Multiple-effect super absorbent resin fertilizer and manufacturing method thereof

Abstract

The invention provides a multiple-effect super absorbent resin fertilizer. In the manufacturing process, sodium hydrogen sulfite and ammonium persulfate oxidation-reduction type initiator are used as foundations, and ultraviolet initiation is used as an auxiliary means; N-N'-methylene bisacrylamide is used as a crosslinking foundation, and ethylene glycol diglycidyl ether and glycerol are used as auxiliary means; hydroxyethyl acrylate is added in the polymerized monomer, so that the colloid strength of the high molecular polymer is obviously improved; antioxidant, ultraviolet absorbent and light stabilizer are creatively introduced, thus finally manufacturing super absorbent resin having oxidation resistance, light resistance and degradation resistance; the super absorbent resin is organically combined with humic acid, microbial inoculant and an inorganic fertilizer to perform synergistic action, so that the various effective elements achieve the optimal use effect. Meanwhile, the consumption of the inorganic fertilizer is reduced, the salt content of soil is reduced, the pH value of the soil is improved, the soil environment is improved, and soil hardening is prevented, thus greatly increasing the utilization ratio of nitrogen fertilizers, phosphate fertilizers and potassium fertilizers, and achieving comprehensive effects of water saving, fertilizer saving, yield increase and outcome increase.

Description

technical field [0001] The invention relates to a multi-effect high-water-absorbing resin fertilizer and a preparation method thereof, which can be widely used in agriculture, afforestation, urban landscaping, sandy land control, environmental control projects, and soil improvement projects. Background technique [0002] my country is a country seriously short of water. There are more than 800 cities with drinking water for the urban population that are seriously short of water. There is an abnormal lack of water resources in agriculture and forestry, especially in the northwest region. The desertification is serious year by year. The natural environment Deterioration, dry climate, dry land, depletion of groundwater, decreasing rainfall year by year, increasing evaporation of land water year by year, decreasing fertilizer utilization rate year by year, land deterioration, and increasing irrigation costs year by year. Agriculture and forestry production is facing a severe test...

Problems solved by technology

Agriculture and forestry production is facing a severe test. Based on the actual situation of our country, a new type of drought-resistant and water-saving technology is especially needed, especially in the arid areas of central and western my country. my country's current water-saving and drought-resistant technologies such as sprinkler irrigation, drip irrigation and construction of canals and other large projects Projects, as well as the use of agricultural film covering, rainwater collection and other projects that farmers have the ability to complete independently, but the above water-saving technologies have more or less disadvantages in the application, and the project investment is large. If there is no large amount of financial strength And government support is difficult to achieve. At the same time, there is also waste caused by water loss. The use of agricultural film to save water can save water in a short period of time during the crop growth period, but it involves later processing issues in use, and There are pollution problems, so domestic agricultural and forestry production needs to use new and practical water-saving new technologies

[0003] At present, the fertilizers used by domestic crops are basically inorganic fertilizers, organic-inorganic compound fertilizers and other chemical fertilizers, while the application of humic acid and microbial fertilizers has not been widely used, and the above fertilizers are mainly used alone. The organic combination and synergistic use of effective nutrients can be achieved, but the optimization of the use effect has not been achieved. The continuous use of large quantities of inorganic fertilizers has accumulated in the soil for many years, causing a large amount of salt to remain in the soil, deteriorating the soil, causing compaction, and reducing activity. Reduced fertilizer efficiency

In addition, all of the above fertilizers do not have the function of water absorption, water retention and drought resistance. The dissolution and absorption of inorganic fertilizers, the activation of humic acid, and the growth and reproduction of microbial fertilizer strains are all inseparable from a humid and stable environment. With a humid environment, various effective Nutrients can be fully absorbed and utilized by crops, so that crops are always in a state of water, fertilizer and nutrient balance throughout the growth period

[0004] In addition, although the agricultural superabsorbent resin used in China has a certain water absorption effect, the polymer colloid has poor air permeability and water permeability after water absorption, and it is poorly combined with soil aggregates, decomposed by light, and has a short service life. It is unevenly distributed in the soil and cannot achieve the desired effect, making it difficult to use widely
