The jujube tree can be planted from the entire period of dormancy from leaf fall to germination. Production practices have shown that the survival rate of plants before and after budding in spring is the highest. Jujube seedlings are currently classified into:
Grade 1 seedlings: seedlings 1.2 to 1.5 meters or more in height, 1.2 to 1.5 centimeters in diameter or more, and more than 6 roots with a diameter of 2 mm or more and a length of 15 cm or more.
Secondary seedlings: seedling height 1.0 ~ 1.2 meters, diameter 1.0 ~ 1.2 cm, with more than 2 mm in diameter, length more than 15 cm of lateral root more than six.
Tertiary seedlings: The seedling height is 0.8-1 m, and the ground diameter is 0.8-1.0 cm. There are more than 4 lateral roots with a diameter of 2 mm or more and a length of 15 cm or more, and the roots are intact.
In production, one or two jujube seedlings should be used as far as possible, and tertiary seedlings can also be used, but the quality is poor and growth is slow.
