【摘要】：针对目前国内传统施肥方式中,存在基肥施用量大,盲目施肥,氮、磷、钾单一品种化肥用量过多,导致土壤肥力退化、土壤养分不均衡,影响到农作物增收等现状,借助物联网技术、近红外分析技术、现代通信技术和无线网络技术,选用近红外分析技术和基于FFT算法及小波变换的光谱微弱信号处理方法,实现实时监测土壤养分的变化,全面而准确地掌握农业土壤养分情况,并智能控制自动施肥执行端施肥。为此,进行了样机试制,并运用于不同的农业土壤,包括褐土、红土、黑土等进行养分监测和施肥试验。结果表明:农业土壤养分监测及施肥系统可稳定运行,精准施肥,能满足不同农业土壤的精确施肥。本系统可指导科学施肥,提高农业生产的施肥水平,减少农业污染。
[Abstract]:In the traditional fertilization methods in China, there are many kinds of fertilizer, such as large amount of base fertilizer, blind fertilization, excessive amount of nitrogen, phosphorus and potassium, which lead to the degradation of soil fertility, the imbalance of soil nutrients, and affect the increase of crop income, etc. With the help of Internet of things technology, near infrared analysis technology, modern communication technology and wireless network technology, using near infrared analysis technology and spectral weak signal processing method based on FFT algorithm and wavelet transform, the change of soil nutrients can be monitored in real time. Fully and accurately understand the situation of agricultural soil nutrients, and intelligent control of automatic fertilization implementation end fertilization. Therefore, a prototype was developed and applied to different agricultural soils, including cinnamon soil, red soil and black soil, for nutrient monitoring and fertilization. The results showed that the nutrient monitoring and fertilization system of agricultural soil could operate stably, and the precision fertilization could satisfy the precision fertilization of different agricultural soils. The system can guide scientific fertilization, improve the level of fertilization in agricultural production and reduce agricultural pollution.
