Problems solved by technology

However, although polyacrylamide itself is non-toxic and harmless, if it exceeds the control amount during use, it will have a certain impact on human health. At present, there are few reports on this aspect, and whether there are potential safety hazards remains to be seen. Validation, but at least there is a potential security risk

preparation example Construction

[0021] The preparation method of soil organic water retaining agent of the present invention comprises the following steps:

[0022] a. After mixing urea, ferrous sulfate, and cellulose according to 3-8:1-5:12, add the remaining cellulose, and mix again to obtain material A;

[0023] b. Mix fulvic acid and modified konjac flour at a ratio of 1:1, then mix with material A and the rest of modified konjac flour, granulate, and dry to obtain.

[0024] Further, as a preferred solution, in the step a, first mix urea, ferrous sulfate, and cellulose according to 5:3:12, then add the remaining amount of cellulose, and mix again to obtain material A.

Abstract

The invention relates to an organic soil water-retaining agent and a preparation method thereof, and belongs to the field of production of crops. The organic soil water-retaining agent is prepared from the following components in parts by weight: 40-60 parts of modified konjaku flour, 10-20 parts of fulvic acid, 3-8 parts of potassium hydroxide, 1-5 parts of ferrous sulfate, 3-8 parts of urea and 18-25 parts of cellulose. The organic soil water-retaining agent has a good water absorption property; after water is added, the organic soil water-retaining agent can rapidly absorb the water to be expanded; and thus the organic soil water-retaining agent has a very remarkable effect of improving the moisture content in soil. The water-retaining effect is equivalent to that of an existing water-retaining agent; and meanwhile, all the components in the organic soil water-retaining agent are environmentally friendly, and do not cause the environmental pollution problem.

Description

technical field [0001] The invention relates to a soil organic water-retaining agent and a preparation method thereof, belonging to the field of crop production. Background technique [0002] The soil water-retaining agent can quickly absorb and retain rainwater or irrigation water in the soil without seepage, thereby ensuring sufficient water in the rhizosphere and releasing it slowly for plants to use. Its unique water absorption, water storage, and water retention properties play a decisive role in improving the ecological environment and windbreak and sand fixation projects. Soil water retaining agent is widely used in land desertification control, agricultural and forestry crop planting, landscaping and other fields. [0003] The Chinese patent application with the application number 201110373992.9 discloses a soil water retaining agent, which is polymerized from the following raw materials according to the following weight ratio: 100-200 parts of hydroxyethyl acrylate...
