- 摘要:
- 以美洲南瓜杂交种‘金辉四号’为试材，采用单因素随机区组设计，研究不同N、P、K配比对其产量的影响，以明确美洲南瓜生产中最佳N、P、K施肥配比。结果表明：在南瓜全生育期内，全株的干物质积累量变化呈先升高后稍有降低的曲线变化，不同的氮磷钾比例影响籽用南瓜干物质在不同部位中的积累量，适宜的氮磷钾配比可以增加籽用南瓜果实干物质的积累量，通过提高籽粒的饱满度和田间的坐果率达到增产效果。
- Abstract:
- The Cucurbita pepo hybrid ‘Jinhui four’ as experimental material, single factor randomized block design was used in order to determine the best ratio of N, P and K in fertilizer in production of Cucurbita pepo. The results showed that the changed trend of dry matter accumulation showed increased before slight decreased during the whole growth period of the pumpkin. The proportion of different nitrogen, phosphorus and potassium in fertilizer affects the accumulation of dry matter in different organs of pumpkin. The suitable ratio of nitrogen, phosphorus and potassium could increase the accumulation of dry matter of pumpkin fruit, and increasing the plumpness and fruit setting to increase pumping seed yield.
