摘要

尽管人们已经使用了各种各样的物质来覆盖化学肥料以减缓或控制它们的释放，但找到最佳的物质和最佳的性能条件仍然是必要的。采用热解法制备的4种生物油包被颗粒化肥（N20、P5、K10），并对包被效果进行比较。秸秆生物油在化肥表面具有较好的包覆性能。IC分析结果表明，秸秆生物油包膜化肥在前24 h的养分释放量较芯肥减少了78.5%。为寻找包膜工艺的最佳条件，在400℃、500℃和600℃三种不同温度下对化肥颗粒进行秸秆生物油包膜。结果表明，600℃秸秆生物油包膜能改善覆盖层质量。图形抽象

Influence of bio-oil on slow-release of nutrients from chemical fertilizers

Although various substances have been used to coat chemical fertilizers to slow or control their release, finding the best substance and optimal performance conditions is still essential. The granular chemical fertilizer (N20, P5, K10) was coated using four kinds of bio-oil (prepared by the pyrolysis method) and the results were compared. Straw bio-oil had better coating properties on the surface of the chemical fertilizer. According to the IC analysis results, the amount of nutrients released from chemical fertilizer coated by straw bio-oil decreased by 78.5% in the first 24 h in comparison with the core fertilizer. To find better conditions for the coating process, chemical fertilizer granules were coated with straw bio-oil at three different temperatures (400 ℃, 500℃, and 600 ℃). Finally, the results showed that coating chemical fertilizer with straw bio-oil at 600 ℃ could improve the quality of the covering layer.
