Platycodon grandiflorum planting method

Abstract

The invention discloses a platycodon grandiflorum planting method. The method comprises the following steps: (1) carrying out seedling raising: selecting biennial platycodon grandiflorum rhizomes, and carrying out seedling raising culture at the temperature of 21 DEG C to 23 DEG C, wherein soil for seedling raising is prepared from the following ingredients in parts by weight: 500 parts of nutritional soil, 800 parts of decomposed cattle manure, 500 parts of peat soil, 30 parts of saccharose and 50 parts of naphthyl acetic acid; (2) carrying out transplanting; and (3) carrying out fertilizer application: when the plant height reaches 30cm to 35cm, spraying a foliar fertilizer, wherein the foliar fertilizer is prepared from the following ingredients: 20 parts of anhydrous ethanol, 50 parts of naphthyl acetic acid, 20 parts of saccharose, 50 parts of aloe vera and 500 parts of water; and carrying out topdressing in July to September, wherein the fertilizer used in the topdressing process is prepared from the following ingredients in parts by weight: 170 parts of urea, 300 parts of calcium superphosphate, 20 parts of zinc sulfate, 10 parts of boric acid and 20 parts of radix polygalae. According to the platycodon grandiflorum planting method, the differentiation and development of roots of platycodon grandiflorum can be promoted, the development of woody parts is promoted, and the yield and quality of the platycodon grandiflorum are improved.

Description

technical field [0001] The invention relates to a traditional Chinese medicine cultivation method. More specifically, the present invention relates to a method for planting bellflower. Background technique [0002] Campanulaceae, also known as bag flower, bell flower, mitral flower, Campanulaceae Campanulaceae plant, perennial herb, Campanulaceae has a unique chrysanthemum penetrating the heart, used as medicine to expel phlegm, expel evil and avoid dampness, mend internal leakage and sore throat. The study found that the total saponin content in Platycodon grandiflorum was positively correlated with the size of the chrysanthemum heart of Platycodon grandiflorum. But at present, platycodon grandiflorum adopts the planting method of live seeding more in production, and its seed germination rate is low, and the phenomenon of root rot easily occurs in the planting process of platycodon grandiflorum, causes platycodon grandiflorum output low, and economic benefit is poor. In a...

Problems solved by technology

But at present, bellflower adopts the planting method of direct seeding more in production, and its seed germination rate is low, and the phenomenon of root rot easily occurs in the planting process of bellflower, causes bellflower yield to be low, and economic benefit is poor

In addition, in the process of planting Platycodon grandiflorum, the phenomenon of abuse or excessive use of pesticides and fertilizers is common, resulting in excessive drug residues and heavy metals.
