摘　　要：以磷酸一铵(MAP)作对照,研究两种形态的聚磷酸铵(液体型简称APPY,固体型简称APPG)在砖红壤上作为种肥对玉米苗期生长的影响。通过盆栽试验,比较每粒种子P_2O_5施用量为1 g时,不同施用距离的肥效。结果表明,播种40 d后,3种磷肥不同施用位置的肥效存在显著差异,株高、茎粗、干物质累积及氮磷吸收量均在施用距离为4 cm时出现峰值,肥效最佳,植株对氮磷的吸收量最大。表明在试验条件下,3种试验磷肥施用位置距离种子4 cm时肥效最好。APPY、APPG和MAP之间没有显著的肥效差异。The effects of two forms of ammonium polyphosphates（the liquid abbreviated as APPY,the solidabbreviated as APPG） as seed placed fertilizers on the maize seedling growth on lateric red soil are studiedcompared with monoammonium phosphate（MAP）. With the dosage of 1 g P_2O_5 per seed, the effects of 5 placement distances from seed are compared in pot experiments. The results show that, after 40 days＇ seedlinggrowth, there is significant difference of plant height, stalk stem diameter, dry weight of root and above groundpart, N and P uptake among 5 placement distances for three phosphates. The distance of 4 cm shows the peakvalues of above parameters. Under the situation of this experiment, the three phosphates show the maximumeffects for seedling growth at the placement of fertilizers far from seeds 4 cm. There is no significant differenceof growth effect among APPY, APPG and MAP.
