Pre-buried paddy field water and fertilizer monitoring system

Abstract

The invention discloses a pre-buried paddy field water and fertilizer monitoring system which comprises a pre-buried box, a cover plate arranged on the pre-buried box, a water level monitoring system,a layered water pipe system, a conductivity sensor system and a manual water taking system, wherein the pre-buried box comprises a field reduction box and a component placement box, and the field reduction box and the bottom of the component placement box are integrated, and a partition plate is arranged at the joint of the field reduction box and the component placement box. According to the method, the mode of the device to a paddy field overcome the difficulty of field sampling, and water can be simply and conveniently taken from the paddy field in a layered mode. Meanwhile, the vertical migration loss and the field surface loss of the paddy field fertilizer with water can be automatically monitored in real time, and the underground water level of a paddy field can be monitored in realtime. The paddy field water and fertilizer data can be automatically sent to a mobile phone or a computer terminal through solar power supply. The system has the advantages of being energy-saving, environment-friendly, high in automation degree, and capable of being used for test research and scale planting. The accuracy can be calibrated.

Description

technical field [0001] The invention belongs to the technical field of agricultural water and soil engineering, in particular to a pre-embedded paddy field water and fertilizer monitoring system. Background technique [0002] As the grain variety with the largest planting area in my country, rice has always been in a dominant position in my country's grain production and consumption. The rice production process consumes a lot of water and frequently exchanges water with the outside world. The irrigation water of rice fields accounts for more than 60% of the agricultural water consumption. Due to the abundance of water in paddy fields, the migration and loss of fertilizers with water is more frequent than that in dry land. The loss of fertilizer with water includes not only the loss with surface runoff, but also the loss with vertical migration of water. The groundwater level of conventional paddy fields is generally high and changes frequently during the whole growth perio...

AI Technical Summary

Problems solved by technology

[0003] Due to the difficulty of sampling in rice field experiments and the lack of continuity, the current research focuses on lysimeter plot experiments. Even field experiments are mostly focused on the study of water and fertilizer loss in surface runoff. It is difficult to take samples to study the vertical migration of water and fertilizer in the field.
