施肥对卷丹百合产量和硝酸盐含量的影响

Effect of Fertilization on Yield and Nitrate Content in Lilium lancifolium Thunb

研究了施肥对卷丹百合产量及鳞茎内硝酸盐含量的影响。结果表明:施用化肥可以显著提高卷丹百合的产量,与对照比较,各施肥处理使百合增产250.2～1 084.0 kg/hm2,平衡施用NPK肥料的处理产量最高,为1 084.0 kg/hm2,纯收入最多,为6 716.9元/hm2。各处理中百合鳞茎硝酸盐含量最低的是PK处理,其次为NPK处理。

This study investigated the balance of fertilizer production, and Lilium lancifoliurn Thunb of the bulbs within the nitrate content. The results showed that the application of chemical fertilizer can significantly improve the Lilium lancifolium Thunb of the output, compared with the control, the fertilization treatments to make Lilium lancifolium Thunb yield 250.2~1 084.0 kg/hm2, a balanced application of NPK fertilizer treatment of the highest yield, in order to 1 084.0 kg/hm2, net income for the largest was 6 716. 9 RMB/hm2. The deal with the lowest nitrate content in the Lilium lancifolium Thunb bulb was PK treatment, followed by the NPK treatment.
