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LF3 3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 5 7%。在一次性施肥条件下 ,小麦产量最高 ,对肥料氮的利用率达 4 0 8% ,比同类型复合肥高 5Nitrogen releasing of fertilizers was studied The results showed that nitrogen releasing of stable organic inorganic compound fertilizer(LF 3 3) was slower at early stage after the fertilizer applied to soil,this would be beneficial to crop growth in seedling stage Ammonia volatilization amount from ground surface was apparently lower than the other similar compound fertilizers;as compared with urea,ammonia volatilization inhibition rate was 57% When LF 3 3 was appliecl one time,the wheat yield was the highest,nitrogen utilization rate of the fertilizer was 40 8%,and it was 5 3% higher than the other similar compound fertilizers
