摘　　要：为研究含壳聚糖氨基酸肥料与悬浮剂混合使用下对悬浮剂的影响,以吡唑醚菌酯、戊唑醇、噻呋酰胺3种悬浮剂的悬浮率作为对比,通过调整壳聚糖的含量、pH、与氨基酸中量元素的复配稳定性,测定与吡唑醚菌酯、戊唑醇、噻呋酰胺3种悬浮剂混合后的悬浮率。结果得出:与吡唑醚菌酯、戊唑醇、噻呋酰胺悬浮剂混合使用时,氨基酸中量元素肥料、壳聚糖的含量均会影响悬浮剂的悬浮率;且壳聚糖的浓度与戊唑醇和噻呋酰胺的混合使用时的悬浮率呈负线性相关关系;5%壳聚糖溶液的pH与5%壳聚糖溶液和吡唑醚菌酯、戊唑醇、噻呋酰胺悬浮率显极显著线性正相关;调整pH7.0,添加亚甲基双萘磺酸钠(NNO),5%壳聚糖的氨基酸水溶肥在0℃7d、54℃14d下稳定,且与悬浮剂在1∶1、1∶2比列下,与单独使用悬浮剂的悬浮率无差异,悬浮率也达到了99.0%以上。With SP of Pyrazoxystrobin,Tebuconazole and Tifuramide SC as controls,the effect of chitosan-containing amino acid fertilizer mixed with suspension concentrate(SC)on suspension percentage(SP)was studied.The SP of Pyrazoxystrobin,Tebuconazole and Tifuramide SC was determined by adjusting the content of chitosan,pH and the stability of compound with amino acid elements.The results showed that the content of amino acid fertilizer and chitosan could affect the SP of the suspension agent when it was mixed with Pyrazoxystrobin,Tebuconazole and Tifuramide;There was a negative linear correlation between the concentration of chitosan and the SP of Tebuconazole and Tifuramide;The pH value of 5%chitosan solution was significantly positively correlated with the SP of 5%chitosan solution,Pyrazoxystrobin,Tebuconazole and Tifuramide;The amino acid water-soluble fertilizer with 5%chitosan was stable at 0℃for 7 days and 54℃for 14 days by adjusting pH 7.0 and adding sodium NNO,and the SP of the fertilizer with 1∶1 and 1∶2 of SC had no difference from that of SC alone,and the SP was more than 99.0%.
