Broussonetia papyrifera seedling culture method

Abstract

The invention relates to a seedling culture method, in particular to a broussonetia papyrifera seedling culture method. The method comprises the following steps: (1) selection of cutting woods; (2) treatment of cutting slips; (3) preparation of a foundation bed; (4) cuttage; and (5) cuttage post-management. By the steps of selection of cutting woods, treatment of cutting slips, preparation of a foundation bed, cuttage and cuttage post-management, a scientific and reasonable planting management mode is formed, so that rooting of branches can be effectively promoted, robust development of roots is facilitated, and growth of branches and roots is promoted; nutrition can be absorbed in a rooting process, so that the content of endogenous hormones in plants and the activity of important enzymes can be adjusted and controlled; and the metabolic intensity of the plants is adjusted, the survival rate is high, the pest and disease damage is low, and the growth condition of the root system is good.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for cultivating hybrid tree seedlings. Background technique [0002] Hybrid mulberry tree is a high-quality tree species that can be planted in most parts of China after ten years of painstaking research and demonstration verification by the scientific and technological personnel of the Chinese Academy of Sciences. It adopts modern agricultural breeding technology, through space-borne breeding, hybrid breeding and other means to breed the Chinese tree species Branch No. 1, No. 2 and No. 3 hybrid mulberry tree species. [0003] Hybrid mulberry is a kind of economic crop for forestry, papermaking, and green feed development. Its leaves are a high-quality livestock and poultry feed resource, and its bark and wooden poles are raw materials for pulp and textile fibers. At present, hybrid mulberry has been Most provinces in the country promote planting, but there is no large-...

Problems solved by technology

[0003] Hybrid mulberry is a kind of economic crop for forestry, papermaking, and green feed development. Its leaves are a high-quality livestock and poultry feed resource, and its bark and wooden poles are raw materials for pulp and textile fibers. At present, hybrid mulberry has been Most provinces in the country promote planting, but there is no large-scale and industrialized planting. The main reason is that hybrid mulberry trees will not bloom and bear fruit. Hardwood cuttings are mostly used for breeding seedlings. Cutting propagation is carried out between Jingzhe and Qingming. When the hard branches germinate, the nutrients in the branches will gradually lose, the survival rate cannot be guaranteed, and the seedlings are greatly affected by the climate and environment. The seedling period lasts for one year, and the later management costs Higher, and due to unreasonable cutting methods and lack of scientific management, the slow seedling period is longer, the survival rate of seedlings is low, and a large-scale seedling cultivation system cannot be formed
