(1) With the variety FuBrilliant of tulip grown by sand culture,we investigated the effect of three elemental and season of nitrogenous manuring on yield and quality of tulip bulbs and the experimental plots were as follows, NPK, (2N)PK, (3N)PK, NP(2K), NK, NP, PK and Non fertilizer.
(2) Nitrogen had much effect on yield and quality, and then potassium and phosphoric acid. Nitrogenous manurig at the beginning stage of growth and beginning stage of development of the vegetation point had good effect on growth and yield.
(3) Non nitrogen and non phosphoric acid eheked the flower bud differentiation of bulb.
