摘　　要：本试验研究了不同施肥处理对黄瓜养分吸收及光合产物分配的影响。结果表明：黄瓜苗期光合产物主要分配到叶片，成株期主要分配到果实，果实干物质含量占总量的40．98％～44．99％。施用有机肥处理植株总的干物质含量均比施用化肥处理的高，尤以70％有机肥且套种三叶草处理表现最好，较其他处理增加2．53％～21．11％。黄瓜苗期根和叶当中的氮磷钾含量较高，成株期养分主要分配到果实，果实中氮磷钾之比为2．13：0．79：5．23，70％有机肥且套种三叶草处理植株各部分养份含量均处于较高水平，且成株期70％有机肥且套种三叶草处理土壤速效氮含量与其他处理相比增加7．58mg·kg^-1-31．98mg·kg^-1，速效钾含量增加了16．94mg·kg^-1-22．94mg·kg^-1，速效磷含量增加了4．18mg·kg^-1-53．03mg·kg^-1，因此从本试验结果看，施用70％的有机肥且套种三叶草是温室黄瓜有机栽培可选用的施肥方式。Effects of different fertilizer treatments on production of cucumbers were studied. The results showed that the distribution ratio of dry matter and nutrition in leaves and root was higher during the seedling, then the distribution ratio increased in fruits . The cucumbers of 70% M ＋ T can not only have more dry matter, but also can promote the soil nutrient contents, during the fruit stage, the contents of soil available nitrogen increased 7.58 ～ 31.98mg· kg^- 1, potassium increasedl6.94～22.94mg . kg - 1, phosphorus increased 4.18 ～ 53.03 mg· kg^- 1.
