Abstract: In the present paper, the fertilizing effects of different sludge organic fertilizers on the cultivation of Narcissus tazetta var. chinensis were probed into based on field trials. Experiments showed that the right amount of sludge organic fertilizer could promote vegetative growth of Narcissus tazetta var. chinensis, increase its chlorophyll content, enlarge the diameter of main bulb, and finally enhance its sale-rating and marketing value. Among all the prescriptions applied, Prescription III (2250kg/hm2 sludge organic fertilizer + 750kg/hm2 calcium superphosphate + 750kg/hm2 composite fertilizer) and Prescription IV (3000 kg/hm2 sludge organic fertilizer + 750kg/hm2 calcium superphosphate + 750kg/hm2 composite fertilizer) were the most effective. Sludge organic fertilizer could be used as a good soil conditioner and farmland fertilizer.
