摘要: 采用浸水释放试验和苹果田间试验研究了有机高分子聚合物包膜控释氮肥的释放特征, 并以
普通尿素为对照, 研究了包膜控释氮肥对苹果产量、品质的影响。浸水试验结果表明, 控释氮肥的释放分
为逐渐增大、释放高峰、逐渐减小3个阶段; 田间试验结果表明, 与普通尿素相比, 控释肥的氮素释放模
式与苹果树对氮素的需求相一致, 增加了叶片叶绿素、叶片和枝条中氮素的含量, 提高了果实产量、糖、
钙、维生素C含量, 降低了氮含量。

Abstract:

Nitrogen release experiment and field experimentwere conducted to study release characteris
tics of the controlled2release fertilizer (CRF) coated with hydrophobic material (organic macromolecule poly
mer) and its effects on yield and quality of app le as compared to common urea. Three release stages were
found in nitrogen release curve: increasing stage, peak stage, decreasing stage. Field experiment showed that
controlled-release pattern of CRF met the nitrogen requirements of app le trees, and then p romoted its growth,
yield and quality.
