A kind of thin shell hickory seedling raising substrate and its preparation method and application

Abstract

The invention discloses a Carya illinoinensis Koch seedling raising substrate, a preparation method and application thereof. The substrate includes turfy soil, perlite, loess, and a water diluted nitrogen fertilizer, and the mass percent of water in the substrate is maintained at 40-80% of the total mass of the substrate. The preparation method includes: mixing the turfy soil, the perlite and the loess uniformly, adding a cake fertilizer and urea, and mixing the materials evenly; further adding carbendazim or a potassium permanganate solution; mixing the materials and then conducting film mulching. Directed at Carya illinoinensis Koch, the invention puts forward a full set culture system of small container seedling raising, the substrate has simple formula components, the preparation is convenient, and the cost is low, and a certain amount of a slow-release fertilizer is added to provide nutrients for later seedling growth. Practices prove that by employing the substrate for culture, the seedling height and base diameter increment are both higher than those of a control group, and the seedling transplanting survival rate is also greatly improved. In addition, Carya illinoinensis Koch is a deep-rooted tree species, the main root is flourishing and grows rapidly, and the size of the seedling raising container can meet annual Carya illinoinensis Koch seedling root growth.

Description

technical field [0001] The invention relates to the field of forestry planting, in particular to a thin-shell pecan seedling-raising substrate, a preparation method and application thereof. Background technique [0002] The scientific name for thin-shelled pecans is American hickory ( Carya illinoinensis Koch), also known as long hickory, belongs to Juglandaceae Hickory, is an ecological and economical tree species integrating high-grade dried fruit, landscaping and high-grade wood. American pecans have 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 seedling breeding technology has not been fundamentally broken through. Large-scale production has severely limited the industrialization of the production of pecans with thin shells. [0003] At present, most of the cultivation of American hickory seedlings in China adopts the traditional field sowing seedling raisin...

Problems solved by technology

In recent years, my country's container seedling cultivation has a tendency to expand, but it is still in the preliminary stage of scientific production in general, and there is a lack of research on container types, substrate formulations, and container seedling cultivation techniques.
