有机无机氮肥对金银花质量的影响

为研究有机氮肥与无机氮肥的施用对金银花质量因子的影响。以盆栽7年生金银花为试验材料,采用紫外分光光度计法测定金银花中总绿原酸和黄酮含量。结果表明:在磷钾肥充足供应下,单施有机氮肥虽对金银花千蕾质量起正效应,但对花和叶内绿原酸和黄酮的含量起负效应,而单施无机氮肥效果正好相反,只有有机氮肥和无机氮肥混合施用才不会降低金银花的质量,因此,在金银花种植中应将有机氮肥和无机氮肥结合施用。

Effects of Organic nitrogen and Inorganic Nitrogen on Quality of Honeysuckle

A pot experiment with 7-year orthodox honeysuckle as materials was conducted to study the effects of organic nitrogen and inorganic nitrogen on factors of honeysuckle quality.The results showed that,with the sufficient supply of phosphate and potassium fertilizers,application of only organic nitrogen played positive roles on 1 000-bud weight of honeysuckle,but decreased the concentration of chlorogenic acid and flavonoid in the flower and leaf.However,the opposite results were observed when inorganic nitrogen was applied.Combined application of organic and inorganic nitrogen fertilizer did not decreasee the quality of honeysuckle.So,combined application of organic nitrogen and inorganic nitrogen should be commended in the growth of honeysuckle.
