Reshaping planting method for jujube trees

Abstract

The invention relates to the technical field of fruit tree planting, in particular to a reshaping planting method for jujube trees. The technical purpose is to provide a jujube tree reshaping plantingmethod which reshapes a high crown tree shape to a small crown heart shape, makes jujube trees be conveniently managed, makes jujubes be conveniently picked, improves grafting survival rate during grafting. According to the specific scheme, in mid-April of the first year, all one-layer branch groups of an original tree are pruned, one layer has about three branches, and each branch has three lateral branches; grafting is performed on one-layer main branches, central tree trunk is reserved, and all sprouts on the central trunk are removed during growing period; in late May or mid-to-late July,root suckers are removed; the growing period is in the next year, and all sprouts on the central trunk are continuously removed; branches with a good variety are grafted on the one-layer main branch,possess conditions of bearing fruit after one-year growth, and are stretched during the period between mid-January and early May; in mid-to-late April of the third year, the central trunk is sawed, then the saw bite is immediately smeared with a coating agent, the saw bite is closely sealed and enclosed, and no gaps are reserved to help healing of the saw bite.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a planting method for jujube trees. Background technique [0002] Belonging to the genus Jujube of the family Rhamnaceae, it is the largest dried fruit tree species and the seventh largest fruit tree in my country. Its fruit is a kind of homologous food for both medicine and food. Jujube fruit has a variety of biological activities, including anti-cancer, anti-oxidation, anti-inflammatory, liver protection, immune stimulation, intestinal protection, anti-anxiety, obesity prevention, and antibacterial properties. The results of the study showed that there are many beneficial components in jujube fruit, such as polysaccharides, phenolic acids, flavonoids, terpenoids, nucleosides and nucleoside bases, alkaloids, carotene, α-tocopherol, vitamin C, and volatile oil compounds. Among them, polysaccharides, flavonoids, phenolic acids, terpenoids and cyclic nucleotides are th...

Problems solved by technology

[0003] At present, the working population in rural areas is aging, and most of them are 50 to 70 years old. The previous high crown tree shape is not only inconvenient to manage, but also inconvenient to pick during the harvest season. In order to adapt to social development, it is necessary to improve the existing jujube trees. Retrofit the tree
