Studies on Hardening and Transplanting Techniques of Tube-Seedlings of Chinese Date Tree,Ziziphus jujuba

This paper deals with the hardening and transplanging techniques of Chinese date tree tube seedlings, and summarizes the technological process of hardening and transplanting the seedlings.Meanwhile the authors change the conventional ringent hardening into closed hardening.The test plants grow well by the overwintering tests, and the resistance of the plants increases.So the techniques simplifies the transplant process, improves the planting survival rate, and the survival rate makes up over 90%.
