Abstract

The invention discloses a method for eliminating or reducing surface viscosity of bionic glue by using curing agents. The method comprises the following steps: spraying the curing agents on the surface of a plant which is sprayed with the bionic glue before the plant is harvested so as to eliminate or reduce the viscosity of the bionic glue; and then, carrying out other farming operations or harvests. The invention also discloses a corresponding liquid curing agent and a corresponding solid curing agent, wherein the liquid curing agent comprises the following components: 10-50% of poval, 0.05-0.1% of surfactant and the balance of water; and the solid curing agent is inert powder such as diatomite, zeolite powder, kaolin, attapulgite clay, molecular sieve or the like. The method disclosed by the invention has a good effect, and can obviously reduce the viscosity of the bionic glue; moreover, the curing agents disclosed by the invention are degradable materials or natural products, and are harmless to plants, animals and environment; and the liquid curing agent disclosed by the invention has a good waterproof property, and rainfall does not obviously influence the effect on reduction of the viscosity of the bionic glue.

Description

technical field [0001] The invention belongs to the field of plant disease and insect pest control, and in particular relates to a method for eliminating or reducing the surface viscosity of bionic glue by using a curing agent and a curing agent thereof. Background technique [0002] The use of bionic technology to prevent and control plant diseases and insect pests is a method that has no effect on the growth, yield and quality of plants, but can reduce environmental pollution caused by pesticides and protect biodiversity. The Chinese patent "A Method of Preventing and Controlling Plant Diseases and Pests Using the Principle of Bionics" (Patent No.: ZL 200710030382) discloses a method of spraying sticky glue on the surface of plants using an atomizer to stick harmful organisms to the glue, so as to prevent its harmful purpose. This method can effectively control the number of pests in the growing season, but the stickiness produced by the biomimetic glue will cause inconve...
