Before selecting cuttings, we should lay the cuttings matrix first, so that we will not lose too much nutrients because of the delay of laying the cuttings matrix.
The cutting medium of Prunus amurensis can be made of vermiculite powder, perlite and peat soil in the proportion of 2:1:1. It should be noted that the three are not directly mixed, but first spread the peat soil, and then mix the other two evenly in proportion, and then spread them on the top of the peat soil.
In addition, the requirement of cutting medium is loose and airy, suitable for the growth of plants.
The branches used for cutting are the branches between 10 and 12 cm cut from the strong mother branches of the red leaf dwarf Nanking cherry, and each branch is guaranteed to have four or five bud nodes.
After cutting the cuttings, they should be stored in a cool and humid place, or wrapped up with wet things, to avoid water loss as much as possible, so as to improve the survival rate.
Cut a 45 ° oblique incision on the top of the cuttings 2cm away from the bud node, and then soak the cuttings in NAA solution or rooting powder solution for a period of time, 30 to 60 minutes.
The cutting depth should be more than one-third and less than one-half of the cutting length, and the spacing is generally between 2.5cm and 3.5cm. After cutting, the cutting substrate should be watered.
