Planting method for high-yield platycodon grandiflorum

Abstract

The invention discloses a planting method for high-yield platycodon grandiflorum. The planting method is characterized by comprising the following aspects: (1) seed treatment, namely detoxifying platycodon grandiflorum seeds in a potassium permanganate solution, mixing the platycodon grandiflorum seeds with plant powder, then, carrying out plasma treatment, and then, carrying out constant-temperature germination acceleration; (2) seedling raising, namely carrying out high-temperature and high-pressure cooking on soil in a seedling raising box by using a plant powder solution, mixing the soil with a mixed fertilizer, and spreading the mixture on the seedling raising box; (3) soil treatment, namely, respectively spraying an abamectin solution and the plant powder solution on the soil, covering the soil by using a thin film, exposing the soil under blazing sun, and applying 470-520kg of mixed fertilizer per mu; (4) transplantation, namely dividing a planting ridge into a plant powder layer, a mixed fertilizer layer and a loess layer to be paved, and carrying out field planting by using the plant powder solution; and (5) carrying out daily management, namely concentrating the plant powder solution to 1 / 3 of original volume to irrigate and spray the platycodon grandiflorum.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-yield planting method of bellflower. Background technique [0002] Platycodon grandiflora, also known as bag flower, bell flower and mitral flower, is a perennial herb. Platycodon grandiflorum likes cool climate, cold resistance, and sunshine. It should be cultivated in hilly areas below 1100m above sea level, and sandy soil is suitable; in North China and central China , East China, Guangdong, Sichuan and other provinces are distributed and planted. Platycodon grandiflorum flowers are mostly dark blue or dark purple white, which can be used for ornamental purposes. for food. Platycodon grandiflorum contains 18 kinds of saponins such as platycodon grandiflora saponin, polygala saponin and polygalacic acid, which have the effects of expectorant, antitussive, hypoglycemic, antibacterial and anti-inflammatory, and anti-gastric ulcer. and economic v...

Problems solved by technology

[0003] The present invention is aimed at the existing problems: in terms of planting methods, the live broadcast method has a low germination rate and slow growth, while the greenhouse seedling cultivation method, due to the influence of various factors such as soil fertility, temperature, and moisture, also has a low germination rate, and even can only grow. If it reaches 70%-80%, the growth of seedlings is not vigorous, and the resistance to diseases and insect pests is weak; the planting of platycodon is vulnerable to root rot, powdery mildew and other pests and diseases. and pest resistance
