摘要： 通过对肥料氮素释放的研究看出，稳定型有机无机复合肥LF-施入土壤初期氮释放缓慢，对作物苗期生长有利，10d内地表氨挥发量明显低于同类型复合肥，与尿素相比氨挥发抑制率达57%。在一次性施肥条件下，小麦产量最高，对肥料氮的利用率达40.8%，比同类型复合肥高5个百分点。

Abstract: Nitrogen releasing of fertilizers was studied1The results showed that nitrogen releasing of stable organic-inorganic compound fert ilizer（LF3-3) was slower at early stage af ter the fertilizer applied to soil, this would be beneficial to crop growth in seedling stage1Ammonia volatilization amount from ground surface was apparently low er than the other similar compound fert ilizers; as compared with urea, ammonia volatilizat ion-inhibit ion rate was 57%.When LF3-3 was applieclone time, the wheat y ield was the highest, nitrogen ut ilizat ion rate of the fertilizer was 40.8%, and it was 5.3% hig her than the other similar compound fertilizers.
