Seedling-raising substrate and processing method thereof

Abstract

The present invention discloses a seedling-raising substrate. The seedling-raising substrate comprises the following raw materials in volume percentages: 30% of moss or herbaceous peat, 40% of coconutcoir with low salt content, 10% of perlite, 10% of vermiculite, 10% of rice husk ash and a fertilizer with a low nitrogen, medium phosphorus and high potassium structure at a concentration of 1.2 Kg/m<3>. The coconut coir with low salt content, raw ore moss or herbaceous peat, vermiculite, perlite, etc. are used, according to water retention and breathability characteristics of the materials, anappropriate ratio is adjusted to keep a stable gap structure and adaptation, fibers and particle structures of the coconut coir with low salt content well slow release porosity of the moss or herbaceous peat, so that overall porosity of the product is 70% or more. Seedlings raised by using the substrate have a root system in a net structure, are not obvious in main root system, but are very prosperous in fibrous root system, can quickly return to green and recover after being transplanted, and are improved in survival rate. The substrate-raised seedlings are not large in leaf blades and not high in plant height, the root system and stems are firstly raised, foundation is laid, although the seedlings are 2-5 cm shorter than that raised by common technique and smaller in the leaf blades, theplants are rapider in recovery and easier to survive after seedling transplanting.

Description

technical field [0001] The invention relates to the technical field of seedling raising, in particular to a seedling raising substrate and a processing method thereof. Background technique [0002] At present, the common seedling substrate products in the market are all made of pure moss or herbal peat (imported moss or herbal peat or domestic peat) mixed with a certain proportion of perlite or vermiculite. These products are marked and Stable ratio; some users purchase a single raw material by themselves, and roughly mix it according to the weather and the amount of material; there are also some low-end products that are fermented with straw, distiller's grains, vinegar grains, wood chaff, etc., and mixed in a certain proportion Perlite, there is also direct use of pure low-salt coconut peat. [0003] The above-mentioned seedling-raising substrate products only pursue long-term fertility in terms of physical and chemical properties, and do not topdress in the later stage. ...
