In recent years, the issue of human “hidden hunger†has received much attention. Due to the prevalence of trace element deficiency in cultivated soils in China, the lack of related micro-elements in food leads to the imbalance of human nutrition. According to statistics, about 70% of chronic diseases are related to human “hidden hungerâ€. Scientific application of medium and micro-fertilizer can not only reduce the disease yield reduction caused by crop imbalance, but also increase the utilization rate of nitrogen, phosphorus and potassium nutrients.
The development of micro-fertilizer has become an important breakthrough in the transformation and upgrading of the fertilizer industry. In recent years, zero growth of fertilizer use, balanced fertilization, and soil remediation have also provided opportunities for the development of medium and micro fertilizers.
At present, there are bottlenecks in the key technologies of China's medium and micro-fertilizers, especially the development of cheap and efficient chelating agents; enterprise R&D and product services are imperfect, users are not guided by the use of training, and the market is not adequately cultivated; farmers have a role in the micro-fertilizer and The understanding of scientific application is still insufficient.
In the face of the broad market of micro-fertilizers, scientific research institutions should strengthen production, research and research reserves, and overcome key technologies; enterprises should activate market demand, achieve equal emphasis on product and service, and promote the transformation of agrochemical services; all parties should strengthen publicity and training for farmers.
