Method for improving survival rate of jujube hardwood cutting

Abstract

The invention discloses a method for improving the survival rate of jujube hardwood cutting. The method comprises the steps of scion selection, cutting spike time, cutting spike method, cutting, postmanagement and the like. The method adopts and optimizes hardwood cutting for the characteristics of jujube trees, uses winter pruned branches as scions, easily takes the scions, is convenient to operate, can make full use of the useless pruned branches, can operate in advance during the winter leisure time according to the number of the branches, optimizes the distribution of artificial labor, isscientific and reasonable in cutting scions, uses wet sand preservation, liquid immersion and the like to maintain the vigour of the scions and prevent diseases, can greatly increase the survival rate of cutting, and promotes the growth of seedlings in the later stage.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for improving the survival rate of jujube hardwood cuttings. Background technique [0002] The jujube tree has been cultivated in China for more than 4,000 years, and its fruit is still one of the main fruits in northern China. Dates are eaten at the table as fresh fruit, dried, cooked, stewed and baked. Old production areas such as Shandong, Hebei, Shanxi, Shaanxi and Henan provinces have developed rapidly, and new areas such as Xinjiang, Gansu, and Ningxia have also developed rapidly. Because of their unique climatic conditions, they are conducive to the growth and development of jujube trees, and the quality of jujube fruit produced First-class, the development area is growing rapidly. my country is the origin of jujube, and jujube is also one of the main local tree species in Fuyang. Jujube is a plant belonging to Rhamnaceae and Jujube, a small tree with a height...

Problems solved by technology

[0003] Traditional jujube breeding methods generally include: grafting, branching, root cuttings, etc. Among them, the grafting and breeding cycle is long, and the phenomenon of large and small feet is prone to appear in the later stage of the seedlings, and rootstocks are easy to germinate tillers; root cuttings and branch breeding are time-consuming and laborious, and are not easy to produce in batches. The number of seedlings obtained is limited; these have limited the large-scale breeding and planting of jujube trees, greatly affecting the yield, increasing labor costs and reducing planting benefits
