Substrate suitable for simple direct seeding seedling cultivation of sedum plumbizincicola and direct seeding seedling cultivation method

Abstract

The invention provides a substrate suitable for simple direct seeding seedling cultivation of sedum plumbizincicola and a direct seeding seedling cultivation method, wherein a formula of the substratecomprises cow dung type earthworm manure, sawdust and turf in a volume ratio of 3: 4: 2; and the direct seeding seedling cultivation method comprises the following steps of: treating stem segments ofthe sedum plumbizincicola by using a medicament, throwing and directly seeding the stem segments on a seedling cultivation substrate, then spraying the medicament to promote rapid rooting and inducegeneration of secondary buds, and pruning a large amount of the secondary buds to carry out the simple direct seeding seedling cultivation. The substrate suitable for the simple direct seeding seedling cultivation of the sedum plumbizincicola and the direct seeding seedling cultivation method have the advantages that sawmill waste is utilized, and the sawmill waste has the advantages of low price,light texture and high porosity, can effectively increase air permeability of the substrate, reduce density of the substrate, and is beneficial to germination and growth of a root system of direct seeding stem sections; and meanwhile, benign biomass energy circulation is achieved, and cost of the substrate for the sedum plumbizincicola seedling cultivation is reduced. By the adoption of the substrate suitable for the simple direct seeding seedling cultivation of the sedum plumbizincicola and the direct seeding seedling cultivation method, a throwing direct seeding seedling cultivation mode iscombined with a special seedling cultivation substrate, so that cost of the sedum plumbizincicola seedling cultivation is effectively reduced, seedling cultivation efficiency is improved, and a powerful guarantee is provided for an environmental restoration application of the sedum plumbizincicola.

Description

technical field [0001] The invention relates to the technical field of sedum plant planting, in particular to a substrate suitable for simplified live seedling cultivation of Sedum sedum with ore, a method for preparing the substrate and a method for direct seedling cultivation of sedum with ore. Background technique [0002] Sedum with ore is a perennial succulent herbaceous plant of the Sedum family. It likes to be born in areas rich in heavy metals, and it has a strong ability to enrich heavy metal cadmium in soil. It has the advantages of fast growth, high enrichment coefficient, low repair cost, no secondary pollution and strong sustainability, so it has good potential for heavy metal-contaminated land remediation, and is often used in the remediation of heavy metal-contaminated land. application prospects. [0003] In view of the broad application prospects of Sedum sedum with ore, the demand for its seedlings has shown explosive growth. Sedum sedum has few seeds, sl...
