Soilless cultivation substrate formula suitable for orchid plant and dendrobium officinale cultivation and production method of soilless cultivation substrate formula

Abstract

The present invention discloses a soilless cultivation substrate formula suitable for water plants and production method of the soilless cultivation substrate formula. The production method comprises the steps of weighing mixture of mixed polyhydroxy ethers and plasticizer dibutyl phthalate and adding the mixture into a high pressure reaction vessel, then adding natural adhesive mixture and catalyst, stirring, introducing inert gas for protection, finally adding adsorbent, fully stirring, discharging, and preparing adhesive for standby application. The production method also comprises the steps of adding decomposed straw, peat, coconut tree skin, cocoanut shells, branches and leaves in the moist state into the adhesive, stirring uniformly with high speed then keeping stationary, then adding self-prepared adhesive and stirring, pouring the adhesive into a die for molding, and finally demolding. According to the soilless cultivation substrate formula, polyethylene glycol 1000, polypropylene glycol 400 and polymer polyol in a ratio of 8:2.5:0.5 are selected, and therefore the obtained substrate can be suitable for orchid plant and dendrobium officinale growth.

Description

technical field [0001] The invention relates to a nutrient carrier, more specifically, it relates to a soilless culture matrix formula suitable for the cultivation of orchid plants and dendrobium officinale and a production method thereof. 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 applicati...

AI Technical Summary

Problems solved by technology

[0004] Orchids have higher requirements on the growth environment, so the price of orchids is much higher than that of ordinary flowers, including not only various orchids but also precious medicinal materials such as Dendrobium candidum. Substrate, difficult to adapt to the growth needs of orchids

[0005] At present, the substrates for orchid and Dendrobium officinale seedlings are good air permeability substrates, such as: sphagnum moss, but sphagnum moss is a non-renewable resource, and the mining of sphagnum moss is irreversible to the damage to the environment. At present, the country prohibits the mining of sphagnum moss to accumulate resources
