fished out, rinsed and aired, so that the seed germination rate can be improved; as the seeds are dressed with a bacterial fertilizer after seed dressing in a step (2), beneficial microorganisms in soil can be increased, elements, which cannot be directly utilized by plants, in soil and air are changed into nutrients that can be absorbed by the plants, and accordingly, the growth and the development of platycodon grandiflorum are promoted; as covering of a mulching film is performed after earthing, the moisture content and the humidity of soil can be guaranteed, and accordingly, the growth is promoted; a 35-45% ethephon 1000 times dilution is sprayed after top dressing, so that the flower and fruit thinning effects are remarkable, and the purpose of yield increase can be achieved. Platycodon grandiflorum planted by the method has the advantages of high yield and quality, the market potential is huge and the prospect is wide.
