Special fertilizer for Radix Platycodonis, and preparation method thereof

Abstract

The invention relates to the technical field of fertilizers, and especially relates to a special fertilizer for Radix Platycodonis, and a preparation method thereof. The fertilizer comprises animal manure, corn grits, bagasse, malt, Rabdosia rubescens, radish leaves, Arctium lappa and high fat powder. The method comprises the following steps: mixing malt, Rabdosia rubescens and Arctium lappa, juicing the obtained mixture, adding water, boiling the obtained solution, cooling the boiled solution, inoculating with microzyme, carrying out constant temperature fermentation, inoculating with Bacillus amyloliquefaciens, carrying out constant temperature fermentation, continuously inoculating Bacillus subtilis, and carrying out temperature shift fermentation to obtain a fermentation liquid for later use; crushing the corn grit, bagasse and the radish leaves, uniformly stirring the crushed materials and the animal manure, placing the obtained uniform mixture in a sealed plastic barrel, and allowing the obtained mixture to stand for 12-18 h in order to obtain a fermentation product; and uniformly mixing the fermentation liquid with the fermentation product, carrying out microwave treatment, and uniformly mixing the microwave treated mixture with the high fat powder in order to obtain the fertilizer. The special fertilizer for Radix Platycodonis has the advantages of balanced nutrition, meeting of nutrition demands of Radix Platycodonis, enhancement of the disease resistance of Radix Platycodonis, and improvement of the emergence rate of Radix Platycodonis.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for platycodon grandiflora and a preparation method thereof. Background technique [0002] Platycodon grandiflorum, also known as burden flower, bell flower, mitral flower, is a perennial herb with a stem height of 20-120 cm, usually glabrous, occasionally densely covered with short hairs, unbranched, with few upper branches. The leaves are all in whorls, some are in whorls to all are alternate, sessile or have a very short stalk, the leaves are ovate, ovate-elliptic to lanceolate, the leaves are ovate or ovate-lanceolate, the flowers are dark blue or dark blue Purple and white, it can be used as an ornamental flower; its root can be used as medicine, which has the functions of relieving cough and expectorant, clearing the lung, and draining pus. It is commonly used in traditional Chinese medicine. [0003] Bellflower has become a popular plant because o...

AI Technical Summary

Problems solved by technology

[0003] Bellflower has become a popular plant because of its high medicinal value and economic value, but there are many problems in the planting of bellflower, such as bellflower is a perennial plant, its seed germination rate is low, and the continuous cropping method of long-term planting in the same land , is very susceptible to pathogen infection, making bellflower susceptible to disease, which in turn affects yield; and if the land preparation or field management is reasonable, it cannot meet the nutrients required for growth, which can easily lead to pests and diseases, and then affect the yield of bellflower. The phenomenon of plant diseases and insect pests Seriously, scholars have also done a lot of research on this. The prevention and control of its diseases and insect pests is mainly spraying reagents such as carbendazim and trichlorfon, the pollution rate is relatively large, and it is also easy to affect human health. Therefore, it is necessary to propose a A fertilizer that can enhance the disease resistance of platycodon grandiflora and inhibit the growth of harmful bacteria
