Water and fertilizer integrated lysimeter measuring system adopting Internet of Things

Abstract

The invention discloses a water and fertilizer integrated lysimeter measuring system adopting the Internet of Things. The water and fertilizer integrated lysimeter measuring system is characterized by comprising a mechanical composition part, an Internet of Things core module, a data transmission module, a data detection module and a remote host computer module. Remote acquisition of field data is realized; environmental information of different soil depths affecting crop growth is acquired through layered sensors, and the acquired data are accurate and reliable; the acquired data are stored in a database, and follow-up data analysis is facilitated; fertilizer consumption of crop root systems at different depths can be measured regularly, and water and fertilizer study is facilitated.

Description

technical field [0001] The invention belongs to the intersecting fields of modern agricultural technology and the Internet of Things, is a combination of the information technology of the Internet of Things and the modern agricultural technology, and particularly relates to an integrated water and fertilizer lysimeter measurement system of the Internet of Things. Background technique [0002] Water and fertilizer integration technology is a key factor in modern intensive irrigation agriculture, especially in China, a large agricultural country. On the one hand, the contradiction between the huge amount of agricultural water consumption and the shortage of water resources requires the development of water-saving agriculture, the measurement of crop water evaporation, research Water consumption is used to improve the utilization of water resources in agriculture, which is of great significance to water conservation; on the other hand, as a country with a large consumption of che...
