试验结果表明,4号营养液为最佳配方其N:P:K=13:10:7。
11种营养液在氮磷钾配比上有所不同(微量元素的含量和配比是相同),从而可观测出不同种营养液处理对仙客来生长势和光合作用的强弱的影响。
从试验统计数据中可以看出,4号营养液处理的仙客来植株在生长势上和各种生理指标上要高于其他营养液处理的仙客来。
并且用其处理后的仙客来花朵数多于其他营养液处理后的花朵数,有较高观赏价值。
从而得出的结论是氮、磷、钾施用量适宜、配比合理,则叶面积较大,叶片叶绿素含量较高,叶片光合作用较强,高光效持续期长,所以有利于较多的干物质积累,可形成较高的生物量。
所以我们在选择用营养浇灌仙客来时应选择Ca、K、N含量比较高的来浇灌,这样有利于光合作用。

Test results showed that the nutrient solution on the 4th best formula for the N : P : K = 13:10:7. 11 nutritious liquid NPK ratio is somewhat different (and the content of trace elements is the same ratio), so they could observe different kinds of nutrient solution on cyclamen growth potential and photosynthesis of the strength of the impact. Statistics from the test data, we can see that on the 4th of nutrition Cyclamen plants in growth potential and physiological indicators than other nutrition of cyclamen . And used his treatment, the cyclamen flowers than other nutrient solution after a few flowers, which have a higher ornamental value. Came to the conclusion that nitrogen, phosphorus and potassium dose appropriate, a reasonable ratio, the larger the leaf area, chlorophyll content, Photosynthesis strong, high-efficiency long duration, it is more conducive to the accumulation of dry matter, can form a higher biomass. Therefore, we choose to use nutrition watering cyclamen should
