Embodiment 1

[0023] As shown in Figure 1, it is a process flow of the method for preparing mineral organic fertilizer by using earthworm to replace part of chicken manure, and the specific steps are as follows:

[0024] (1) Mix palygorskite and earthworm evenly at a weight ratio of 0.6 to 1.2, add 0.2 to 0.6% of microbial probiotics, mix and pile up the mixture to obtain a fermentation step, and the fermentation temperature is 55 to 65°C , the fermentation time is 5 to 7 days, and when the temperature exceeds 65°C during the fermentation process, automatic mechanical turning is carried out;

[0025] (2) Extruding, granulating and packaging the fermented mixture in step (1) to obtain the finished mineral organic fertilizer. The produced mineral organic fertilizer particles are uniform and round, with smooth surface, high compressive strength, good fluidity, microbial survival rate > 90%, granulation rate of 85-95%, and particle diameter of 3.5-4mm.

Embodiment 2

[0027] The mineral organic fertilizer that obtains with embodiment 1 is example to detect the fertilizer efficiency of product of the present invention:

[0028] The influence of the present invention on the yield and active ingredients of Angelica sinensis was tested. The test set 5 different fertilization levels, 0, 200, 300, 400, 500kg / mu, 5 fertilization levels, random block design, plot area 5m×6m=30m 2 , repeated 3 times, and compared with the local conventional fertilization rate. The planting density of Angelica sinensis is 33cm×30cm (6734 plants / mu) according to row spacing×plant spacing. A black mulch film with a film width of 80cm is used, the ridge width is 60cm, and the ridge spacing is 40cm. Three rows are planted in each ridge, the row spacing is 33m, and the plant spacing is 30cm. Double seedlings are planted, and each plot has 6 ridges.

[0029] The effects of mineral ecological organic fertilizer on the yield of Angelica sinensis are as follows:

[0030] ...

Embodiment 3

[0032] The indicator crop is peaches, and the amount of fertilizer applied is as follows: the control group - 800 kg of American diammonium (46% diammonium phosphate) per mu; the test group - 800 kg of mineral organic fertilizer per mu. test results:

[0033] The total yield per mu is 30,000 jin, of which the test group: 16,000 jin; the control group: 14,000 jin.

[0034] The peaches have been tested, and the quality control of various ingredients is as follows:

Abstract

The invention discloses a method for preparing mineral ecological organic fertilizer from lumbricus. According to the method, modified palygorskite, lumbricus and a microbial beneficial bacterium agent are subjected to mixed fermentation to prepare the mineral ecological organic fertilizer. The mineral ecological organic fertilizer is characterized by being prepared from, by weight, 40-60% of palygorskite powder, 40-60% of lumbricus and a small quantity of microbial beneficial bacteria. The method has the advantages that the problem of lumbricus residues in a pharmaceutical factory is solved, the quality of the obtained mineral organic fertilizer is improved, the usage amount of chemical fertilizer and pesticide can be reduced, and production cost can be reduced; besides, the constitutive property of soil can be obviously improved, the volume weight of soil can be reduced, the number of pores can be increased, and the breathability and water permeability of soil can become good; a good controlled release effect is achieved, microelements needed by crops are supplemented, crops are regulated to grow uniformly, and thus the quality of crops is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a method for preparing mineral ecological organic fertilizers by using earthworms. Background technique [0002] The use of chemical fertilizers and pesticides in China accounts for 35% of the world's total. About 150 million mu of cultivated land in the country is polluted, and the soil presents salinization, desertification, and heavy metal pollution. The market urgently needs a chemical fertilizer substitute that does not damage the environment and soil, but also can increase production and improve quality. There are many patents reporting on the production method of organic fertilizer, such as: organic-inorganic mixed fertilizer and its preparation method (96120245.9), the production method of bioactive organic fertilizer (02133027.1), the method of converting crop straw into liquid fuel and organic fertilizer (01127346.1), the production method ...
