摘要
以废旧的聚苯乙烯泡沫塑料为膜材料,用乙酸乙酯、乙酸乙酯和甲苯两种体系的溶剂进行溶解,制备了6种包膜肥料。从水中溶出率法和土壤淋溶法的结果看,制备的包膜肥料均显示了良好的控释性,且均以10%的包膜量为最佳。
With the waste polystyrene foamed plastic as the coated material, dissolving with two types of solvent, ethyl acetate, ethyl acetate and methylbenzene, six kinds of fertilizers were produced. The results of the water dissolving experiment and the soil leaching experiment indicated the coated fertilizers had better controlled release property. The best coated quantity was 10 percent.
