The invention relates to a light desulfurized plastering gypsum, an auxiliary agent and a preparation method thereof, and relates to the field of plastering gypsum. The auxiliary agent of light desulfurization plastering gypsum includes the following raw materials by weight: 3-10 weight parts of heavy calcium, 5-10 weight parts of aging stabilizer and 0.1-0.3 weight parts of anti-cracking and crystallizing agent. The additive of the present invention can effectively accelerate the aging of gypsum by adding an aging stabilizer, an anti-cracking and crystallizing agent, etc., and is formulated with other additives (light fillers, etc.) to make the unstable and uneven gypsum phase rapidly It tends to be stable and uniform, and reduces the water demand, improves the strength, and stabilizes the setting time, which prevents and avoids the risk of plastering gypsum cracking at all stages.

The invention discloses a corn stalk compound substrate suitable for soilless culture of vegetables and a preparation method thereof. The compound substrate comprises 8 volume parts of corn stalks and 2 volume parts of river sand. Various indexes of the compound substrate disclosed by the invention meet requirements on growth and development of the vegetables and reach a standard of soilless culture substrates; organic components account for about 80%, the service life reaches 2-5 years or longer, and the cost of the corn stalk compound substrate is reduced by 60-80% compared with that of conventional substrates, for example, 80% compared with that of rock wool, 75% compared with that of vermiculite, 75% compared with that of cocoanut shells, 70% compared with that of grass carbon, and 60% compared with that of perlite. The corn stalk compound substrate achieves recycling of stalks, saves natural resources, and provides an effective development outlet for protection of ecological environments.
