Abstract

The invention relates to the technical field of agriculture measure, especially to a soil moisture distribution measuring system and a measuring method. The soil moisture distribution measuring system comprises a soil moisture sensor, a transmission apparatus, a control acquisition apparatus, a bottom pipe underground, and a first side pipe and a second side pipe both partially underground; the transmission apparatus is driven by the control acquisition apparatus, and thereby the soil moisture sensor travels in a pipeline formed by the bottom pipe, the first side pipe and the second side pipe under traction of a cable, and the detection of soil moisture nearby a plant root zone is realized, then the measured value is transmitted to the control acquisition apparatus by the cable, and thereby the measure and monitor of the moisture at different positions of the plant root zone are carried out by the control acquisition apparatus. The soil moisture distribution measuring system and the soil moisture distribution measuring method using the system have beneficial effects of no damage to plants or soil structure, a large measuring area, no phenomenon of mutual interference between sensor probes, and accurate and intelligent measurement.

Description

technical field [0001] The invention relates to the technical field of agricultural measurement, in particular to a soil moisture distribution measurement system and a measurement method. Background technique [0002] Water is the lifeblood of plant growth and the basic prerequisite for ensuring stable and increased grain production in my country. However, our country lacks fresh water resources, and efficient and rational use of water resources is a very important task in modern agricultural production. Measuring and monitoring the distribution of soil moisture in the root zone of plants can effectively guide precision water-saving irrigation. At the same time, the distribution of soil moisture in the root zone of plants is an important hydrological variable for successful climate and environmental prediction. According to the soil moisture content of plant root zone Establishing mathematical models related to agriculture, hydrology and meteorology is of great significance...
