Due to the lack of soil information, in order to increase the output of agricultural products, the vast majority of farmer friends generally suffer from blind and excessive fertilization during the farming process, which not only results in soil compaction and degeneration, but also causes serious environmental pollution. Research and design of soil information collection systems have become the primary issues in the field of agricultural production in various countries.
Soil agrochemical information collection system abbreviation agrochemical information collection system, is a kind of public opinion data processing equipment, mainly using a number of GPRS wireless data terminals (DTU) provided by the GPRS service, the data is transmitted to a fixed data processing center. When the GPRS wireless terminal enters the GPRS network, data in the form of an IP packet is automatically attached to the Internet. Therefore, this transmission method does not require the GPRS provider to provide more services and support, and it can transmit data from any GPRS coverage area to the center.
The system is mainly divided into soil information sensors, microcontroller control unit (MCU) and GPRS module units, data center software 3 parts through the signal generated by the soil information sensor after a corresponding transformation to the MCU and GPRS module unit, after a simple microcontroller processing, The GPRS module is connected to the GPRS network and sent to the Internet network by the GPRS network. Data center computers access the Internet to get data.
The system realizes wireless transmission of GPRS soil data. Based on the design of 51 MCU GPRS terminal data and system programmable function, it saves product cost, streamlines the hardware structure, fully utilizes the resources of the data center desktop computer, and improves soil information collection. The efficiency and effectiveness of the system provide a powerful guarantee for operators to understand the soil conditions in a timely manner.

PTFE Thread Seal Tape
PTFE Thread seal tape (also known as PTFE tape or plumber's tape) is a polytetrafluoroethylene (PTFE) film for use in sealing pipe threads.
PTFE Thread seal tape lubricates allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed. The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten,and instead making it easier to tighten.
Typically the tape is wrapped around a pipe's thread three times before it is screwed into place. It is commonly used commercially in applications including pressurized water systems, central heating systems, and air compression equipment.
