Embodiment 1
[0064] The cold-resistant corn seed coating agent includes the following components: 0.5 parts by weight of dimethyl sulfoxide, 1 part by weight of proline, 6 parts by weight of 70% imidacloprid water dispersible granules, 2 parts by weight of gum arabic and 90.68 parts by weight The dosage form of the 70% imidacloprid water dispersible granules is water dispersible granules, and the active ingredient content is 70%. The manufacturer is Bayer Crop Science Co., Ltd., and the packaging company is Bayer Crop Science (China) Co., Ltd.
[0065] The preparation and application method of cold-resistant corn seed coating agent are as follows:
[0066] Mix the above-mentioned raw materials according to the above ratio to prepare a mixed jelly solution, pour the prepared coating agent into the container, dress the coating agent and the corn seed in a ratio of 1:30, and stir thoroughly to make the coating agent It is evenly attached to the corn seeds. Due to the viscosity of the solution, a d...

Abstract
The invention relates to a cold-resistant corn seed coating agent, which comprises the following components in parts by weight: 0.5-5 parts of dimethyl sulfoxide, 0.05-1 part of proline, 6 parts of 70% imidacloprid water dispersible granules, 2 parts of Arabic gum and 81.28-90.68 parts of water. The cold-resistant corn seed coating agent provided by the invention can form an active material warehouse around corn seeds, mainly used in the time period that corn seeds are sown for about one month, has the effect of cold resistance, and promotes seed germination; the germination rate and germination potential of corn seeds treated through the cold-resistant corn seed coating agent are increased, seedling dry weight is increased, the root growth in the corn seedling stage is promoted, roots are enabled to be increased and thick, the root shoot ratio and the seedling height are increased, the cold resistance of the corn seeds is improved, the corn seeds can resist cold damage, sown in the soil with moisture, can be sown early, and sprout early, the photosynthesis during the corn growth period is increased and the purposes of high yield and stable yield are achieved.
Description
Technical field [0001] The invention relates to a seed coating agent, in particular to a cold-resistant corn seed coating agent. Background technique [0002] Corn is one of the important food crops in my country. The sown area is second only to rice and wheat, ranking third. The output accounts for about 25% of the country's total grain output and 90% of the total coarse grain output. Corn is the main feed grain and industrial raw material, and its position in my country's national economy and people's lives has become increasingly important. Northeast China is the main producing area of spring corn in my country. Ensuring high and stable corn production is of great significance to ensuring food security, increasing farmers’ income, reducing currency expectations, and maintaining social stability. Studies have shown that corn is a typical temperature-loving crop. The effective accumulated temperature from sowing to emergence is 79.8℃, the biological lower limit temperature is...
