The Harvesting of Ginkgo leaves Part 4


  • Optimal tree age for leaf harvesting
  • Optimal cultivation pattern
  • Optimal harvest time

  • Preparations in harvest time
  • Harvest method

Manually pick the leaves one by one, and put them into the baskets or bags that have been prepared in advance. Once the baskets or bags are full, deliver them to the concentrated container. At set intervals, send them to the prepared drying ground to spread them for drying. Do not scatter them on the ground or stack on the field temporally. The picking should be from up to down and from inside to outside batch by batch. All leaves should be picked in twice or three times.


  • Precautions in picking operation
