摘　　要：将鲜稻秆、麦秸秆复配氮磷钾养分,采用堆压搅碎和孔磨辊压工艺试制秸混颗粒肥,并采用大田试验,测试了其在杂交水稻内5优8015和小麦扬麦20上的应用效果。结果表明,该秸混颗粒肥有机质含量、氮磷钾含量、pH值、粒性、抗压强度、膨胀率及保水率等理化特性均达到肥料使用的要求;底施秸混颗粒肥再追施1次氮肥的扬麦20和内5优8015,产量与高产施肥对照持平;秸混颗粒肥N和P2O5偏生产力在扬麦20和内5优5015上均显著提高,而K2O的偏生产力变化趋势有差异。The straw-mixed granular fertilizer was made by blending the fresh straw of rice(Oryza Sativa L.) and wheat(Triticum aestivum L.)with nitrogen, phosphorus and potassium nutrients by stir chopping and template rolling. A field experiment was carried out to test the fertilizer’s application effect on Nei 5 you 8015 and Yangmai 20. The results showed that, the physicochemical properties of the straw granular fertilizer, such as organic matter content, nitrogen, phosphorus and potassium content, pH value, granularity,compressive strength, swelling rate and water retention rate, met or exceeded the relevant National Standards. Under base applying the straw granular fertilizer and topdressing nitrogen fertilizer at tillering stage, the yields of Yangmai 20 and Nei 5 you 8015 were the same as those of the high-yielding fertilizer application. The partial productivity of N and P2O5 increased significantly in Yangmai 20 and Nei 5 you 5015, but the K2O was different.
