(1) The survival rate is high. Why is it that the survival rate in autumn is high? Everyone knows that no matter what kind of seedlings are planted, it takes a certain time from the winter jujube seedlings to be transplanted from the nursery to the destination. During this time, the moisture in the winter jujube seedlings will be due to the temperature and humidity. There are different degrees of loss, the spring temperature is higher, the air is dry, the water loss of the seedlings is large, thus reducing the survival rate, while the autumn temperature is lower, and the air humidity is large, the water loss of the seedlings is reduced, the winter jujube seedlings The survival rate will also be greatly improved. (2) Early results: After the winter jujube seedlings are transplanted in the autumn, in the new soil and climate, after the dormancy adaptation in autumn and winter, the winter jujube seedlings planted in the spring of the next year will grow 2-3 months earlier than the spring, so the autumn The results of planting winter jujube seedlings are early. (3) No seedlings: The back seedlings mentioned here refer to the winter jujube seedlings planted in the spring, after the buds are emitted for a while, and the buds are sent together with the saplings that the trees slowly wither. The reason for returning seedlings is mainly due to the high temperature in spring, the germination of winter jujube seedlings is relatively fast, the fast growing leaf buds consume a lot of water and nutrients in the tree, while the spring is relatively dry, the air is dry, and the water and nutrient supply of the tree is insufficient. Caused the occurrence of back to the seedlings. The winter jujube seedlings planted in autumn avoid the occurrence of back seedlings. Therefore, it is concluded that the winter jujube seedlings are most suitable for planting in autumn.
