Abstract

The invention discloses a pecan culture substrate and a preparation method thereof, comprising edible fungus residue, loess and urea, and water in the substrate accounts for 50-60% of the total mass. The preparation method of the matrix is ​​to mix the edible fungus residue and loess with a volume ratio of 2-4:1, add 0.5% urea by mass of the total matrix, and mix evenly; then add carbendazim or potassium permanganate solution to keep the matrix in the Water accounted for 50–60% of the total mass; then the film was covered for 7–10 d. The invention proposes a complete culture system for seedlings in small containers for Pecan americana. The substrate has simple formula components, convenient preparation and low cost. A certain amount of long-acting fertilizer is added to provide nutrients for the growth of seedlings in the later stage. The growth of height and ground diameter were higher than those of the control group, and the survival rate of seedlings was also greatly improved. In addition, American pecan is a deep-rooted tree species, with well-developed taproots and rapid growth, and the size of the seedling container can meet the root growth of annual American pecan seedlings.

Description

technical field [0001] The invention relates to the field of forestry planting, in particular to an American pecan culture substrate and a preparation method thereof. Background technique [0002] American Pecans ( Carya illinoinensis Koch), also known as thin-shell hickory, long hickory, belongs to Juglandaceae Hickory, is an ecological and economical tree species integrating high-grade dried fruit, landscaping, and high-grade wood. American hickory has been introduced to China for more than 110 years, but up to now, industrialized production has not been formed. One of the main technical reasons is that the breeding technology of seedlings has not been fundamentally broken through. Large-scale production has seriously limited the industrialization of pecan production. [0003] At present, most of the cultivation of American hickory seedlings in China adopts the traditional field sowing seedling raising method (bare-rooted seedlings). Due to the deep-rooted characteristi...
