Seedling medium suitable for seedling growing of fast-growing forest and preparation method

Abstract

The invention discloses a seedling medium suitable for seedling growing of a fast-growing forest and a preparation method. A seedling growing medium is prepared from the following raw materials: 60 to 85 parts of sandy soil, 1 to 2.5 parts of magnesium sulfate, 15 to 20 parts of mature cow dung, 1 to 1.5 parts of a water-absorption water retaining agent, 10 to 20 parts of carbonized rice husk, 5 to 8 parts of pulmae bark fiber, 0.5 to 1 part of calcium magnesium phosphate fertilizer, 0.01 to 0.1 part of pimelic acid, 0.1 to 1 part of maleic acid, 1.5 to 2 parts of nitrogen phosphorus potassium compound fertilizer, 0.5 to 1 part of ammonium sulfate, 2 to 3 parts of monoammonium phosphate, 0.05 to 0.1 part of boric acid, 1 to 2 parts of polyaspartic acid, 0.6 to 0.8 part of glucosamine oligosaccharide, 2 to 5 parts of a plant disease protective agent and 0.6 to 1.2 part of activation resistant bacteria. The seedling growing medium disclosed by the invention has the functions of sufficient fertilizer efficiency, nutritional slow release, disease and stress resistance, comprehensive nutrition, strong pertinence and the like, and the germination rate and the emergency rate of seeds are increased; meanwhile, the function of promoting the growth is obtained, and the forest production period is shortened.

Description

technical field [0001] The invention relates to the field of plant seedling cultivation, in particular to a seedling substrate suitable for fast-growing forest seedling cultivation and a preparation method thereof. Background technique [0002] With the rapid development of my country's protected plant industry, plant seedling cultivation is gradually moving towards scientific, intensive, commercial and factory seedling cultivation, changing from the traditional individual form, reducing risks and links in plant planting, and greatly improving plant planting technology and industrialization process. Therefore, the planting requirements for facility plants are higher, the growth is faster, the demand for seedlings is greater, and the requirements for seedling quality are stricter. Therefore, industrialized soilless seedling cultivation, which is an important part of plant seedling industrialization, has become a symbol of agricultural high-tech. [0003] Seedling substrates ...
