Soilless culture substrate formula used for vertical greening, and production method therefor

Abstract

The invention discloses a soilless culture substrate formula used for vertical greening, and a production method therefor. The production method comprises: weighing and adding a mixture of multi-hydroxyl ethers and a plasticizer, namely dibutyl phthalate into a high-pressure reaction kettle; then, adding a natural binder and a catalyst into the high-temperature reaction kettle with stirring, and introducing inert gas for shielding; finally adding an adosrbent with sufficiently and uniformly stirring, and discharging, thereby preparing a binder for later use; in the presence of an adhesive added in a wet state, uniformly stirring decomposed straws, grass carbon, coconut tree peel, coconut shells, branches and tree leaves at high speed to obtain a mixture, then, standing the mixture, adding a self-made binder into the mixture with stirring, pouring the mixture into a mould to form, and discharging the mixture out of mould. Polyethylene glycol 600 with molecular weight of 570-630, polypropylene glycol 200 with molecular weight of 180-220, and polymer polyol are matched in proportion, so that the soilless culture substrate formula can be suitable for splicing most of cellulose with different molecular weights; pores of a formed three-dimensional net-shaped structure are especially suitable for storing water molecules, so that water absorbing capacity of the whole substrate can be greatly improved, the gravity action can be overcome to certain extent, and the substrate is suitable for vertical greening.

Description

technical field [0001] The present invention relates to nutrient carrier, more specifically, it relates to a kind of soilless cultivation substrate formulation and its production method for vertical greening. Background technique [0002] Soilless cultivation uses light materials such as peat or forest leaf humus and expanded vermiculite as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, sow one seed in one compartment, and one plant in one room for seedlings. The root system of the seedlings and the substrate are intertwined with each other. nursery. [0003] At present, the Chinese patent with the application number CN200810102818.9 on the market discloses a root nutrition carrier, a preparation method and its application. Its main components are com...

Problems solved by technology

[0004] In the process of using the substrate, there is a way of vertical greening, that is, directly setting the substrate on the wall, but in the process of greening the wall of the substrate of the above invention, due to the action of gravity, the water will flow towards the ground along the direction of gravity, The water absorption capacity of the matrix will be poor under the action of gravity, and the water loss will be greater

If the ordinary substrate is used for a period of time for vertical greening, its water will accumulate at the bottom along the gravity, which will breed bacteria and produce various flying insects. This will not only fail to purify the air and improve the environment, but pollute surroundings
