以黄瓜品种“驰誉A5”、“津优35”为试材,进行日光温室氮肥总量控制试验,研究目标产量为52 500kg/hm~2,磷、钾施用纯量分别为127.5、180.0kg/hm~2条件下的氮肥施用量。结果表明:纯氮用量达169kg/hm~2时黄瓜品种农艺性状、经济产量、肥料投入与收益均最佳。经验证优化得出试验区温室黄瓜最优施肥比例为N∶P_2O_5∶K_2O=11.0∶8.5∶12.0;对于生长量大、生育期较长的品种,秋延后或越冬茬栽培时需增加生长中后期的追肥次数和追肥量。
The total amount of nitrogen fertilizer in solar greenhouse was controlled by the cucumber variety “Chih-fong A5 ” and “Jinyou 35 ” with the target yield of 52 500kg / hm ~ 2 and pure phosphorus of 127.5 , 180.0kg / hm ~ 2 under the conditions of nitrogen fertilizer. The results showed that the agronomic traits, economic yield, input of fertilizer and income of cucumber varieties were best when the amount of pure nitrogen reached 169kg / hm ~ 2. The optimal fertilization ratio of greenhouse cucumber was N:P_2O_5:K_2O = 11.0:8.5:12.0 in the experimental area. The results showed that for the varieties with longer growth period and longer growth period, The number of top dressing and the amount of dressing.
