Problems solved by technology

The yellow core soil substrate used for traditional container seedlings is relatively compact, with poor ventilation and water permeability. There are generally problems such as poor root growth and weak stress resistance of seedlings. At the same time, the substrate is too heavy, which affects planting efficiency and increases afforestation. cost, and not suitable for afforestation in dry seasons

Embodiment 1

[0023] A kind of container seedling raising light substrate of walnut catalpa, its preparation method comprises the following steps:

[0024] (1) Use a pulverizer to crush the fungus sticks into 5-7mm slag to obtain crushed fungus sticks.

[0025] (2) Add 0.5kg / m to the pulverized fungus stick crushed material -3 urea, and add an appropriate amount of water to mix; then add a compound biological starter (the mass ratio of the compound microbial agent to the ground material of the fungus stick is 1:1000), add water and stir evenly, so that the fermentation humidity is maintained at 75%- 85%, piled into a mountain bag shape, covered with a plastic film, compacted around for fermentation, turned once every 15 days, and fermented for 30 days to obtain agaric fungus stick fermentation material.

[0026] (3) The raw materials are composed of 30% peat soil, 30% perlite, and 408% agaric fungus stick fermentation material by volume percentage. After mixing the above raw materials and ...

Abstract

The invention provides a light medium for container seedling raising of Juglans mandshurica Maxim, and relates to the technical field of Juglans mandshurica Maxim planting. A preparation method of thelight medium for container seedling raising of the Juglans mandshurica Maxim comprises following steps: raw materials comprise 26%-33% by volume of peat soil, 26%-33% by volume of perlite and 35%-48%by volume of a black fungus stick fermentation material, the raw materials are mixed and stirred uniformly, then the mixture is drenched thoroughly with a potassium permanganate solution and disinfected and is spread and aired for 5-7 days after 24 h, and the light medium for container seedling raising is obtained, wherein the black fungus stick fermentation material is replaced with a sawdust fermentation material. The raw materials can be changed into wealth from waste, the medium is environmentally friendly and saves cost, the prepared medium has low mass and good breathability and water permeability and effectively promotes seedling growth, seedlings grow healthy and strong, terminal buds are full, degree of lignification is high, and seedling quality is obviously improved when the seedlings are transplanted from the nursery.

Description

technical field [0001] The invention relates to the technical field of planting of walnut catalpa, in particular to a light substrate for container seedling cultivation of walnut catalpa. Background technique [0002] Walnut catalpa (Juglans mandshurica Maxim.), also known as Juglans mandshurica Maxim., is a deciduous broad-leaved tree of the family Juglandaceae (Juglandaceae). , is a national second-level rare tree species and a third-level protected plant for China's rare and endangered tree species. It is a promising woody oil plant, and it is also a precious timber and economic tree species in Northeast China. Its material is hard and compact, has good elasticity, and is easy to process. It is an excellent military joinery and furniture material; the pulp and bark contain tannins; the seeds are rich in fat and nutritious, edible or for industrial use; the bark and leaves are medicinal It has the functions of eliminating heat, detoxification and anti-cancer, and has impo...
