preparation example Construction

[0024] (1) Preparation of the test sample solution: Weigh 5-8g of the sample, place it in a 400ml tall beaker, add 30ml of hydrochloric acid and 10ml of nitric acid, cover it with a watch glass and heat it on an electric heating plate. Remove the watch glass and continue heating to evaporate all the acid to nearly dryness to drive off the nitric acid. After cooling, add 50ml of hydrochloric acid solution, heat to dissolve, add 50ml of hydrochloric acid solution after cooling to room temperature, heat to dissolve, transfer to a 250ml volumetric flask after cooling to room temperature, dilute with water to the mark, mix well, dry filter, discard the first few milliliters of filtrate, stand-by.

[0025] (2) Preparation of blank solution: Except that no sample is added, other steps are the same as the preparation of sample solution.

[0026](3) Determination of heavy metal content: A: adopt spectrophotometry, according to Lambert Beer's law, at a certain wavelength, the absorbanc...

Abstract

The invention discloses a method for detecting environmental pollution caused by fertilization, and establishes a critical threshold model of organic fertilizer environmental pollution. The amount of loss in the environment, combined with the crop's demand for nutrients and various heavy metal components, is used to calculate the amount of organic fertilizer needed to meet the growth of crops, and predict whether the amount of organic fertilizer will bring heavy metal pollution to the planted soil. The method of the present invention is predictive, and the accuracy of evaluating the heavy metal pollution caused by fertilization is as high as 100%, which can be used to predict and adjust the fertilization plan before fertilization, so as to avoid the heavy metal pollution that fertilization may bring to the soil, and Nitrogen saturation and P pollution.

Description

technical field [0001] The invention relates to the field of organic agriculture, in particular to a method for detecting critical thresholds of environmental pollution caused by the application of chicken manure, pig manure, organic fertilizers and the like and an application thereof. Background technique [0002] my country's animal husbandry produces the most fecal waste in the world, and a large part of it has not been properly treated and utilized, which has caused huge pollution to our country's ecological environment. It is an important means of reuse to process and reprocess livestock and poultry manure and make it into organic fertilizer for agricultural production. Organic fertilizer is an important material basis and an important fertilizer in agricultural production. The use of organic fertilizers for agricultural production is not only the material and energy cycle of agriculture itself, but also an effective way to purify the human environment and reuse resour...
