Abstract

The invention relates to the technical field of plants and concretely relates to method and apparatus for detecting plant nitrogen content and an electronic device. The method detecting plant nitrogen content comprises steps of extracting a three-primary color proportion value of each pixel in a to-be-analyzed image, adding green proportion values of the three-primary color proportion values of a plurality of pixels to achieve a green proportion value total, and achieving a corresponding nitrogen content corresponding to the green proportion value total according to the green proportion value total through a preset mathematic model, and further analyzing the plant image to achieve a nitrogen content condition of the plant. Destructive sampling to the plant can be achieved; and the method is high efficient and quick.

Description

technical field [0001] The invention relates to the technical field of plants, in particular to a method, device and electronic equipment for detecting nitrogen content in plants. Background technique [0002] Rice is the main food crop in my country and occupies an important position in China's food production. Rice production is not only related to my country's food production, but also related to economic development and social stability. Nitrogen nutrient management significantly affects the growth and yield of rice, and is the key to stable and high yield of rice. The nitrogen nutrition diagnosis and nitrogen fertilizer recommendation of rice are based on destructive sampling in the field. Although the accuracy is high, it is time-consuming and labor-intensive, which is not conducive to popularization and application. Therefore, it is very necessary to adopt a method that can obtain the nitrogen content of plants (rice) in real time without destructive sampling. Con...
