利用自然界大量存在的木质素和经造纸工艺得到的木质素为原料,利用转鼓包膜法制备了新型的包膜缓释复合肥,并通过不同温度和pH值的静水实验探究肥料养分的规律,草莓的田间试验探究肥料的实际使用效果。实验结果表明,使用工业木质素包膜的复合肥,初期养分释放率为14.58%,28d总养分释放率达58.12%,满足国标(GBT23348-2009)的要求,并且能够极显著地提高草莓的产量,具有良好的开发前景。
Using the abundant lignin in nature and the lignin obtained through paper making process, a new type of coated slow-release compound fertilizer was prepared by drum coating method and the law of nutrient of fertilizer was explored through the hydrostatic experiment of different temperature and pH Strawberry field trials explored the actual use of fertilizer. The results showed that the application of industrial lignin coated composite fertilizer, the initial nutrient release rate was 14.58%, 28d the total nutrient release rate of 58.12%, to meet the national standard (GBT23348-2009) requirements, and can significantly increase the yield of strawberries , With good development prospects.
