Problems solved by technology

Although this method has increased the yield, it has brought a lot of trouble to cultivation management and mechanical harvesting. Fertilization cannot be mechanized, and it is not conducive to mechanized harvesting.
Moreover, many corn plants are concentrated together, and the water utilization is uneven. In a drought year, the corn is easy to suffer from drought.

Abstract

The invention discloses a corn planting method which includes the steps of seed soaking, planting, base fertilizer application, seedling lifting, top application, foliage dressing, weeding and harvesting. According to the planting method, corn seeds are soaked in mixed solution of ethyl alcohol and garlic juice, effective components in garlic can be completely released in the ethyl alcohol, pests carried in the corn seeds can be effectively killed, and the mixed solution is low in cost and easily obtained. Reasonable planting density conforms to the growth habit of corns and adapts to corn growth characteristics, requirements for ventilation and light penetration in the whole growth process can be met, side dressing and centralized use of nutrients are facilitated, and corn yield can be effectively increased. Besides, dosage of pesticides is decreased, and the planting method is greed and environmentally friendly. Therefore, both the quality and the yield of the corns are improved, and corn particles are plump and uniform.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for planting corn. Background technique [0002] Corn is a common food crop. It has a large sown area in China and is widely distributed. It is one of the main grains for people in northern and southwestern mountainous areas and other dry valley areas in China. There are two types of corn, yellow corn and white corn. Among them, yellow corn contains more vitamin A, which is very beneficial to people's vision. Its nutritional value exceeds that of flour and rice. Regular consumption can prevent arteriosclerosis, cardiovascular and cerebrovascular diseases, cancer, hypercholesterolemia, high blood pressure and other diseases. In addition to eating, corn is also the main raw material for industrial alcohol and shochu. Other parts of the plant are also quite versatile: corn stalks are used to make paper and wallboard; bracts are used as filler material and grass weavi...
