Effect of soil preparation and fertilization on foliage and shoot growth of Ginkgo biloba and its medicine content

Abstract

Abstract: The study showed that the efficiency of various treatments in improving the height growth of Ginkgo biloba was organic fertilizer plus intercropping>soil preparation by blasting plus intercropping>organic fertilizer>soil preparation by blasting>intercropping,and the height growth increased by 14.5%,8.6%,5.7%,3.2% and 0,respectively.The efficiency of the treatments in improving new shoot growth was organic fertilizer plus intercropping>soil preparation by blasting plus intercropping>intercropping>organic fertilizer>soil preparation by blasting,and the new shoot growth increased by 58.1%,36.6%,33.1%,30.2% and 14.0%,respectively.Soil preparation,organic fertilization and intercropping had no different effect on the number of long shoots,but their effect on the numbers of short shoots and leaves was significantly different.The most efficient treatment in improving the medicine content was organic fertilization plus intercropping.Compared with control,the content of quercetin and rutin in Ginkgo biloba leaves increased by 420% and 220%,respectively.

Key words: Ginkgo biloba L, Soil preparation, Fertilization, Modular, Quercetin, Rutin
