Potato seed coating and preparation method thereof

Abstract

The invention discloses a potato seed coating and a preparation method thereof and relates to the technical field of a seed coating. The potato seed coating comprises the following raw materials in parts by weight: 5-8 parts of a bactericide, 7-10 parts of an insecticide, 0.3-0.8 part of hydrocyanic acid, 20-40 parts of nutrients, 12-18 parts of polyglutamic acid, 15-25 parts of trimethoprem, 40-55 parts of plant ash, 28-35 parts of filler and 80-100 parts of water. The insecticide adopts the combination of traditional Chinese medicines, fungi and bacteria, has a strong insecticidal effect, is low in toxicity, achieves the insecticidal effect and has no toxic or side effect to potato seeds; due to the added nutrients, necessary microelements are supplied for the sprouting and growth of potato seeds; due to ferrous sulfide in the nutrients, ferrous sulfate can be prevented from being oxidized; after potato seeds are coated with the coating prepared according to the invention, the anti-microbial property and insect resistance of potatoes can be promoted and the yield and the quality of potatoes can be increased.

Description

Technical field: [0001] The invention relates to the technical field of seed coating agents, in particular to a potato seed coating agent and a preparation method thereof. Background technique: [0002] At present, in the production of seed potatoes, the operation method of manually cutting into pieces by farmers is mostly used, and then the cut potatoes are directly planted. Potato pieces are easy to cause disease transmission among seed potatoes, and there are problems of cut infection and serious soil-borne diseases, which directly affect the yield and quality of potatoes. This traditional potato sowing method affects the emergence rate of seed potatoes in the field, and how to improve the emergence rate of seed potatoes is the key to whether the potato yield level can be improved. At present, two methods of germination sowing and whole potato sowing are often used in potato production to increase the emergence rate of seed potatoes, but the method of germination sowing ...

Problems solved by technology

[0002] At present, in the production of seed potatoes, the operation method of manually cutting into pieces by farmers is mostly used, and then the cut potatoes are directly planted. Potato cubes are easy to cause disease transmission among seed potatoes, and there are problems of cut infection and serious soil-borne diseases, which directly affect the yield and quality of potatoes

This traditional potato sowing method affects the emergence rate of seed potatoes in the field. How to increase the emergence rate of seed potatoes is the key to whether the potato yield can be increased.

At present, two methods of germination sowing and whole potato sowing are often used in potato production to increase the emergence rate of seed potatoes, but the method of germination sowing is restricted by soil moisture. Once the soil is dry for a long time, dry buds will appear

In addition, for areas with serious underground pests, the problem of lack of seedlings and broken ridges caused by insect erosion of stems cannot be solved by relying on these two methods

However, the traditional method of chemical seed dressing and seed soaking to prevent diseases and insect pests has the problems of uneven seed dressing agent and short duration of drug effect.
