Dalbergia odorifera seedling culture substrate and preparation method thereof

Abstract

The invention discloses a Dalbergia odorifera seedling culture substrate. The seedling culture substrate is prepared from components in parts by weight as follows: 20-40 parts of mulberry sawdust, 10-25 parts of filtered mud, 5-10 parts of cow dung, 5-15 parts of bagasse, 1-5 parts of vermiculite, 1-10 parts of red mud and 10-20 parts of coconut bran. According to the Dalbergia odorifera seedling culture substrate, the used mulberry sawdust, eucalyptus sawdust and rice husks are organic solid waste produced during production and processing, the problem of disposal of organic solid waste is solved, the substrate is more environment-friendly, and the production cost is reduced. During preparation of the substrate, the mulberry sawdust, cow dung, and filtered mud are fermented for a period with aerobic fermentation bacteria, then the mixture is mixed with the bagasse and the coconut bran for aging, the mulberry sawdust and the cow dung are better fermented after the bagasse is added, the mixture is mixed with the red mud and the vermiculite after aging, the Dalbergia odorifera seedling culture substrate is obtained, the coconut bran is added to the substrate to enable the substrate to be breathable, the growth of Dalbergia odorifera seedlings is facilitated, and seedlings cultured with the Dalbergia odorifera seedling culture substrate are high in survival rate and grow well.

Description

technical field [0001] The invention relates to the field of substrates for cultivating plants, in particular to a substrate for raising seedlings of Dalbergia japonica and a preparation method thereof. Background technique [0002] Dalbergia Dalbergia is a leguminous plant, its scientific name is Dalbergia Dalbergia, and it is native to Xuwen, the southernmost tip of mainland China. Because of its slow growth, solid wood, and beautiful patterns, huanghuali wood, rosewood, chicken wing wood, and iron wood are also known as the four famous woods in ancient China. It has always been listed as one of the four famous trees, and is now a national second-class protected plant. Most of the existing cultivation substrates of Dalbergia Dalbergia are organic-inorganic composite substrates, or composite substrates with complex formulas and non-renewable resources as the main components, such as peat, which have a high cost of use. The mining and processing of non-renewable resources ...

AI Technical Summary

Problems solved by technology

Most of the existing cultivation substrates of Dalbergia japonica are organic-inorganic composite substrates, or composite substrates with complex formulas and non-renewable resources as the main components, such as peat, and the cost of use is relatively high

The mining and processing of non-renewable resources has caused great damage and pollution to the environment. The cost of using peat is high. Excessive mining will inevitably cause resource depletion and destroy the ecological balance.
