摘要
为了研制吉林省玉米带春玉米专用肥配方,以春玉米养分资源管理理论为依据,通过分析吉林省中部地区"3414"田间肥料试验结果、统计农户调查数据、整理相关文献,综合确定出吉林省玉米带春玉米氮磷钾肥的总体施用量分别为200kg/hm2、76kg/hm2和68kg/hm2,其中氮肥基肥(苗期到10叶期前)用量为52kg/hm2;结合当前农户在玉米上施用底肥习惯,确定玉米专用肥的用量为400kg/hm2,N-P2O5-K2O配比为13-19-17。
For developing a formulation of special fertilizer for spring maize in corn belt of Jilin, the study has used Spring Maize nutrient resources management theory, though to analyze ＂3414＂ fertilizer test in central Jilin, Statistics farmer＇ s investigations, reference literature and combine the base fertilizer application in corn which Agricultural workers present used. The results shows that the dose of fertilizer NPK application in Jilin is 200 kg/hm2, 76 kg/hm2 and 68 kg/hm2,amount of base fertilizer is 52 kg/hm2, Corn Fertilizer dosage is 400 kg/ the ratio of N-P2O5-K2O is 13-19-17 .
