摘要:

缓/控释化学肥料是一种能提高化肥利用率的生态肥料，其控释机制能使化肥养分缓慢释放，延长植物养分吸收周期，从而降低化肥施用量。介绍了近年来缓/控释化肥研究进展。

Abstract:

Slow/controlled release chemical fertilizer is an eco-fertilizer capable of improving its utilization rate.Its controlled release mechanism can slow the release of chemical ertilizer nutrients, prolong the nutrient absorption cycle of plant,and thus reduce the application amount of the chemical fertilizer. The research progress of slow/controlled-release fertilizers in recent years is introduced in this paper.
