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 planting method of selenium-rich corn. The planting method comprises the steps of seed soaking, land selecting for planting, base fertilizer applying, topdressing applying, selenium fertilizer applying, weeding and harvesting. According to the planting method, the reasonable planting density meets the growth habit of corn and adapts to the growth characteristics of corn, the requirements for ventilation and light permeation needed in the whole growth process can be met, side dressing and concentrated nutrient application are facilitated, and the corn yield can be effectively increased. Meanwhile, the using quantity of pesticides is reduced, and environmental friendliness is achieved. In this way, the quality and yield of corn are both improved, and corn grains are plump and even. In addition, the using quantity of applied selenium raw materials is small, the cost of the whole production process is low, the produced corn is high in nutritive value and high in selenium content, and ordinary corn becomes extremely special functional food.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for planting selenium-enriched 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 materi...
