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.
