Ginkgo timely storage quality is good

Ginkgo timely harvesting, peeling, grading and storage, not only can increase the yield of Ginkgo biloba, but also to ensure the quality of ginkgo, so that the economic benefits of Ginkgo biloba production has been greatly improved. 1. Harvest time: Beginning in late September, the ginkgo biloba outer seed coat has changed from greenish green to orange-brown or blue-brown, and it has been squeezed softly. The surface of the outer seed coat is covered with a thin layer of white fruit powder. This time is ginkgo. The harvest period is appropriate. 2. Peeling: The collected Ginkgo biloba is piled together and the thickness is not more than 30 cm. It is suitable to cover the wet grass and stack it for 2-3 days until the seed coat rots. Then you can use the foot to step or use wood. Tap to remove the outer seed coat. Because ginkgo biloba outer seed coat contains alcohol, phenol, acid and other chemical substances, it will cause people's skin itching, and even dermatitis and other allergic reactions, so during the peeling operation should try to avoid direct skin contact with ginkgo. 3. Bleaching: After removing the ginkgo seed coat, it should be immediately bleached and rinsed in bleach solution. Excessive stay will make the seed coat dull and reduce the quality of ginkgo. 4, dried: Ginkgo after bleaching can be directly on the indoor or outdoor shade dry. During the drying process, it should be turned to prevent yellowing or mildew on the seed coat. 5, storage: Select a cool room, in the ground first layer of 10 cm thick wet sand (in order to pinch can not be a group is appropriate). Spread ten centimeters thick ginkgo on top of the wet sand, and then spread 5 cm thick wet sand. This can be multi-layered, but the total height should not exceed 60 cm. Keep it moist during storage. This method can be stored for 4 to 5 months.
