Recently, many customers called to inquire about our company's regular positioning of the soil moisture measuring instrument. During the communication process, because of the infusion of other manufacturers who did not complete the timing positioning technology, I felt that the customer was positioning the soil moisture velocity measurement The instrument has been misunderstood, the meaning that the customer understands is:

Timing: In the instrument can be set time or time for real-time display and storage (this understanding is correct)

Positioning: The instrument is installed in a place that does not move, and the position is fixed there. It means positioning (this understanding is wrong)

The correct meaning of timed positioning soil moisture meter is:

Timing: There is time for real-time display and storage in the instrument

Positioning: The integrated GPS module in the instrument can display and store longitude and latitude at any time. Each stored parameter can display and store the position information (latitude, longitude) of the tested soil.

The background and significance of the development of a time-based soil moisture measuring instrument:

The development of international agriculture has experienced three major stages of development: primitive agriculture, traditional agriculture and modern agriculture. Since this century, people have proposed a series of alternative agricultural countermeasures, such as regression agriculture, ecological agriculture, organic agriculture, and comprehensive agriculture.

The core of precision agriculture refers to the real-time acquisition of information on the soil and crops in each plot of the plot, the reasons for diagnosing crop growth and yield in terms of space, and making decisions for each cell, accurately on each plot. Irrigation, fertilization, and spraying are used to maximize the use of water, fertilizer, and pesticides, increase production, and reduce environmental pollution.

Since the 1990s, with the development of technologies such as Global Positioning System (GPS), Geographic Information System (GIS), Remote Sensing (RS), Variable Disposal Equipment (VRT), and Decision Support System (DSS), precision agriculture is used as The intensive agriculture of science and technology has come out, and has become a hot area of ​​sustainable agricultural development.

In recent years, some technologically advanced farms in the United States and Europe have entered a medium-scale implementation phase in precision agriculture. Some farms installed telemetering sensor devices, GPS instruments, microcomputers, chemical fertilizers, pesticides, etc. on tractors. While driving in the field of tractors, sensors were used to obtain crop growth status information. GPS gave precise positioning. Computer software systems. Stored in advance in the GIS, and related parameters such as the soil of the plot, crop varieties, and cultivation measures completed during the growth stage, call out a quick diagnosis and decision model, and provide irrigation, fertilization, insecticide, and herbicide formulations. Take farming measures on the spot.

The practice of foreign precision agriculture shows that: Fine agriculture not only has important economic benefits, but the detailed farming information it obtains helps solve many unknown problems. The fundamental benefits of precision agriculture are reflected in the reduction of the production costs of crops and the risk of overuse of agrochemical products. The revolutionary significance of the study of "precise agriculture" is to propose a new technology idea for modern agriculture and put it into practice. The development prospect has been widely recognized in the world.
