Abstract

The invention belongs to the technical field of fertilizer and particularly relates to a cow-dung-fermented organic fertilizer with a slow release function. The organic fertilizer comprises, by weightpercentage, 45-70% of cow dung, 3-20% of bran powder, 0.1-5% of an EM stock solution, 5-35% of diatomite, 10-30% of active charcoal and 1-10% of starch. The organic fertilizer has the following advantages that (1) the adaptation range is wide, both dry cow dung and fresh cow dung can be used as raw materials, and the efficiency is extremely high; (2) the fermentation generally lasts for 3-6 days,the fermentation cycle is short, and large-scale production can be realized; (3) no screening is needed, and the yield is as high as 90% or above; (4) the organic fertilizer has high fertilizer efficiency and a good slow release effect, the dosage in practical application is small, and by adopting the method, the dosage can be greatly reduced to about two thirds of that of organic fertilizer soldon the market at present when the same fertilization effect is achieved.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, in particular to a method for fermenting organic fertilizer with cow dung with a slow-release function. Background technique

[0002] In recent years, with the continuous improvement of people's living standards, people's demand for food crops is also increasing. The increase of grain production is inseparable from fertilizers. At present, the organic fertilizers used in grain production are mainly quick-acting fertilizers, which are characterized by quick effects, but the disadvantage is that they have a short service life and need to be topdressed many times. Although organic fertilizers can provide sufficient nutrients for crops, crops have different requirements and absorption rates for nutrients in different growth cycles, which will lead to rapid loss of unabsorbed nutrients in different growth periods, making fertilizers The utilization rate of the nutrients in the food is greatly red...

Examples

Embodiment 1

[0039] A kind of cow dung fermented organic fertilizer with slow-release function provided by the present embodiment, by weight percentage, comprises the following components:

[0040]

[0041] The preparation method of this organic fertilizer is as follows:

[0042] (1) Prepare raw materials: Prepare raw materials according to the above formula ratio;

[0043] (2) Primary mixing: first mix starch, 20% activated carbon and 5% diatomaceous earth evenly, then evenly spray 1% EM stock solution in the mixture, and leave it for 0.5 hours to make the EM stock solution fully absorbed;

[0044] (3) Secondary mixing: uniformly mix the remaining materials with the primary mixing;

[0045] (4) Anaerobic fermentation: The above raw materials are compacted and piled up, and sealed anaerobic fermentation is carried out for 4 days, so that the fermentation temperature is kept between 45°C and 75°C. At this time, most of the harmful pathogenic microorganisms have been killed , and the co...
