Cold-resistant corn seed coating agent

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 most important food crops in my country. Its sown area is second only to rice and wheat, ranking third. Its 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 status in my country's national economy and people's life is becoming increasingly important. Northeast China is the main producing area of ​​spring corn in my country. Ensuring high and stable corn yields is of great significance to ensure food security, increase farmers' income, reduce currency expectations, and maintain social stability. Studies have shown that maize is a typical temperature-loving crop. The effective accumulated temperature from sowing to emergence is 79.8°C, and the biological lower limit temperature i...

AI Technical Summary

Problems solved by technology

Studies on enhancing the cold resistance of corn generally focus on soaking and spraying seeds in solutions (pharmaceuticals, trace elements, hormones, etc.), low-temperature training of seeds, stimulation by electricity, magnetism, and heat, PEG triggering, infiltration of organic solvents, and pelleting of seeds, etc. However, none of these can fundamentally change the harm of low temperature to corn growth
