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

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%.
