Embodiment Construction

[0020] The invention discloses a preparation method of a seedling-raising substrate based on solid waste. In the method, solid waste is used as a seedling-raising substrate material. The solid waste is a mixture of vermicompost, sawdust and slag. The pH value of the seedling-raising substrate is 7.5, and the EC value is It is 1298μS / cm.

[0021] Its preparation method is as follows:

[0022] For sawdust, choose pure log processing products, and do not choose artificially pressed board processing products, because artificially pressed boards usually contain chemical substances such as binders. Sawdust is a broad-leaved forest tree with a moisture content of 1.8-2.0%, and its alkali-hydrolyzable nitrogen, available phosphorus, and available potassium contents are 20-25, 40-45, and 50-55 mg / kg respectively; its pH value is 5.9-6.1 , EC value is 200-220μS / cm. The sawdust is crushed and passed through a 1mm sieve, and the under-sieve is powdery sawdust, which is set aside.

Abstract

Disclosed is a preparation method of a seedling matrix based on solid waste. The preparation method involves matrix material determination, preparation step determination and preparation proportion determination. According to the method, the solid waste is used as the material of the seedling matrix, and the solid waste is selected from wormcast and a mixture of saw dust and slag. The preparation method comprises the steps that after the saw dust and the slag are smashed respectively, the saw dust and the slag are sieved, powder-shaped saw dust and powder-shaped slag are obtained, and the powder-shaped saw dust and the powder-shaped slag are mixed according to the volume ratio of 1:1 to obtain the mixture of the saw dust and the slag; the wormcast is sieved to obtain wormcast fine powder; the mixture of the saw dust and the slag is mixed with the wormcast fine powder according to the weight ratio of 1:3 to obtain the material of the seedling matrix. According to the preparation method, the solid waste of the slag, the saw dust and the wormcast replaces the non-renewable resources such as turf, vermiculite and perlite to be used as the basic material for preparing the seedling matrix, and therefore the seedling cost is greatly lowered. The material of the seedling matrix realizes recycling of the solid waste while improving seedling stress resistance and cultivating strong seedlings.

Description

technical field [0001] The invention relates to a seedling-raising substrate, in particular to a solid waste-based seedling-raising substrate preparation method based on solid waste. Background technique [0002] Seedling cultivation is a necessary and very important link in various facility cultivation, and the seedling cultivation substrate is constantly improving and perfecting with the increasing consumption of resources. Commonly used seedling substrates are peat, vermiculite, perlite and so on. Peat has a small bulk density, good water absorption and air permeability, and an organic matter content of more than 30%. It is widely used as one of the substrate materials for seedling cultivation. However, its pH value is generally 5.5-6.5, so it is often mixed with sand, vermiculite, perlite, slag, etc. in production. [0003] The distribution of peat in my country is concentrated, and about 85% of the resources are distributed in the Zoige Plateau, the Yunnan-Guizhou Pl...
