Problems solved by technology

The method is simple, but the nutrient elements contained in the prepared water-retaining agent are not very different from the pure water-retaining agent.
[0005] The Chinese invention patent with the publication number CN102977270A discloses a method for preparing an agricultural and forestry composite water-retaining agent, which is obtained through the steps of pretreatment of crop straw, preparation of acrylate solution, preparation of water-retaining agent, washing, and drying. The production process of this invention is complicated. And it only contains crop stalks as an organic matter, and contains less nutrient elements

example 1

[0030] The following mass fractions are added to each component for grinding and concentrated grinding: 0.5% ammonium lauryl alcohol ethoxylate, 0.4% limestone, 0.6% vermiculite, 0.4% calcium superphosphate, 0.4% compound fertilizer, 4% decomposed dry chicken manure , humic acid 15%, white sugar 2%. Polymer materials 68.7%.

[0031] Add the ground mixture into a mixer, and mix it evenly with isocyanate with a mass fraction of 8%.

[0032] The polymer material with a mass fraction of 68.7% is sent into a double-roll extrusion granulator, and then the above-mentioned secondary compound is fed into the double-roll extrusion granulator for extrusion granulation, and dried.

[0033] Send the produced granules to a sieving machine for sieving to obtain a spherical functional water retaining agent.

[0034] The limestone is pure limestone, the compound fertilizer is monoammonium phosphate, the isocyanate is toluene diisocyanate, and the polymer material is sodium polyacrylate.

Abstract

The invention relates to the technical field of crop planting, and specifically discloses a spherical functional composite water retaining agent and a preparation method. The spherical functional composite water retaining agent is capable of improving soil quality and providing needed nutritional ingredients for crops while the spherical functional composite water retaining agent has water absorbing and water releasing functions. The spherical functional composite water retaining agent is prepared from laurinol ammonium ethoxy sulfate, limestone, vermiculite, calcium superphosphate, compositefertilizer, decomposed dry chicken manure, humic acid, isocyanic acid, a high polymer material and white granulated sugar. The preparation method of the spherical functional composite water retainingagent comprises the following steps: mixing the components, and then pelleting, thus preparing the spherical functional composite water retaining agent.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a spherical functional composite water-retaining agent and a preparation method thereof. Background technique [0002] High-molecular water-retaining agent is known as the fourth largest agricultural product after chemical fertilizers, pesticides, and plastic films. It is a type of high-molecular polymer with water absorption and water retention capabilities. The water it absorbs can be slowly released for plants to use. The water retaining agent applied to the soil can improve the environmental condition of the plant root system and the soil interface, directly provide the water supply of the plant, and can also promote soil water retention by improving the soil structure of the plant root system, and indirectly supply the plant water. However, at present, there are few manufacturers of agricultural and forestry water-retaining agents, and they have single functions, irreg...
