Description

A kind of cowpea seed treatment agent and treatment method thereof

technical field

The invention relates to the technical field of crop cultivation, in particular to a cowpea seed treatment agent and a treatment method thereof.

Background technique

Cowpea is an important economic crop in my country and one of the home-cooked dishes that are loved by people. It has the functions of nourishing Qi, invigorating the stomach, nourishing the kidney, regulating the appearance and body, harmonizing the five internal organs, nourishing the essence, quenching thirst, and detoxifying. Cowpea seeds contain a lot of starch, fatty oil, protein, niacin, vitamins B1 and B2. Dried beans contain a lot of plant fiber, and also have the effect of laxative.

Seed treatment refers to the general term for physical, chemical or biological treatment measures used before sowing seeds, with the purpose of promoting fast and neat germination of seeds, robust growth of seedlings, prevention of pests and diseases, and early maturity of certain crops. Treating cowpea seeds before sowing can eliminate fungi and bacteria attached to the seeds and prevent germs from being brought into the field during sowing, which plays an important role in increasing cowpea production and preventing pests and diseases.

The existing cowpea seed treatment agent has the problems of poor treatment effect, short duration, great harm to human body and environmental pollution, poor film-forming property and bonding strength of the seed coating agent, and the like.

The invention discloses a cowpea seed treatment agent and a treatment method thereof. A non-photocatalyst is added to the seed treatment agent. The main component of the non-photocatalyst is an ultra-nanometer micromolecular titanium dioxide phosphate compound, which has extremely strong sterilization and anti-mildew functions in both the light and non-light states. Nano-silver is added to the seed treatment agent. A very small amount of nano-silver can produce a strong bactericidal effect, which can kill more than 650 kinds of bacteria within a few minutes. It is broad-spectrum bactericidal without any drug resistance and no toxic reaction. Is the latest generation of natural antibacterial agents. Antimicrobial peptides are added to the seed treatment agent. Antimicrobial peptides have the advantages of high antibacterial activity, less resistance to mutations, and good thermal stability. They have strong killing effects on some fungi, protozoa, and viruses. The wood vinegar is added to the seed treatment agent, and the wood vinegar has the functions of sterilization, disinfection and insect repelling because it contains many phenolic substances. Soaking the cowpea seeds with the cowpea seed treatment agent can effectively kill fungi, bacteria and pests attached to the cowpea seeds without drug resistance. The water-retaining agent is a functional polymer material with particularly strong water absorption capacity. It is non-toxic and harmless. It can release and absorb water repeatedly, and can also absorb fertilizers and pesticides and release them slowly, increasing the fertilizer and drug effects. Covered with polyvinyl alcohol film containing fungicides, insecticides and water-retaining agents. The polyvinyl alcohol film has the advantages of good film formation, fast drying, strong adhesion, and does not affect seed germination. Through the degradation of polyvinyl alcohol With the function of water-retaining agent, the active ingredients such as fungicides and insecticides are slowly released, which can protect cowpea seeds from bacteria, fungi and pests for a long time.
