Problems solved by technology

Most of the existing insecticides on the market are water or powder, and the insecticidal effect is achieved through chemical components. The spraying of pesticides in high temperature weather can easily cause human poisoning
The conventional utilization rate of chemical pesticides is only 50% to 60%, and there will be a large amount of pesticide residues in plants, which not only causes waste of resources, but also causes serious environmental pollution

Abstract

The invention provides a humic acid type insect-resistant pheromone water-absorbent resin and a preparation method thereof. The humic acid type insect-resistant pheromone water-absorbent resin is prepared from the following raw materials in parts by mass: 8-10 parts of humate, 6-8 parts of cellulose, 10-12 parts of a hydrophilic monomer, 2-4 parts of terpenoid insect-resistant pheromone, 0.5-0.7 part of an initiator and 0.1-0.2 part of a cross-linking agent. The preparation method comprises the following steps: dissolving cellulose and humate in water, fully mixing, adding the hydrophilic monomer, the initiator, the cross-linking agent and the terpenoid insect-resistant pheromone while heating and stirring at 40-50 DEG C, heating to 60-75 DEG C, and carrying out cross-linking reaction for 2-3 hours to obtain the humic acid type insect-resistant pheromone water-absorbent resin. The method is simple to operate and environment-friendly; and the super absorbent resin prepared by the method not only can enable plants to have the effects of resisting diseases and insect pests, resisting bacteria, resisting cold and the like, but also can effectively relieve environmental pollution and harm to animals and plants caused by use of chemical pesticides.

Description

Technical field [0001] The present invention belongs to the field of agricultural fertilizers, and in particular, the present invention relates to a water-absorbent resin of humic acid-type anti-sepage phenotropin and its preparation method thereof. Background technique [0002] At present, insecticides in the market are chemical pesticides, such pesticides can be targeted by most pests, but there is a problem. Most of the insecticides in the market are water agents or powders, and the chemical composition reaches insecticidal effects, and the high temperature weather is easily sprayed to pesticides. The routine utilization rate of chemical pesticides is only 50% to 60%, and there will be a lot of pesticide residues in plants, which not only causes waste of resources, but also causes serious environmental pollution. Inventive content [0003] In order to overcome the defects of chemical insecticidal existence, it is an object of the present invention to provide a hydrolytic acid...
