preparation example Construction

[0020] A preparation method of a stable seed coating agent, comprising the steps of:

[0021] 1) Grinding sodium alginate, humic acid, and organic silicon through a ball mill, passing through a 200-mesh sieve, and sieving to remove impurities;

[0022] 2) Add urea, ethylene glycol, and xanthan gum to the above components, mix evenly, and add 50% of the total amount of water, stir evenly, raise the reaction temperature to 80-100°C, and react for 3-5 hours;

[0023] 3) Add colloidal dispersant, antifreeze and sucrose in sequence, put them into a centrifuge, centrifuge at a rotation speed of 1000-1500r / min, and take the supernatant;

[0024] 4) Disperse copper sulfate, bitter gourd extract, potassium sulfate, wetting and dispersing agent, and preservative in the remaining water evenly, and cut it with a shearing machine for 10-15 minutes.

[0025] 5) Add agar and the rest of the water, stir evenly, and test the fineness to meet the requirements.

Abstract

The invention discloses a stable seed coating agent, which is prepared from 1 to 3 parts of sodium alginate, 0.5 to 0.9 part of agar, 3 to 9 parts of urea, 4 to 10 parts of humic acid, 6 to 8 parts of ethanediol, 0.5 to 0.9 part of xanthan gum, 3 to 5 parts of organic silicon, 2 to 5 parts of colloidal dispersants, 5 to 9 parts of antifreeze agents, 10 to 15 parts of saccharose, 3 to 8 parts of copper sulfate, 4 to 6 parts of potassium sulfate, 0.5 to 1.0 part of wetting dispersants, 2 to 3 parts of preservative and the balance water to reach the total amount of 100 parts. By using the technical scheme, the bitter gourd extracts, the saccharose and the like are added into the formula ingredients; the stress resistance of the whole compound is improved, so that during the planting after the seed coating by the seed coating agent, the performance is stable; the dispersion by the soil is not easy; the medicine effect is durable; the germination rate is ensured.

Description

technical field [0001] The invention relates to the field of pesticide manufacture, in particular to a stable seed coating agent and a preparation method thereof. Background technique [0002] On the outside of the plant seeds in a dry or wet state, they are coated with a binder-containing pesticide or fertilizer to form a protective layer with certain functions and coating strength. This process is called seed coating. , and the original composition coated on the outside of the seeds is called a seed coating agent, and its notable feature is to have a relatively firm outer layer. [0003] The main purposes of seed coating are different, mainly in the following three aspects, 1) It is mainly used to coat seeds with biologically active substances such as pesticides and fungicides and their mixtures to eliminate harmful organisms, provide nutrition, and promote growth The seed coating agent for the purpose of development, 2) mainly use water-retaining agent, polymer semi-perm...
