A method for manufacturing a seedbed

Abstract

The invention discloses a preparation method of a novel seedling bed. The preparation method comprises the following steps: preparing a mixed raw material from the following raw materials in parts by weight: 25-35 parts of ferrotitanium stone, 35-45 parts of basalt, 5-8 parts of limestone, 3-5 parts of slag, 20-30 parts of coke and 3-5 parts of auxiliary materials; feeding the mixed raw material to a cupola furnace, fusing into magma, forming fibers, collecting cotton, and laying cotton; pressing on a three-dimensional cotton presser; and solidifying and trimming, so as to prepare the novel seedling bed. The novel seedling bed prepared by adopting the method has black to black brown color similar to the color of soil, and has a good mechanical property.

Description

technical field [0001] The invention relates to the field of agricultural materials, in particular to a method for manufacturing a seedling bed. Background technique [0002] Seedling beds used in plant breeding places such as farm nurseries generally use materials such as perlite and vermiculite as substrates. The mechanical properties and integrity of these substrates are not good, especially for three-dimensional cultivation. [0003] Rock wool is currently recognized as a very ideal substrate for soilless cultivation. But the existing rock wool material has a very important shortcoming, that is, the material strength is not enough, especially when it is used as the base material of the three-dimensional green wall, it is easy to peel off. [0004] One of the solutions to improve the peel strength of rock wool materials is to use stronger adhesives, but there will be environmental problems and the effect is not ideal. Another way is to pleat the layers of rock wool duri...

Utility model patent CN201220326750 discloses a rock wool setting system with wrinkling function, but it does not disclose details of how to achieve wrinkling

Chinese patent application 201010512495.8 discloses a rock wool pleating machine, which realizes the pleating of rock wool through the speed difference of multiple sets of upper and lower pressure rollers. The products obtained by this pleating method make each rock wool layer wrinkle. Wrinkles produce component force in the thickness direction, which is beneficial to improve the peel strength of rock wool products, but according to the product principle, it can not establish a connection between layers, so the effect on improving the peel strength is limited, and the actual sales in the market The product also confirms this

Another disadvantage is that the undulating folds in the rock wool product actually increase the tensile allowance of the rock wool layer in the longitudinal direction, giving the rock wool product more elasticity in the longitudinal and thickness directions. , this property is often not desirable
