Abstract
The present invention proposes a method for predicting soil moisture and total nitrogen content in real time. The soil samples are collected for data, and the absorbance values of the moisture sensitive wavelength and the nitrogen sensitive wavelength are used as input independent variables to establish the prediction of soil total nitrogen content in a water-containing state. Model; according to the model to establish a multi-output variable prediction model; according to the output of the prediction model to predict soil moisture and total nitrogen content. Based on different types of soils, the present invention establishes a general-purpose spectral prediction model by selecting sensitive wavelengths, which can realize the prediction of moisture and total nitrogen content in different types of soils without complex spectral data preprocessing and moisture correction. . Compared with collecting samples and then analyzing them, the present invention can simultaneously and continuously output moisture and total nitrogen content while continuously collecting spectral information on site, ensuring real-time, authenticity and sustainability of data, and expanding soil moisture and total nitrogen content. In-situ, real-time and continuous monitoring applications of total nitrogen content.
Description
technical field [0001] The present application relates to the field of soil detection and analysis, in particular to a method for real-time prediction of soil moisture and total nitrogen content. Background technique [0002] Moisture and nitrogen in the soil play a vital role in crop growth and fruit development. Understanding the soil water and total nitrogen content, and rational irrigation and fertilization according to the site can reduce economic losses and reduce the adverse impact on the environment caused by excessive fertilization. Therefore, it is of great practical significance to develop rapid, real-time, in-situ, continuous and pollution-free detection methods. [0003] Near-infrared spectroscopy is an advanced analytical technique that integrates computer science, spectroscopy, and chemometrics. Because of its non-destructive, rapid and non-polluting characteristics, its application in the agricultural field has received extensive attention and research in r...
