Embodiment 1

[0025] Base fertilizer formula: 15 parts of plant ash, 6 parts of potassium sulfate, 6 parts of borax, 10 parts of diammonium phosphate, 10 parts of magnesium sulfate, and 20 parts of urea.

[0026] Cultivation method:

[0027] a. Open the box: choose humus soil or sandy loam soil with deep soil layer, loose and fertile, and good drainage to open the box. The box surface width is 1.2m, the ditch width is 0.3m, and the ditch depth is 0.4m;

[0028] b. Sowing: Apply base fertilizer with an application rate of 50kg / acre, then sow seeds by sowing on the van, then cover the soil with 3cm, and cover the shading net on the van. The width of the shading net is 1.6m. The rate is 75%. The shading net is covered by pressing the two ends of the car surface with soil, and inserting small wooden sticks and bamboo sticks into the edge of the net to fix the shading net on both sides of the car surface;

[0029] c. Management: When the bellflower seedlings grow to a height of 3cm unearthed, c...

Embodiment 2

[0035] Base fertilizer formula: 35 parts of plant ash, 10 parts of potassium sulfate, 10 parts of borax, 16 parts of diammonium phosphate, 16 parts of magnesium sulfate, 40 parts of urea.

[0036] Cultivation method:

[0037] a. Open the box: choose humus soil or sandy loam soil with deep soil layer, loose and fertile, and good drainage to open the box. The box surface width is 1.2m, the ditch width is 0.3m, and the ditch depth is 0.4m;

[0038] b. Sowing: Apply base fertilizer at an application rate of 60kg / acre, then sow seeds on the box surface, then cover the soil with 5cm, and cover the box surface with a shading net. The width of the shading net is 1.6m. The rate is 85%. The shading net is covered by pressing the two ends of the car surface with soil, and inserting small wooden sticks and bamboo sticks into the edge of the net to fix the shading net on both sides of the car surface;

[0039] c. Management: When the bellflower seedlings grow to a height of 3cm unearthed,...

Embodiment 3

[0045] Base fertilizer formula: 20 parts of plant ash, 7 parts of potassium sulfate, 7 parts of borax, 12 parts of diammonium phosphate, 12 parts of magnesium sulfate, and 25 parts of urea.

[0046] Cultivation method:

[0047] a. Open the box: choose humus soil or sandy loam soil with deep soil layer, loose and fertile, and good drainage to open the box. The box surface width is 1.2m, the ditch width is 0.3m, and the ditch depth is 0.4m;

[0048] b. Sowing: Apply base fertilizer with an application rate of 50kg / acre, then sow seeds by sowing on the van, then cover the soil with 3cm, and cover the shading net on the van.

Abstract

The invention discloses a cultivating method for increasing the survival rate of platycodon grandiflorum seedlings. The method comprises the steps of compartment opening, seeding, managing, net taking, weeding, topping and flower pinching off and harvesting. According to the method, base fertilizer is applied through compartment opening, seeding is then carried out, and firstly nutrition needed in the growing process of platycodon grandiflorum is guaranteed; secondly, shading screen covering is carried out immediately, by applying a shading screen, direct washing of rain drops on seeds, seedlings and soil can be avoided, the granular structure of the soil is maintained, soil caking is prevented, and the emergence rate and the survival rate of the seedlings are increased; by applying the shading screen, the temperature of the bed surface can also be lowered, intense-light irradiation is avoided, the soil is kept moist, and growth of the platycodon grandiflorum is facilitated; the reasonable use of the shading screen is combined with the weeding, topping and flower pinching off, and thus the problem that the survival rate of the seedlings is low, and consequently the yield of the platycodon grandiflorum is low is solved.
