preparation example Construction

[0027] In the present invention, the preparation method of the medicinal residue decomposed product of Zhibai Dihuang Pill preferably comprises the following steps:

[0028] A, Anemarrhena chinensis, Cortex Phellodendri, Rehmannia glutinosa, Chinese yam, dogwood, Cortex Moutan, Poria cocos and Alisma are mixed, decocted in water, and solid-liquid separation is obtained to obtain medicinal residues;

[0029] B. The medicinal residues obtained in the step A are connected to the Trichoderma viridans F7 bacterial strain, and the slag is fermented to obtain the decomposed medicinal residues of Zhibai Dihuang Pills.

[0030] In the present invention, Anemarrhena, Cortex Phellodendri, Rehmannia glutinosa, Chinese yam, Cornus, Cortex Moutan, Poria and Alisma are preferably pulverized before the mixing. The pulverizing method is not particularly limited, and a pulverizing method well known to those skilled in the art can be used. The crushed particle size is preferably 10 to 30 mesh, ...

Embodiment 1

[0068] The organic fertilizer was prepared according to the following weight raw materials: 240kg of pig manure, 100kg of decomposed medicinal residues after the raw medicine of Zhibai Dihuang Pill was extracted, 40kg of corn stalks, 40kg of oyster shell powder, 24kg of potassium fulvic acid, 16kg of molasses, EM bacteria compost starter 10kg, cellulase 0.2kg.

[0069] The specific preparation method includes the following steps:

[0070] 1) Decomposition of traditional Chinese medicine dregs: The drug dregs extracted from Zhibai Dihuang Pills were inoculated with Trichoderma viridans F7 for aerobic fermentation to decompose. Adjust the moisture of the medicinal residue to 60%~70%, and the concentration of the bacterial liquid is about 1×10 8 The spore suspension of Trichoderma aeruginosa F7 per spore / mL was inserted into the dregs according to the inoculation amount of 1%, fully mixed and stirred, and natural fermentation was carried out, and the fermentation time was 10 d. ...

Embodiment 2

[0076] The organic fertilizer was prepared according to the following raw materials by weight: 300kg of pig manure, 180kg of decomposed medicinal residues after the extraction of Zhibai Dihuang Pills crude drug, 120kg of corn stalk, 90kg of oyster shell powder, 30kg of potassium fulvic acid, 18kg of molasses, EM bacteria compost Starter 12Kg, cellulase 0.3Kg.

[0077] A preparation method of pig manure fermentation organic fertilizer, comprising the following steps:

[0078] 1) Decomposition of traditional Chinese medicine dregs: The drug dregs extracted from Zhibai Dihuang Pills were inoculated with Trichoderma viridans F7 for aerobic fermentation to decompose.

Abstract

The invention provides a pig manure and medicine slag fermentation organic fertilizer as well as a preparation method and application thereof, and belongs to the technical field of organic fertilizerpreparation. The organic fertilizer is prepared from the following raw materials in parts by weight through fermentation: 50 to 70 parts of pig manure, 25 to 40 parts of thoroughly decomposed anemarrhena pill medicine slag, 10 to 30 parts of corn stalk subjected to blasting pretreatment, 10 to 20 parts of oyster shell powder, 5 to 8 parts of potassium fulvic acid, 3 to 5 parts of molasses, 1.5 to3.5 parts of EM germ compost fermenting agents and 0.02 to 0.07 part of cellulase. The enzyme activity of the cellulase is one hundred thousand to two hundred thousand U / g, wherein the thoroughly decomposed anemarrhena pill medicine slag is obtained by fermenting and thoroughly decomposing medicine slag through trichoderma virens F7 strains; the preservation code of the trichoderma virens F7 strains is CGMCC 3.17613. The organic fertilizer is prepared from the raw materials through twice fermentation. The organic fertilizer has rich nutrition; the nutrition proportioning is reasonable; the organic fertilizer can be applied to crop planting.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and particularly relates to a fermented organic fertilizer of pig manure and medicinal residues, and a preparation method and application thereof. Background technique [0002] At present, the annual amount of chemical fertilizers in my country is huge. The use of chemical fertilizers can not only quickly and effectively supplement soil fertility and provide the growth elements needed by crops, but also the relatively low prices of chemical fertilizers reduce the cost of farmers growing crops. But at the same time, the use of chemical fertilizers also makes us pay a huge price. For example, the arable land is becoming more and more serious, desertification and salinization are becoming more and more serious, the quality of agricultural products is declining, and the food is unhealthy. [0003] Compared with chemical fertilizers, bio-organic fertilizer saves time and labor. ...
