摘要
以盛产期双季米金槐为研究对象,考察氮磷钾肥用量对渝丘陵山区槐米的产量(包括构成因素)和品质的影响。结果表明,尿素、过磷酸钙和氯化钾施用量对槐米产量、产量构成因素和品质影响显著,施用尿素1.0~2.0 kg/株时可显著增加花枝上的圆锥花序、总状花序、花蕾数、单株产量及品质(总黄酮、芦丁、槲皮素、染料木素、山奈酚和异鼠李素的含量),过磷酸钙1.0~1.5 kg/株时也可显著增加花蕾数、单株产量和品质,氯化钾施用量处理没有表现出显著增加产量及产量构成因子的现象,但是施用氯化钾0.6~0.9 kg/株处理的各指标均优于低钾或不施钾的处理。从槐米高产和优质角度综合考虑,确定在渝丘陵山区槐米规范化生产上施尿素1.5~2.0 kg/株、过磷酸钙1.5~2.0 kg/株和氯化钾0.6~0.9 kg/株为佳。
With Sophora japonica at the flowering stage as the object,the effect of nitrogen,phosphorus and potassium fertilizers on the yield composition factors,yield and quality of Flos Sophorae Immaturus（ FSI） was studied. The results indicated that in early spring,nitrogen,phosphorus and potassium fertilizer on the amplification rate of S. japonica,FSI yield composition,yield and quality were different significantly,middle to high nitrogen（ 1. 5-2. 0 kg/plant） significantly increased the level of panicled clusters,raceme and flower bud number and yield. Phosphorus（ 1. 5-2. 0 kg/plant） could significantly increase the total buds of flower number and yield,potassium showed no significant increase in yield and yield components. Comprehensively considering yield and quality of FSI,nitrogen 1. 5-2. 0 kg/plant,phosphorus 1. 5-2. 0 kg/plant and potassium 0. 6-0. 9 kg/plant are appropriate.
