摘要
采用水溶液聚合法,以N,N′-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,使胶磷矿、淀粉与丙烯酸盐共聚交联,制备了一种兼具保水性的含磷缓释肥包膜材料并应用于包衣尿素缓释肥。磷矿质量分数为14%时,材料在去离子水、自来水中的吸水率分别为560 g/g、254 g/g,包衣尿素的缓释周期为65 d,符合GB/T23348-2009规定的缓释要求。
Five field experiments were designed, which were respectively as follows: 25% biogas residue with 75% compound fertilizer, 50% biogas residue with 50% compound fertilizer, 75% biogas residue with 25% compound fertilizer, 100% biogas residue and regular fertilizing (100% compound fertilizer). By field experiment, the effects of different proportions of biogas residue on the growth and quality of tobacco were studied. The results showed that using 75% biogas residue with 25% compound fertilizer was helpful to promote the growth of tobacco, increase its quantity and improve its quality.
