摘要
Abstract
With the robust 3 - year - old Ginkgo biloba as material, the content variation of chlorophyll a, b and water in leaves were studied under the foliage application of different fertilizer formulas. The results showed that foliage dressing could increase the chlorophyll a content and bring the second peak forward for one month compared to the check, but could not change its dynamics in growing period. The chlorophyll b content in leaves of the foliage dressing treatments was more than that of the check from May to September, and even in October, that of PF2 and PF4 treatments was still more. Foliage dressing could increase the water content of leaves at a certain degree, which was not significant. The comprehensive analysis results showed that the PF4 treatment with foliage application of 0. 5% urea and 0. 5% monopotassium phosphate had better effect and could enhance the ornamental value of Ginkgo biloba leaves in summer and autumn.关键词
