Problems solved by technology

In the Chinese invention patent with publication number CN110073909A, the method of spraying DA-6 on the leaves at the flower bud stage (pregnant bud flowering stage) and topping the buds is more effective in promoting the increase of its yield, and has significant benefits to a certain extent. effect, but this method has problems such as the vegetative growth period is not controlled, the flowering period is earlier, the flower volume is large, and the flowering period is inconsistent, which brings troubles to centralized processing.

Embodiment 1

[0025] A cultivation and management method for increasing the yield of medicinal bellflower, said method comprising the steps of:

[0026] (1) Soil selection and building a shelter: Choose a sandy loam site with sufficient sunlight, deep soil, good drainage, and rich in organic matter to build a shelter;

[0027] (2) Deep plowing and opening: Before planting, deep plow the soil layer 30-40cm, dry the soil for 1-2 days, then apply 2000-2200kg of basal fertilizer per mu, open the compartment with a width of 160cm, and a ditch width of 32cm;

[0028] (3) Sowing: for the treatment of platycodon grandiflorum seeds before sowing, soak for 14-20h with 0.2-0.3% potassium permanganate solution; 25°C, humidity 65-70%, dig holes and sow on the box surface;

[0029] (4) On the 30th day after sowing, add quick-acting fertilizer once, in the form of foliar spraying, the amount of fertilizer per mu is 60kg, and after the average temperature of the day is higher than 18°C, use black plastic ...

Abstract

The invention discloses a cultivation management method for improving the yield of medicinal platycodon grandiflorum. According to the cultivation management method, flowering of the platycodon grandiflorum is controlled in the early stage, the flowering period is delayed, nutrition is concentrated to roots, root development and growth are promoted, and the yield is improved; and because the flourishing period of vegetative growth is over, meanwhile, the environment is not suitable, the flowering amount is less, appropriate measures are taken to promote centralized flowering, and then appropriate flower removing measures are taken; and due to concentrated flowering stages, the flower removing time can be shortened, and thus, the time and labor cost are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of bellflower cultivation and management, and in particular relates to a cultivation management method for increasing the yield of medicinal bellflower. Background technique [0002] Campanulaceae, also known as soil ginseng, bell flower, is a plant of Campanulaceae, Campanulaceae, a perennial herb. Platycodon grandiflorum is a kind of medicine and food. It uses underground rhizomes for medicinal purposes. It is mainly used to treat symptoms such as cough with excessive phlegm, sore throat, hoarseness, cough and vomiting of pus and blood. Health foods such as bellflower vegetables, bellflower shreds, and preserved bellflower fruits processed with bellflowers are not only delicious, but also have medical and health care effects, and are deeply loved by people. Because bellflower has high edible, medicinal and economic value, so the artificial planting of bellflower is more and more favored by growers. [0...
