Seepage-proof water-retaining agent and preparation method thereof

Abstract

The invention discloses a preparation method of a seepage-proof water-retaining agent. The preparation method comprises the following steps of preparing coconut shell powder and areca nut fruit powder; uniformly mixing the coconut shell powder with the areca nut fruit powder according to a certain volume ratio for fermentation, thus obtaining a fermentation product; uniformly mixing seaweed seeds with the fermentation product according to a certain volume ratio, thus obtaining soil water-retaining agent base stock; dividing loofah sponge into rectangular block bodies; mixing the saprophyte-containing nutritional water-retaining agent base stock with the loofah sponge according to a certain volume ratio, and then mixing and stirring by adding equal quantity of water, thus forming a gelatinous nutritional water-retaining agent second-level material; drying the soil water-retaining agent second-level material and compressing the soil water-retaining agent second-level material into a blocky material, and then cutting the blocky material into small blocky soil water-retaining agent three-level materials according to a certain specification; compressing the surface layers of the soil water-retaining agent three-level materials into activated carbon layers. The soil water-retaining agent disclosed by the invention is non-toxic and harmless, nutrients can be slowly released during a natural degradation process, and the quality and the yield of a cultivation plate can be increased to a certain degree.

Description

technical field [0001] The invention relates to the technical field of water-absorbing and moisturizing agents for environmental protection materials. More specifically, the present invention relates to an anti-seepage and water-retaining agent and a preparation method thereof. Background technique [0002] Water retaining agent (Waterretainingaget) is a chemical water-saving, high-tech drought-resistant product that has developed rapidly in recent years. It has been gradually applied to the production of flowers, seedlings and crops. The water retaining agent has the characteristics of fast absorption and slow release of water, which can reduce the surface water of the cultivation substrate and the evaporation of substrate water. That is to say, during the watering process, the water-retaining agent can store the gravitational water that cannot be continuously used by the plants, effectively increase the water holding capacity of the substrate, and then gradually release t...

Problems solved by technology

However, because its synthetic raw material comes from petroleum processing product acrylic acid, the shortage of petroleum energy and the rise in the price of acrylic acid increase the production cost of sodium polyacrylate water-retaining agent, and the promotion in soilless cultivation application is slow

Under certain conditions, the degradation of this type of water retaining agent may also produce harmful substances, which will adversely affect plant growth.
