Problems solved by technology

However, the three major bases are all facing a problem: the root rot, fusarium wilt, and root-knot nematode caused by repeated cropping of bellflowers seriously affect the yield and quality of bellflowers in the three bases
The drug farmers of the three bases went to other places to plant medicinal materials, resulting in a sharp drop in the output of the three platycodon planting bases
However, the utilization rate of fertilizers is low when applied by spreading; it is easy to damage the roots of platycodon grandiflorum and take a lot of work.

Embodiment 1

[0033] Platycodon grandiflora biological compound bacterial fertilizer is prepared according to weight percentage: 9% bacterial agent, 57% macromolecular natural organic matter, 12% large granular urea, 12% slow-release coated urea, and 10% phosphorus-potassium compound fertilizer. Among them, the macromolecular natural organic matter is mixed with soybean meal and peanut shell according to the weight of 1:1. Mix well and pack into bags.

Embodiment 2

[0038] Platycodon grandiflorum biological compound bacterial fertilizer is prepared according to weight percentage ratio:

[0039] Bacteria agents accounted for 10%, macromolecular natural organic matter 55%, large granular urea 12%, slow-release coated urea 12%, and phosphorus-potassium compound fertilizer 11%. Among them, the macromolecular natural organic matter is mixed with soybean meal and corncob according to the weight ratio of 1:1. Mix well and pack into bags.

[0041]

[0042] The data in Table 2 support that Platycodon grandiflorum biological compound bacterial fertilizer can significantly inhibit root-knot nematode and root rot caused by repeated cropping; and increase its yield.

Embodiment 3

[0044] Platycodon grandiflorum biological compound bacterial fertilizer is prepared according to weight percentage ratio:

[0045] Bacteria agents accounted for 5%, macromolecular natural organic matter 60%, large granular urea 11%, slow-release coated urea 11%, and phosphorus and potassium compound fertilizer 13%. Among them, the macromolecular natural organic matter is mixed with soybean meal and straw according to the weight ratio of 1:1. Mix well and pack into bags.

[0046] Table 3 Effects of bellflower biological compound bacterial fertilizer on disease, quality and yield

[0047]

[0048] The data in Table 3 shows that Platycodon grandiflorum biological compound bacterial fertilizer can not only reduce the incidence of root-knot nematode and root rot, increase yield, but also increase soluble sugar and protein, and increase taste.

Abstract

The invention relates to a biological composite bacterium fertilizer and belongs to the field of bio-fertilizer. A special biological composite bacterium fertilizer for platycodon grandiflorum is composed of the following components in percentage by weight: 5-10% of bactericide, 55-60% of macromolecule natural organic matter, 10-13% of large granular urea, 10-12% of controlled-release sulfur coated urea, and 5-15% of nitrogen-phosphorus-potassium compound fertilizer. The biological composite bacterium fertilizer provided by the invention has the advantages that the quantity and activity of the beneficial microorganism are improved, the harmful microorganism is inhibited, the physical and chemical properties of soil are improved, the nutrients of soil are increased and balanced, and the residues of farm chemicals and fertilizer and other harmful matters in the soil are degraded. After the biological composite bacterium fertilizer is applied, platycodon grandiflorum can be repeatedly planted in non continuous cropping or continuous cropping land, and the quality and the yield of platycodon grandiflorum are improved.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a special biological compound bacterial fertilizer for Platycodon grandiflorum. Background technique [0002] Bellflower ( Platycodon grandiflorum A.DC.) is the dried root of the perennial herb of Campanulaceae. It is one of the 40 most sold traditional Chinese medicinal materials in my country. It is flat in nature, bitter in taste, and pungent. Efficacy of evacuating pus and eliminating carbuncle. Modern studies have shown that platycodon grandiflorum also has a wide range of pharmacological activities such as lowering blood pressure, dilating blood vessels, lowering blood sugar, anti-cholinergic, anti-allergic, anti-tumor and improving immunity, so it is widely used in various prescriptions and clinics. While Platycodon grandiflorum is used as medicine in China, Japan and Korea, it is also eaten in large quantities in China, North Korea and South Korea, and it is also us...
