In the future, the majority of farmers directly in the process of fertilization of crops, accurate, rapid, real-time detection of crop nitrogen status and the growing dynamic and timely access to crops, the demand for fertilizer, because of the need fertilizer, thereby saving the cost of fertilizer, fertilizer to achieve fine of.
Recently, biological systems engineering from Zhejiang University and Food Science, Dr. Nie Pengcheng, a team led by Professor He Yong, successfully developed a rice-based spectroscopy leaf nitrogen analyzer. The instrument can directly measure the nitrogen content in rice leaves, high precision, refinement of fertilizer in the agricultural process, not only help to save fertilizer costs and to reduce the excessive use of fertilizers and the environmental degradation caused by soil and water resources pollution, has a very high value.
Nitrogen is one of the necessary nutrients in rice, but too much nitrogen, likely to cause groundwater pollution, how to ensure high quality crops, while crop production but also to prevent the environmental pollution, governments, agronomists and producers facing common problems. The key to solve this problem on the crop nitrogen content capture real-time online detection technology, real-time access to plant nitrogen content in the growth process, in order to achieve on-demand precision fertilization. While abroad, mature technology, has introduced a number of results, but the high cost of foreign equipment, promotion difficult, not suitable for rapid field or can not be directly measured plant nitrogen content.
Zhejiang University, Rice leaf nitrogen analyzer developed, in large measure to solve this problem. At present, the instrument has been successfully entered the market, has become a measure of plant chlorophyll content, nitrogen content of plant nutrients Speed ​​Meter. (Ao soft)
