Problems solved by technology

There are also domestic precedents of using straw to make fertilizer, but the process is simple and the technology content is low. The product adopts the traditional composting method, using straw to make ordinary compost. The effect of fertilizer use is slow, the proportion of straw is small, and the product is not shaped, so it has not been promoted. use

Effect test

Embodiment 1

[0036] Cooked straw powder 20%

[0037] Putrescine 30%

[0038] Urea 15%

[0039] Superphosphate 15%

[0040] Monoammonium Phosphate 8%

[0041] Potassium sulfate 10%

[0042] Trace elements 2%

[0043] 2) Preparation process

[0044] ①Crush the straw and put it in the pond for rottening. The straw decay process: A. Heating stage: from normal temperature to 50°C, it usually only takes one day. B. High temperature stage: it usually only takes 2 days from 50°C to 70°C. C. Cooling stage: drop from high temperature to below 50°C, generally mature for about 10 days, decompose straw, dry, crush, and pass through a 50-70 mesh sieve to obtain mature straw powder;

[0045] ②Preparation of putrescine

[0046] The weathered coal, the raw material of ammonium putrescens, is ball milled and passed through a 100-150-mesh sieve; then mixed with ammonia water or ammonium bicarbonate and water with a concentration of 12%-17%, the ratio is 1: (0.2-0.5) / (0.4- 0.6), seal in the reaction ...

Embodiment 2

[0053] The formula and preparation method are the same as in Example 1, and the difference from Example 1 is that potassium sulfate is replaced with Potassium Chloride, and the effect of Example 1 can be reached equally.

Embodiment 3

[0055] The preparation method of this embodiment is the same as embodiment 1, and the difference of embodiment 1 is that the weight ratio raw material formula of its organic multi-element granular fertilizer is:

[0056] Cooked straw powder 20%

[0057] Putrescine 35%

[0058] Urea 10%

[0059]Superphosphate 15%

[0060] Monoammonium Phosphate 9%

[0061] Potassium sulfate 8%

[0062] Trace elements 3%

[0063] The effect of Embodiment 1 can also be achieved.

Abstract

A granular multi-element organic fertilizer is prepared from the straw and stalk through cutting off, adding humic acid, fermenting, chelating reacting, and adding trace elements. It is rich in N,P,K, trace elements, humic acid, etc.

Description

technical field [0001] The present invention belongs to the preparation method of a kind of granular fertilizer of biochemical technology. Specifically, the composted decomposed matter of crop straws, natural humus and trace elements are used as basic raw materials, and the non-toxic and non-toxic fertilizer is refined by modern technology and scientific formula. Harmful green agricultural fertilizers and methods for their manufacture. technical background [0002] In the process of agricultural production, straw has always been a waste. The common phenomenon is that after harvesting, the straw is piled up on the edge of the field, or burned in large quantities, causing environmental pollution and sometimes causing fires. Therefore, the use of straw has always been vigorously advocated by the environmental protection, agriculture and forestry departments; currently, the scope of straw utilization is very narrow, such as manufacturing flooring, straw weaving, etc., but the ut...
