Embodiment 1

[0033] like figure 1 As shown, a test paper box for rapid detection of compost maturity, the test paper box includes a ninhydrin test paper 1 , a colorimetric card 2 and a detection container 3 .

[0034] The ninhydrin test paper 1 is a test paper loaded with ninhydrin; the ninhydrin test paper includes a diffusion section 1a and a color development section 1b, the diffusion section 1a is located at the end of the test paper and is not loaded with reagents, and the color development section 1b is located in the diffusion section Above 1a and loaded with ninhydrin. The preparation method of the ninhydrin test paper is as follows: a ninhydrin ethanol solution with a mass concentration of 0.5% is immersed in the color developing section 1b, and then dried.

[0035] The colorimetric card 2 has several sheets, the color of the colorimetric card is blue-violet, and the colorimetric cards are arranged in order according to the degree of blue-violet; The blue-purple produced by the ...

Embodiment 2

[0038] To test the compost maturity of chicken manure in a chicken farm:

[0039] (1) Take the chicken manure compost that has been composted for 5 days (referred to as sample 1), put it into the testing container (the amount of chicken manure compost needs to reach the minimum mark), then add water to the maximum mark, stir to fully soak in water Compost to be tested for 30min;

[0040] (2) Take the ninhydrin test paper and put it into the detection container, so that the diffusion section at the end of the ninhydrin test paper is immersed in the soaking liquid of the compost to be tested for 10 minutes;

[0041](3) Take out the ninhydrin test paper, then dry it with hot air (hot air from an electric hair dryer, temperature controlled at 60-120°C) ninhydrin test paper, and then compare the color on the ninhydrin test paper with the color of the colorimetric card to determine the The colorimetric card with the closest color on the ninhydrin test paper is the colorimetric card...

Abstract

The invention discloses a compost maturity rapid detection test paper box and a use method thereof. The test paper box comprises ninhydrin test paper, a colorimetric card and a detection container, wherein the ninhydrin test paper is ninhydrin-loaded test paper, wherein the number of the colorimetric cards is multiple, the color of the colorimetric cards is bluish violet, the colorimetric cards are sequentially arranged according to the depth degree of bluish violet, and bluish violet of the colorimetric cards is determined according to bluish violet generated by reaction of amino acid solutions with different concentrations and ninhydrin; and the detection container is provided with volume scales. The compost maturity detection method can be used for simply, conveniently and quickly detecting the maturity on site, is accurate, stable and reliable in maturity detection result and more flexible to use, and is suitable for detecting the maturity of various composts.

Description

technical field [0001] The invention belongs to the technical field of composting, and in particular relates to a test paper box for rapid detection of compost maturity and a method for using the same. Background technique [0002] With the development of modern economy, especially agriculture, a large amount of organic solid waste is produced. At present, the common agricultural wastes include livestock and poultry manure, crop straw, etc., as well as green waste generated by forestry. In order to achieve the purpose of circular development, these agricultural wastes and forestry wastes are generally treated by composting. Composting can not only make the pathogenic bacteria in the waste harmless through high-temperature fermentation under the action of microorganisms, humus and stabilize the organic matter, and finally reach maturity, but also can be further processed into organic pollution-free fertilizers. [0003] For composting, the composting process and maturity of...
