高标准银杏采叶园高产优质技术研究

Study on the Techniques of the Ginkgo Leaf picking Garden with High yield and Good-quality

从种子播种建园，到叶片烘干流水线的建成，系统地研究了高标准银杏采叶园产业化生产的各个关键技术环节。通过综合技术的贯彻实施，项目区内，３ａ平均采叶产量比对照增产４０％ ，叶内脂和黄酮绝对含量比对照提高４９．９３％ 。

Ginkgo is a sort of tree with many functions and characteristics in China.The output of Ginkgo leaf and fruit in China accounted for about 65% of total output in the world.Ginkgo had been competitively developed for medicine,food,beverage and health products because its leaf and fruit had miraculous effect on preventing and curing cardiovascular diseases.By studying and popularizing the Ginkgo leaf picking garden with special purpose,the shortcoming of low benefits in its early cultivation was overcome.Now the Ginkgo leaf picking garden has become leading direction for Ginkgo cultivation.This experiment studied systematically key techniques of industrial production for high criterion Ginkgo leaf picking garden from seeding and establishing garden till the foundation of assembly line for leaf drying.By applying multiple techniques,the average leaf output was raised 40%,and the content of ginkgolide and progesterone in leaf was enhanced 49.93%.
