摘  要：
以籽用南瓜"银辉3号"为试材,采用田间小区试验方法,研究了不同氮磷钾配比对籽用南瓜全生育期内干物质的积累、分配和转运的影响,以促进籽用南瓜优质高产。结果表明:在南瓜全生育期内,全株的干物质积累量呈‘S’曲线变化,但不同的氮磷钾配比能显著影响籽用南瓜干物质积累的峰值。适宜的氮磷钾配比有利于提高果实干物质积累速率,增加库(果实)容量,为籽粒的形成提供物质基础,同时又可带动干物质在"源库"间的转运,促进瓜籽的干物质积累,从而提高籽用南瓜的产量和品质。

摘  要：
‘Yinhui No.3' pumpkin was used as materials,the field experiments were conducted to study the effects of different nutrients application ratio on dry matter accumulation,distribution and transportation of seed pumpkin,to boost seed pumpkin yield and quality.The results showed that dry matter of the whole plant accumulated as‘S'curve,the characteristics of dry matter accumulation in different stages was influenced by different nutrients application during the whole growing period.Appropriate application of N,P and K could promote the formation of fruit and increase the accumulation rate of dry matter in fruit,further on providing the material basis for seed formation.Appropriate application of N,P and K also improved the transportation of dry matter,yield and quality.
