Based on the near-infrared soil organic matter content measurement system research

For precision agriculture has become the new trend of agricultural development of the present situation, this paper introduces a kind of on-line soil component content detection system based on the near infrared technology. From the characteristics of near infrared technology, carry on the in-depth analysis and research of the near-infrared technology, this paper expounds the principle of near-infrared detection and analyses the huge advantage of near infrared technology application in soil component content detection. Based on this technology designed a set of near infrared soil component content online field testing system, used for soil organic matter and total nitrogen content detection. Analysis and experiments show that, with the traditional laboratory chemical testing technology, the system has advantages of small size, low cost, no pollution, portable, nondestructive, etc, greatly improves the working efficiency of the agricultural science and technology personnel, reduces the working intensity, that do not have the laboratory condition of rural also can be easily for testing.
