Technical Field

The invention relates to the technical field of seed cultivation, in particular to a method for improving the germination rate of corn seeds.

Background

Corn is one of the most widely planted crops in world agriculture, and is known as the 'gold' industry as three major food crops due to its abundant output and high available value. Corn seeds are generally treated in order to improve the germination rate, and the existing treatment methods are various, such as a hanging well method, a refrigeration method, a sand mixing method and the like. Different treatment modes correspond to different effects, the conventional treatment methods can improve the germination rate of seeds to a certain extent, shorten the germination time and reduce the field morbidity, seedlings are uniform and strong, but the conventional treatment methods all need a grower to purchase corn seeds and then carry out self-treatment, the treatment method of the grower is unskilled, the materials are not uniform, so that the corn seeds are not well treated, the production intensity of the grower is improved, and the production cost of the grower is increased.

Therefore, we propose a method for increasing the germination rate of corn seeds to solve the above problems.
