Embodiment 1
[0061] Embodiment 1: a kind of using method of the soilless culture tank of Chinese yam, is characterized in that comprising the following steps:
[0062] a. Substrate preparation and disinfection: The volume ratio of peat soil, decomposed cow dung, pottery gravel powder, and decomposed sawdust in the matrix formula is 4.5:2.5:1:2; the disinfection method is: put the substrate to be disinfected on a clean, pad Spread 8cm thick on the ground with a layer of plastic film, dilute the formaldehyde solution with a concentration of 40% by 50 times, spray the diluted formaldehyde solution with a sprayer to wet this layer of substrate, then spread the second layer of substrate, and then use formaldehyde solution Spray wet until all the substrates to be sterilized are sprayed with formaldehyde solution, cover and seal them with plastic film for 1 day and night, spread out the sterilized substrates, and expose them to the sun for 2 days until there is no formaldehyde smell in the substra...
