The first echelon of Zhandong No.2 Dongzao came out as the leader again.

"the skin is thin and the meat is crispy and the taste is sweet. This is our new Zhanhua winter jujube variety-'Zhendong 2'. Our jujube basically follows the technical guidance of experts, using more organic fertilizers, more biological and physical control, and less pesticides. Therefore, there will be the original winter jujube, in order to participate in the competition to win the grand prize. " Recently, Ding Xizhang, a jujube farmer, told reporters in Youfang Village, Gucheng Town, Zhanhua District, Binzhou City, Shandong Province. After careful inquiry, we learned that Ding Xizhang won the special prize in the Winter Jujube Competition held on September 27 by relying on the new variety "Zhandong 2" and standardized planting techniques.

Guo Qinghong, deputy director of Zhanhua winter jujube industrial office and president of Zhanhua winter jujube research institute, said Zhanhua winter jujube is a rare and valuable fresh food variety among jujube resources in China. It is famous at home and abroad for its excellent fresh food quality, strong adaptability and unique maturity. In recent years, due to continuous planting for many years, Zhanhua winter jujube has some problems, such as variety degradation, mixed lines, declining quality, low ability to resist market risk and so on. In view of this, Zhanhua successfully selected a new tetraploid variety "Zhendong 2", which is an excellent variety of Zhanhua winter jujube through the comparative test of several strains, starting with the purification of strains and breeding of excellent varieties.

Zhendong No. 2, a more excellent late-maturing fresh jujube variety selected from Zhanhua winter jujube, matured in the middle and late October. It has the characteristics of large fruit, flat and round fruit, bright fruit surface, thin and crisp skin, much juice, good taste, high sugar content, rich nutrition and so on. Moreover, "Zhendong 2" has high economic value because of its strong adaptability, cold resistance, drought resistance, salt tolerance and barren resistance.

Guo Qinghong said that compared with the traditional winter jujube, "Zhandong 2" has three outstanding characteristics: first, it is moderate in growth, weak in branching power, and easy to set fruit. Only a very small number of buds of "Zhandong 2" can be extracted into jujube head branches, unlike the traditional Zhanhua winter jujube, where each jujube stock sprouts into jujube head, thus reducing the amount of labor occupied each year due to sprouting, the moderate tree potential, concentrating nutrition and improving the fruit setting rate. Second, the ovary of jujube flower is larger, the shape of jujube fruit is beautiful, and the size is larger. "Zhandong 2" is about twice the size of ordinary winter jujube, and grows faster, with an average of more than 20 grams each, and has a beautiful appearance, while the traditional Zhanhua winter jujube has various fruit shapes, round, long oval, extremely irregular and uneven size. Third, the quality is better. "Zhandong 2" has thinner skin, more juice, more crisp and sweet taste, more rich nutrition, and the content of soluble solids is 1.3 times higher than that of common Zhanhuadong jujube.

Based on the above reasons, Zhanhua regards speeding up the promotion of the new variety "Zhendong 2" as the main starting point to promote the transformation and upgrading of winter jujube industry. relying on jujube ear picking nursery, Chinese improved varieties jujube gene bank, Chinese Bohai high-tech seedling breeding field and so on, the efficient Zhanhua winter jujube rapid propagation system Through the combination of planned close planting and green cultivation techniques, the rapid breeding and green and efficient cultivation techniques of "Zhandong 2" were explored and innovated. "Zhandong 2" early-bearing, high-yield, high-quality and efficient close-planting cultivation model and supporting technical measures were established, which laid the foundation of varieties and techniques for rapid popularization.

Since 2014, Zhanhua has stipulated that the newly built or rebuilt planting area of "Zhandong 2" will reach more than 50 mu, with a reward of 500 yuan per mu, and the improved area of "Zhandong 2" has been completed to 35000 mu.
