【摘要】 以K₂SO₄为原料,采用混合成囊法制备了缓释肥微囊粒子（D粒子）。混合成囊法制备的微囊缓释性好,有效成囊率高（大于90%）,囊心有效成分含量高（大于95%）,工艺简单,成本低廉。试验结果表明,缓释肥处理比常规施肥处理产量和产值分别提高了15.3%、13.2%,差异达极显著水平。更多还原

【Abstract】 The slow release fertilizer microcapsule D particle is prepared by mix embedded microcapsule method with the K₂SO₄ as material.The results show the microcapsule with good released characteristic, higher yield（more than 90%）,higher effective ingredient content of microcapsule body（more than 95%）, and simple processing technology of lower cost.The output and production value with the application of the slow release fertilizer treatment are increased 15.3%and 13.2%respectively,compared with those of the common fertilizer treatment,with the significant differences.更多还原
