Description

Technical Field

[0001] The present invention belongs to the technical field of the preparation of organic fermentation fertilizers, and particularly relates to a functional organic fertilizer prepared from Rosa roxburghii Tratt residue. Background Art

[0002] Rosa roxburghii Tratt is a wild fruit growing in the southwestern region of China. In recent years, it has gradually attracted attention due to its rich nutritional components and unique flavor, and has become an emerging product in the fruit market. The fruit of Rosa roxburghii Tratt is rich in vitamin C, amino acids, minerals and various beneficial plant compounds, and has high health care value. Therefore, the cultivation and processing of Rosa roxburghii Tratt have gradually emerged. In the processing of Rosa roxburghii Tratt, the main products are Rosa roxburghii Tratt juice, Rosa roxburghii Tratt dried fruits and Rosa roxburghii Tratt jam, etc. However, these processing processes will produce a large number of by-products, namely Rosa roxburghii Tratt residue. Rosa roxburghii Tratt residue refers to the solid residue left after the juice extraction or other processing of Rosa roxburghii Tratt fruits, and contains nutrients such as cellulose, pectin, plant protein and trace elements. Although Rosa roxburghii Tratt residue contains these nutrients, due to the low content, it is difficult to be directly utilized, so the utilization efficiency in actual production is low, and it is often discarded as industrial waste, resulting in waste of resources.

[0003] Traditional Chinese medicine residue comes from the production of traditional Chinese medicine raw materials, the processing and preparation of traditional Chinese medicine decoction pieces, and the production of light chemical products containing traditional Chinese medicine components, etc. Among them, the amount of residue brought by the production of traditional Chinese patent medicine is the largest. Traditional Chinese medicine is mainly composed of plant, animal and part of mineral medicinal materials, and the plant medicinal materials account for more than 87%. At present, the production and processing of traditional Chinese medicinal materials in China are still in the primary stage. The extraction means are relatively single, and the extraction efficiency is relatively low. The traditional Chinese medicine residue remaining after extraction generally contains a large amount of crude protein, crude fat, cellulose, hemicellulose, lignin, amino acids, polysaccharides, oils, vitamins, organic acids and some nutrients necessary for the human body. The main reason for the rich nutrients in traditional Chinese medicine residue is due to the limited choice of modern pharmaceutical processes. Most pharmaceutical factories only utilize a small part of the effective components, so the traditional Chinese medicine residue after extraction still retains a large amount of chemical components and has extremely high development value.

[0004] Therefore, it is of great significance to prepare a functional organic fertilizer by mixing and fermenting Rosa roxburghii Tratt residue and traditional Chinese medicine residue to realize the resource utilization of Rosa roxburghii Tratt residue and traditional Chinese medicine residue. Summary of the Invention

[0005] According to the deficiencies of the prior art, the present invention uses Rosa roxburghii Tratt residue, traditional Chinese medicine residue and rice husk powder as the fermentation base materials for preparing the functional organic fertilizer. Through a specific ratio of mixing, and then spraying the constructed mixed fermentation bacterial liquid on the fermentation base materials, the functional organic fertilizer is obtained through composting fermentation. When used for fertilizing crops, it can promote the growth of crops, and thus solve the technical problems proposed in the background art. Specifically, the technical solution of the present invention includes the following contents:

[0006] A functional organic fertilizer prepared from Rosa roxburghii Tratt residue, and the preparation method of the functional organic fertilizer comprises the following steps:

[0007] The Rosa roxburghii Tratt residue, traditional Chinese medicine residue and rice straw powder are mixed to form a fermentation base material, and the mixed fermentation bacterial liquid is sprayed onto the fermentation base material and then wetted with water to form a fermentation base material to be fermented;

[0008] The fermentation base material is sequentially subjected to composting fermentation and drying treatment to obtain the functional organic fertilizer.

[0009] Furthermore, the preparation method of the mixed fermentation bacterial liquid comprises the following steps:

[0010] Monascus purpureus and Trichoderma koningii are respectively inoculated into solid culture dishes and placed in an incubator at 30 °C for 24 h to obtain a Monascus purpureus spore culture dish and a Trichoderma koningii spore culture dish;

[0011] The Monascus purpureus spore culture dish and the Trichoderma koningii spore culture dish are rinsed with sterile water and the rinsing solutions are combined to obtain a mixed spore suspension;

[0012] The mixed spore suspension is inoculated into a liquid culture medium and cultured to obtain a mixed fermentation bacterial liquid.

[0013] Furthermore, the strain number of the Monascus purpureus is CICC 40712.

[0014] Furthermore, the strain number of the Trichoderma koningii is CICC 13025.

[0015] Furthermore, the preparation method of the solid culture dish comprises the following steps:

[0017] Furthermore, the dosage of the sterile water rinsing is controlled at 20 ml - 30 ml.

[0018] Furthermore, the inoculation amount of the mixed spore suspension inoculation is 0.005 - 0.01 of the total weight of the liquid culture medium.

[0019] Furthermore, the preparation method of the liquid culture medium comprises the following steps:

[0020] Whey powder, ammonium sulfate, potassium dihydrogen phosphate, brown sugar and purified water are mixed in a weight ratio of 15-20:0.8-1:1.5-2:5-7:980-1000, heated to 50°C - 55°C and stirred until completely dissolved, and then sterilized at 121°C for 20 min - 30 min to obtain a liquid medium.

[0021] Further, the weight ratio of the mixed fermentation bacterial liquid to the fermentation base material is 1:80 - 100.

[0022] Further, the water content of the base material to be fermented is 55% - 65%.

[0023] Further, the conditions for compost fermentation include a compost height of 1 m - 1.5 m, a fermentation time of 8 days - 10 days, a turning frequency of once every 2 days, and a ventilation rate of 0.4 L / min - 0.5 L / min.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] By designing the composition components, the present invention uses Eucommia ulmoides residue, Astragalus membranaceus residue and Coptis chinensis residue to form traditional Chinese medicine residues. Eucommia ulmoides residue contains crude protein, crude fat and trace elements such as calcium, phosphorus and potassium. Astragalus membranaceus residue contains astragalus polysaccharide, amino acids and trace elements such as zinc and iron. Coptis chinensis residue contains alkaloids, flavonoids and organic acids, etc., which can make up for the deficiency of nutrients in Rosa roxburghii Tratt residue and improve the fertilizer efficiency of the fermented fertilizer. The traditional Chinese medicine residues, Rosa roxburghii Tratt residue and rice straw powder are mixed in a specific ratio to form a fermentation base material, and then the mixed fermentation bacterial liquid composed of Monascus purpureus and Trichoderma koningii is sprayed on the fermentation base material. Through the synergistic decomposition and fermentation of Monascus purpureus and Trichoderma koningii, the prepared functional organic fertilizer can promote the growth of crops when used for fertilizing crop growth.
