Problems solved by technology

As vermicompost is another high-quality by-product after earthworm digestion, how to produce higher-quality vermicompost when cultivating earthworms is rarely reflected in existing technologies and invention patents
Existing technologies only focus on the use of earthworms to digest and treat organic solid waste, and how to use organic solid waste to breed better earthworms, ignoring the impact of using different organic solid wastes and different earthworm inoculation densities on the content of vermicompost. High in organic matter, nitrogen, phosphorus, potassium, and humic acids

Embodiment 1

[0025] A preparation method of special organic fertilizer for flue-cured tobacco with vermicompost as substrate, comprising the following steps:

[0026] (1) Preparation of mixed base material: Select and level the land and harden the ground, build a mixing tank and install a tank-type turning machine, and mix domestic sludge, cow dung and straw according to the mass ratio of 5:4:1 In the trough, the straw is placed in the bottom layer, the cow dung is placed in the middle layer, and the sludge is placed in the upper layer. A layer of concave-convex rod stone powder is laid between the straw and cow dung and between the cow dung and the sludge, and the turner is turned on. Stir the materials to obtain a mixed base material for later use; wherein, the attapulgite powder used is specially treated attapulgite powder, and the specially treated attapulgite powder is obtained by the following method: take attapulgite powder and add dilute hydrochloric acid (0.2mol / L ), after mixing ...

Embodiment 2

[0034] (1) Preparation of mixed base material: Select and level the land and harden the ground, build a mixing tank and install a tank-type turning machine, and mix domestic sludge, cow dung and straw according to the mass ratio of 5:4:1 In the trough, the straw is placed in the bottom layer, the cow dung is placed in the middle layer, and the sludge is placed in the upper layer. A layer of concave-convex rod stone powder is laid between the straw and cow dung and between the cow dung and the sludge, and the turner is turned on. The materials are stirred to obtain the mixed base material, which is set aside;

[0035] The power of the trough turning and throwing machine installed in the mixing tank is not less than 12kw, and the overall thickness of domestic sludge, cow dung and straw in the mixing tank is controlled at 80cm; the comprehensive moisture content of the final mixed base material is controlled to 55%;

[0036] (2) Fermentation of mixed base material: Mix the starte...

Embodiment 3

[0042] (1) Preparation of mixed base material: Select and level the land and harden the ground, build a mixing tank and install a tank-type turning machine, and mix domestic sludge, cow dung and straw according to the mass ratio of 5:4:1 In the trough, the straw is placed in the bottom layer, the cow dung is placed in the middle layer, and the sludge is placed in the upper layer. A layer of concave-convex rod stone powder is laid between the straw and cow dung and between the cow dung and the sludge, and the turner is turned on. The materials are stirred to obtain the mixed base material, which is set aside;

[0043] The power of the trough turning and throwing machine installed in the mixing tank is not less than 12kw, and the overall thickness of domestic sludge, cow dung and straw in the mixing tank is controlled at 70cm; the comprehensive moisture content of the final mixed base material is controlled to 50%;

Abstract

The invention relates to a preparation method of special organic fertilizer for flue-cured tobacco with wormcast as a substrate. The preparation method comprises the following steps: (1) preparing a mixed base material; (2) fermenting the mixed base material; (3) adding EM bacteria; (4), laying a earthworm material bed; (5), preparing mixed raw materials; (6), mixing and producing the fertilizer: pelletizing the mixed raw materials, then adding a diluted EM bacteria solution, stirring evenly to get a granular base material, finally according to weight percentage, mixing 60% of the granular base material, 10% urea, 18% of ammonium dihydrogen phosphate, and 12% of potassium sulfate evenly, packaging, and obtaining the special organic fertilizer for the flue-cured tobacco. The organic fertilizer prepared by the invention not only improves the microbial living environment in soil, enhances the soil fertility and the air permeability, but also improves the utilization rate of inorganic fertilizer so as to achieve the goal of improving the yield and quality of tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a method for preparing a special organic fertilizer for flue-cured tobacco using vermicompost as a substrate. Background technique [0002] With the rapid development of large-scale and intensive planting in my country, especially the improper selection of bio-organic fertilizer raw materials, poor quality, unreasonable formula, shortage of cultivated land, abuse of chemical fertilizers, and the lack of scientific crop rotation and crop replacement mechanisms for flue-cured tobacco, resulting in Poor quality of tobacco products, severe degradation of soil fertility and weakening of soil biological activity are common problems in most flue-cured tobacco growing areas. [0003] In addition, the scale and intensification of cattle farms in my country is increasing, and the pollution of cow dung to the environment is becoming more and more prominent. Cow dung bi...
