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 cultivation method which successively comprises the steps including seed soaking, plantation, base fertilizer applying, topdressing and foliage dressing, illumination, weeding and completion of harvesting word. The cultivation method disclosed by the invention is characterized in that a seed soaking mixed solution is used to soak corn seeds, so the corn germination rate can be increased, germination and growth can be promoted, corns can be protected from being eaten by worms before the germination, and the germination rate of the corns can be increased; through illumination processing to the corn plants, the growth period can be shortened by 5-7 days, so rush harvesting of the corns can be achieved; the rational plantation density satisfies growth habits of the corns and is suitable for corn growth characteristics, and can satisfy ventilation and light transmission demands during the whole growth course, so row dressing and centralized nutrient use can be achieved, and the corn yield can be increased effectively; and meanwhile, the pesticide dosage is reduced, so the method is green and environment-friendly. In this way, the quality and the yield of the corns are improved; and the corns have plump particles and uniform grains.

Description

Technical field [0001] The invention relates to the field of agricultural technology, in particular to a corn cultivation method. 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 foods for the people in the mountainous areas of northern and southwestern China and other dry valley areas. There are two types of yellow corn and white corn. Among them, yellow corn contains more vitamin A, which is very beneficial to human eyesight. Its nutritional value exceeds that of flour and rice. Regular consumption can prevent arteriosclerosis, cardiovascular and cerebrovascular diseases, cancer, hypercholesterolemia, hypertension and other diseases. In addition to food, corn is also the main raw material for industrial alcohol and shochu. The other parts of the plant are also quite extensive: corn stalks are used for papermaking and wallboard; bracts can be used as filling materials and grass weaving; ...
