| Abstract: | Using 150 and 225 kg/hm2 of P and K fertilizers as basal fertilizer in the West Orchard village of Lanzhou,field experiments were conducted to study the effects of different nitrogen fertilizer levels(0,75,150 and 225 kg/hm2) on the cumulated dynamics of bulb biomass and nutrition,fertilizer use efficiency(NFE) in rainfed land Lanzhou lily(Lilium davidii) in order to explore its requirement pattern for the fertilizer and provide basis for its standardization cultivation.The results showed that rational N fe... |
