硫酸铵肥在北疆棉花种植中的应用效果初探

Application Effect of Ammonium Sulphate Fertilizer on Cotton Plantation in Northern Xinjiang, China

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。

Abstract: 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% (P < 0.01) by applying ammonium sulfate fertilizer, but there was no significant difference in chlorophyll, leaf area between ammonium sulfate fertilizer treatments and CK during cotton growth period.
