| 摘 要： | 在密度为57000株/hm~2的春播条件下对沈甜6号玉米品种进行5个施肥量试验.结果表明,在施用N 187.5 kg/hm~2、P_2O_5 75.0 kg/hm~2,K_2O 97.5 kg/hm~2时产量最高,可产鲜穗13437.0 kg/hm~2,叶面积指数达到2.78,品质和各项生理指标处于较高水平.当施肥量超过N 225.0 kg/hm~2 P_2O_5 90.0 kg/hm~2、K_2O 117.0 kg/hm~2时产量下降,茎秆含糖量和叶面积指数下降.

| Abstract: | In the 57000 plant/ha spring sowing condition, the experiment of fertilizer on sweet corn Shentian No.6 were conducted.The results showed that the best fertilization of maximum yield was N 187.5 kg/ha, P_2O_5 75.0 kg/ha, K_2O 97.5 kg/ha, the fresh ear yield of sweet corn was 13 437.0 kg/ha and leaf area index of sweet corn was 2.78, the quality and each physiologic characteristic were in good condition.Over this amount of fertilization could restrain the improvement of fresh ear yield, Sugar content in sweet corn and leaf area index were both down. |
