Culturing method of plantlets of rare tree erythrophloeum ferdii

Abstract

The invention discloses a culturing method of plantlets of rear tree erythrophloeum ferdii. The seeds of the erythrophloeum ferdii are sown by adopting a conventional method. The method is characterized in that the mixed matrix of yellow subsoil and biogas residue is arranged on the lower layer of a seedling cultivating matrix, and pure yellow subsoil is arranged on the upper layer of the seedling cultivating matrix, biogas slurry, seaweed oil and a compound fertilizer are mixed to be used for cultivating an additional fertilizer to obtain the good and healthy plantlets of the erythrophloeum ferdii. According to the method, the fertilizer damage as the epidermises of the seedlings which are transplanted just now are tender and sensitive to the fertilizer can be effectively prevented by the cultivating matrix; when the seedlings recover to grow new roots, the biogas fertilizer on the lower layer can be conveyed upwards slowly along with water content, so that the seedlings can absorb the nutrients needed by the growth in time; the biogas slurry, the seaweed oil and the compound fertilizer are taken as the additional fertilizer to be applied in a matching manner, so that the purpose of making good for deficiency is realized, and the fertilizer efficiency is improved; and the resources of raw materials are sufficient, the cost is low, the method is simple, the operation is convenient, the nutrition content is comprehensive, the absorptivity is good, the survival rate is high, the growth of the seedlings is facilitated due to the combination of rapid release and slow release of the fertilizer effect, and the culturing method adapts to the demands of accelerating the development of the rare and endangered erythrophloeum ferdii.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a method for cultivating rare tree species gridwood seedlings. Background technique [0002] Erythrophleum fordii Oliv, also known as Azalea, Doudengfeng, and Gufenchai, belongs to the genus Erythrophleum of the family Caesalpiniaceae. It is listed in the first volume of the Red Book of Chinese Plants. One of the plants. It is naturally distributed in my country's Guangxi, Guangdong, Fujian and Taiwan provinces and regions, as well as in Vietnam and Laos. Grid wood is a precious timber species with high economic value. Its wood is odorless, has straight texture, fine and firm structure, and has been immortal for thousands of years. It is firm like iron, with a specific gravity of 0.67. It has no shrinkage and deformation after drying, so it is called iron wood. , It is resistant to corrosion and humidity, and is mainly used in the production of high-end furniture and handicr...

Problems solved by technology

However, in the existing cultivation methods of lattice wood seedlings, there are still insufficient seedling substrate fertility, or substrate fertility and uneven supply, resulting in low survival rate of seedlings, slow growth, poor economic and social benefits, and directly affect the quality of rare tree species. development of wood forestry
