Abstract

The invention relates to the technical field of seed coating agents, in particular to a coating agent for corn seeds and a treatment method for corn seeds. By utilizing the super strong water retention effect of polyaspartic acid and the ability to enrich nitrogen, phosphorus, potassium and trace amounts of Elements, for the characteristics of seed nutrition supplement, combined with the addition of dimethyl sulfoxide and sodium carboxymethyl starch, not only makes it easy to pellet the corn seed coating process, but also enables its penetration and The synergistic performance is strong, and it can achieve synergistic effect with polyaspartic acid, so as to prevent the corn seeds from being damaged by chilling, and at the same time ensure that the corn seeds can be supplemented with water to enhance the ability to resist drought; In the semi-arid soil, the water retention capacity around the corn seeds is strong, combined with the action of dimethyl sulfoxide, the cold resistance ability is enhanced, the germination rate of corn seeds is guaranteed, and the effects of strong roots and seedlings and stress resistance of corn are enhanced.

Description

technical field [0001] The invention relates to the technical field of seed coating agents, in particular to a corn seed coating agent and a corn seed treatment method. 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. 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 and industrial raw material, and its status is increasingly important in my country's national economy and people's life. [0003] my country's main corn producing areas are in the north, but due to poor climatic conditions during corn sowing, such as drought and water shortages, the germination rate of corn seeds is low, and the growth at the seedling stage is weak, which affects the corn yield. Warm crops, the effective accumulated temperature from sowing to emergence is 79.8 °C, and the biological lower limit temperature is 9.3 °C. When th...
