新型缓控释增效肥研究进展和发展前景

传统肥料面临着利用率低、产能过剩等问题,新型缓控释肥通过新型包膜材料或者纳米技术,实现养分释放速度的可控性;通过添加信号物质,实现植物和化肥的互动,将植物养分需求规律作为主导因素,实现肥料的按需供给,达到减少化肥用量,提高肥料利用效率的目的。从定义、研发背景、分类及发展趋势等方面介绍了新型缓控释肥的研究进展,并对其未来发展进行了展望。

Researching Progress and Developing Prospect for New Slow/ Controlled Releasing Fertilizer

Abstract: Traditional fertilizers are faced with such problems as low utilization rate and excess capacity. Through new envelope materials or nanotechnology, the new slow/controlled releasing fertilizers achieved controllable release rate of nutrients by adding the signal substance, and realized the interaction between plants and chemical fertilizer. Taking the regularity of nutrient demand of plants as the dominant factor, it could provide nutrients to the crop, to reduce the amount of fertilizer and improve the utilization efficiency of fertilizer. The new slow/controlled release fertilizers definition, developed background, classification and trend were introduced, and its development in the future was prospected.
