研究不同密度和施肥量对玉米品种龙单59产量的影响，结果表明：在相同的栽培密度条件下，随着密度、施肥量的增加，龙单59的农艺性状得到改变，产量的变化有不同的差异，以施肥量磷酸二胺300 kg/hm2、尿素300 kg/hm2、氯化钾100 kg/hm2时，公顷保苗在76923株时，产量最高，达到12561.5 kg/hm2。

Effects of different density and fertilizing amount on the yield of maize varieties Longdan 59 had been studied . The results showed that the agronomic characters and yield of Longdan 59 had been improved with the increase of fertilizing amount and density under the same planting density .The change of production are different .Moreover ,the highest yield is up to 12 561.5 kg/hm2 on the condition of (NH4 )H2 PO4 、CO(NH2 )2 and KCl were 300 ,300 and 100 kg/hm2 and HA seedlings of 76 923 strains .
