Problems solved by technology

People often fertilize and spray plants according to fixed seasons, but people cannot correctly grasp the amount and type of fertilizer and medicine needed by plants in different growth periods
Although fertilizers and medicines have been applied, the results are often unsatisfactory. Not only can the yield not be increased, but the soil will even be hardened.

Embodiment Construction

[0006] A composite moisturizing agent, the preparation method of which is as follows: mixing 20-40% water-retaining agent and water-soluble fertilizer by weight, stirring and heating at a heating temperature of 80-90°C; drying the mixture.

[0007] The water-retaining agent adopts a water-absorbing resin chemically composed of acrylamide and potassium acrylate cross-linked and copolymerized: the appearance of the water-absorbing resin: before water absorption: white powder; after water absorption: transparent colloid; the maximum water absorption ratio (weight ratio) of the raw material Deionized water: 300 ——500 times, salt water: 30—50 times; ionic characteristics: anion; PH value: 5—7 water solubility: insoluble.

[0008] Potassium dihydrogen phosphate is used as water-soluble fertilizer. Potassium dihydrogen phosphate, its appearance: white granular crystal, PH value: neutral, water solubility: soluble in water, active ingredient: boron (B) + iron (Fe) + manganese (Mn) + z...

Abstract

The invention discloses a compound humectant. A method used for manufacturing the compound humectant comprises: water retention agent with the weight ratio of 20-40% is mixed with water soluble fertilizer, and then the mixture is stirred and heated at the temperature of 80-90 DEG C; the mixture is dried. The compound humectant has the characteristics of avoiding fertilizer and pesticide from draining away and dissipating, preventing fertilizer and pesticide from polluting the environment, leading the soil to form crumb structure, improving soil, saving water source and lowering planting cost.

Description

technical field [0001] The invention relates to a compound moisturizing agent. Background technique [0002] In the past, water-retaining agents could only meet the needs of plants. It was believed that enough water was enough for plant growth. Other important conditions such as fertilizers and pesticides could meet the needs of plants only by manual application and sprinkling. No one knows that plants need different types of fertilizers and chemicals at different times from the time the seeds germinate. People often fertilize and spray plants according to fixed seasons, but people cannot correctly grasp the amount and type of fertilizers and medicines that plants need in different growth periods. Although fertilizers and medicines have been applied, the results are often unsatisfactory. Not only can the yield not be increased, but even the soil will be hardened. Contents of the invention [0003] The purpose of the present invention is to provide a kind of composite moi...
