生物固氮菌肥施用于大棚菜地的南瓜上,在只施有机肥不施含氮化肥条件下,表现为促进南瓜早期生长,提早开花,增加结瓜数和产量;而在施有机肥基础上施用含氮化肥条件下,则表现为早期生长缓慢,开花期推迟,结瓜数减少,但瓜型较大,单瓜重最高。

Bio-nitrogen-fixing bacterium fertilizer was applied to the pumpkin in greenhouse vegetable field. Under the condition of applying only organic manure without nitrogenous fertilizer, the performance of early growth of pumpkin, early flowering and increasing the number of melon and yield were observed. On the basis of organic manure Under the conditions of applying nitrogenous fertilizer, the early growth was slow, the flowering period was delayed and the number of melon seeds was reduced, but the melon type was larger and the weight of single melon was the highest.
