Abstract

The invention relates to an open type soil moisture content monitoring and forecasting system, which mainly comprises a monitoring part and a forecasting part, wherein the monitoring part is composed of a moisture sensor, a data collector and a wireless transmitter; the moisture sensor is buried into soil layers with different depths so as to measure the moisture content of a soil profile of some measuring point at a crop root area; the moisture data acquired by the data collector and the moisture sensor are transmitted to the data receiver through a wireless transmitter; the forecasting part is composed of a data receiver, a data central processor and a transmitting hub; the data receiver is used for receiving the soil moisture data of the moisture sensor at the monitoring point; the soil moisture is transmitted to the data central processor; the input soil moisture data, the weather forecast data, the artificially collected crop moisture physical indexes and crop desired water data are processed so as to obtain the soil moisture content forecast data to the transmitting hub; the information of the soil moisture content forecast data are broadcast in time through television stations, radio stations, weather screens, cell phone short messages and faxes, thereby conducting to irrigate the crops in time.

Description

technical field [0001] The invention relates to the field of farmland water conservancy, and is a soil moisture monitoring and forecasting system. Background technique [0002] Moisture refers to the humidity of the soil suitable for plant growth and development; Moisture refers to the condition of soil moisture. Soil moisture is the degree of dryness and wetness of the soil, that is, the actual water content of the soil, which can be expressed as a percentage of the soil water content in the dry soil weight, soil water content = water weight / dry soil weight × 100%; it can also be expressed as the soil water content It is expressed as a percentage of field water capacity, or as a percentage of saturated water. Soil water is the main source for plants to absorb water (except for hydroponic plants), and plants can also directly absorb a small amount of water that falls on the leaves. The main sources of soil water are precipitation and irrigation water, which participate i...
