Method of cultivating landscaping trees by wild-to-artificial cultivation of Choerospondias axillaris

Abstract

The invention relates to the technical field of natural forest protection and recovery, in particular to a method of cultivating landscaping trees by wild-to-artificial cultivation of Choerospondias axillaris. The method includes the steps of a, preparing a nursery and a cutting bed; b, selecting cuttings; c, pruning and treating the cuttings, to be specific, pruning cuttings, and treating the cuttings; d, performing cuttage; e, performing post-cuttage management, to be specific, managing temperature and humidity, applying fertilizers, removing weeds, and controlling disease and pest damage; f, transplanting saplings. The method is characterized in that the cuttings are selected from the male trees of Choerospondias axillaris, which are tall, straight from top to bottom, in leafy profusion and attractive in appearance and which grow for 8 to 10 years; the cuttings are selected from late May to early middle of June, after successive five sunny days, at 8 to 10 AM; the cuttings are treated with 70% ethyl alcohol for 20s and soaked in 0.1% mercury bichloride for 8min, shaking is performed nonstop, and the cuttings are washed five times with sterile water. The method has the advantages that the cuttings are all from male plants of Choerospondias axillaris and Genetic endowment of germplasm resources of wild Choerospondias axillaris can be better guaranteed.

Description

technical field [0001] The invention relates to the technical field of natural forest protection and restoration, in particular to a method for transforming wild wild jujube into artificially cultivated landscaping tree species. Background technique [0002] Southern jujube (ChoerosPondias axillaries (Roxb.) Burtt.et Hill), anacardiaceae (anacardiaceae) alias five-eye fruit, mountain jujube, flower heart wood, etc., is a large deciduous tree. The fruit, skin, root, core, kernel and leaves of the wild jujube all have medicinal effects. The tree body of the wild jujube is tall and straight, with numerous branches and leaves, beautiful shape, beautiful texture, light red color, tough texture, no insects, corrosion resistance It is wear-resistant and easy to process. It is the first-class wood for manufacturing vehicle and ship carriages, furniture, agricultural tools and architectural decorations. It is a pioneer tree species and landscaping tree species for afforestation. [...

Problems solved by technology

[0003] However, Suan jujube is a dioecious tree species, and it takes 8-10 years from seedling cultivation to mature first fruit. Before that, it is impossible to determine the female and male plants of wild Suan jujube.

If the female wild wild jujube is cultivated as a garden tree, the mature fruit of wild jujube will easily hurt pedestrians, and it will easily cause pedestrians to slip when the fruit falls on the street, and the labor intensity of sanitation workers will be increased, making this precious wild resource in the wild. The application in landscaping and industrial timber forests is greatly restricted

Because the fruit of Suanzao jujuba can be processed into the cake of Suanzao jujuba, in recent years, people have used grafting technology to cultivate female and male plants of Suanzao jujuba for fruit. The genetic disposition is not as good as cutting seedlings and seedlings
