| 摘 要： | 高浓度、复合、专用、长效是肥料发展的必然趋势。长效专用复混肥是在普通专用复混肥基础上,适当调整其氮、磷、钾的配比,并加入抑制剂而制成。该产品已多家肥厂生产,成本比普通专用肥增加35元/t,己在辽宁、山东、新疆等地推广应用,供试作物有玉米、小麦、水稻、棉花等,与同等养分或同等价格的普通专用肥相比,可增产10-15%,肥料利用率提高20%以上,并可达到基肥一次施入,免除追肥,较好地解决了农业高新技术不便追肥的难题。

The Development, Manufacturing and Application of Controlled-Release-Compound-Fertilizer |
| |
| Abstract: | Controlled-release compound fertilizer is manufactured basing on special-purpose of compound fertilizer, in which the ratios of NPK should be adjusted properly and mixed with some inhibitor. This product has been manufactured by many plants with the operating costs increased by 35 yuan/ton. It has been widely applied in many provinces such as Liaoning, Shandong, Xinjiang etc. and the application crops include maize, wheat, rice, cotton etc. Compared with using other special-purpose fertilizer, using this product can increase cropyied by 10%-15%, the utilization rate of the fertilizer can also be increased by more than 20%. |
