摘要
试验以银杏为研究对象,采用不同浓度的氮肥、磷肥、钾肥、氮磷钾复合肥及微肥处理花芽分化期的银杏叶片,研究不同叶面肥料对银杏花芽分化期的生理影响。试验表明氮磷钾复合肥(0.5%尿素与0.5%磷酸二氢钾)对提高银杏叶片的叶绿素含量及叶片光合作用效果最好;钾肥有利于提高叶片可溶性蛋白的含量。
The experimentation took the gingko as research object, studied on physiological characteristics of gingko leaves by spraying differernt densities of foliar fertilizers of nitrogenous and phosphate, potassium, nitrogen-phosphorus-potassium compound and microelement fertilizers at flower bud idiophase. The results indicated that n-p-k compound fertilizer （0. 5%urea and 0.5% potassium dihydrogen phosphate） has the best effect in improving chlorophyll content and blade photosynthesis of the ginkgo blade. The potassium has benefit to enhance soluble protein contents.
