specific Embodiment

[0078] The following will be described in detail in conjunction with specific embodiments. The experimental methods for which specific conditions are not indicated in the examples are implemented according to conventional conditions, such as the conditions described in literature, books or the method recommended by the manufacturer.

[0079] It should be noted that the contents in the following examples are all in mass percent.

Embodiment 1

[0081] The matching degree of fertilizer (15-15-15) and cucumber melon period

[0082] (1) Obtain alkaline hydrolysis nitrogen content, available phosphorus content and available potassium content in the soil of embodiment 1 by alkaline hydrolysis diffusion method, sodium bicarbonate extraction-molybdenum antimony anti-colorimetric method and ammonium acetate extraction-flame photometer method respectively . The alkaline hydrolysis nitrogen content of Example 1 is 80ppm, the available phosphorus content is 60ppm, and the available potassium content is 90ppm. By querying the soil nutrient content grade table, it is determined that the grade of alkaline hydrolyzed nitrogen content in the soil of Example 1 is grade 4, the grade of available phosphorus content is grade 1, and the grade of available potassium content is grade 4. Obtain the nutrient data (in terms of mass percentage composition) of fertilizer (15-15-15) by fertilizer composition table: nitrogen content is 15%, and ...

Embodiment 2

[0088] The matching degree of fertilizer (15-5-25) and cucumber melon period

[0089] (1) Obtain alkaline hydrolysis nitrogen content, available phosphorus content and available potassium content in the soil of embodiment 2 by alkaline hydrolysis diffusion method, sodium bicarbonate extraction-molybdenum antimony anti-colorimetric method and ammonium acetate extraction-flame photometer method respectively . The alkaline hydrolysis nitrogen content of Example 2 is 80ppm, the available phosphorus content is 60ppm, and the available potassium content is 90ppm. The soil nutrient data of embodiment 2 is identical with embodiment 1. Therefore, similarly, C=0.2 and D=0 in Example 2. Obtain the nutrient data (in terms of mass percentage composition) of fertilizer (15-5-25) by fertilizer composition table: nitrogen content is 15%, and phosphorus content is 5%, and potassium content is 25%; Fertilizer data for melon crops (in terms of mass ratio, and has been normalized): the ratio o...

Abstract

The invention relates to a method and device for analyzing the fertilizer and crop matching degree. The method for analyzing the fertilizer and crop matching degree comprises the following steps: acquiring soil nutrient data, fertilizer nutrient data and crop fertilizer requirement data; determining a soil correction coefficient according to a phosphorus and potassium nutrient constant monitoring principle and the soil nutrient data; calculating the fertilizer and the crop matching rate according to the crop fertilizer requirement data, the fertilizer nutrient data and the soil correction coefficient; obtaining the fertilizer and crop matching degree according to the matching rate. By adopting the method for the fertilizer and crop matching degree, the fertilizer and crop matching degree can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method and device for analyzing the matching degree of fertilizers and crops. Background technique [0002] Fertilizers refer to organic, inorganic, microbial and their mixture materials used to provide, maintain or improve plant nutrition and soil physical and chemical properties and biological activity, increase the yield of agricultural products, or improve the quality of agricultural products, or enhance plant stress resistance . [0003] At present, some growers are relatively blind in the selection of fertilizers, and the quality of crops is often low due to unreasonable selection of fertilizers. Contents of the invention [0004] Based on this, it is necessary to provide an analysis method for the matching degree of fertilizers and crops, so as to select suitable fertilizers for crops. [0005] A method for analyzing the matching degree of fertilizers and crops, ...
