Yellow willow is a common plant on the sand dunes in eastern Inner Mongolia and western Liaoning. It is a sand-fixing tree species.
Reproduction method:
Collection and storage of seed strips: Seed strips should be 1-2 year old yellow or red-yellow flat stubble with vigorous vigor, strong and substantial. The picking time is generally at the end of autumn and early winter after the trees have fallen leaves or before the sap flows in early spring, that is, they are cut from the parent tree area during the dormant period of the tree. At this time, the branches contain more nutrients, the cutting survival rate is high, and the growth is vigorous. The collected seed strips will be stored in the kiln for winter storage. The seed strips should be stored in a cool, moist, and well-drained place. Dig a trench 80-100 cm deep. The width and length are determined by the number of seed strips. Bundle 50-100 seed strips into a bundle, put them flat in the ditch, fill with a layer of soil and bury them tightly, fill 10-15 cm of soil on each layer of seed strips, and put them in the second and third layers in turn The last layer is covered with soil 30-40 cm.
