摘　　要：在北疆石河子植棉垦区,以硫酸铵肥为研究对象,探讨利用煤电厂废弃物硫酸铵替代尿素施肥的可能性。初步研究结果表明,硫酸铵肥对棉花具有极显著的增产作用,这种作用并不随硫酸铵肥用量增加而显著增加;在同等施氮量条件下,施用硫酸铵肥使棉花增产47%(P <0.01);但棉花生育期硫酸铵肥处理的棉花叶绿素、叶面积与对照比差异不显著。The possibility of using ammonium sulfate fertilizer from coal power plant waste to replace urea fertilization was discussed in Shihezi cotton cultivation area of northern Xinjiang in China. The pre-liminary results showed that ammonium sulfate fertilizer had a very significant effect on cotton yield increase. This effect did not increase significantly with the increase of ammonium sulfate ap-plication rate;under the same nitrogen application rate, the yield of cotton increased 47% .
