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.

Embodiment 1

[0024] A method for cultivating pollution-free corn, comprising the steps of:

[0025] (1) Select seeds with a germination rate of more than 95%, dry them for 1 day 15 days before sowing, soak them in water for 10 hours one day before sowing, and then use the mixed seed soaking solution to mix with corn seeds according to the weight ratio and soak them together for 10 hours. Rinse with warm water at 33°C every morning and evening until the corn seeds germinate;

[0026] (2) Divide the corn planting into multiple planting groups, plant two rows of corn in each planting group, and plant the two rows of corn alternately, the distance between the corn in each row is equal, and the distance between each two planting groups is 50cm, and each The distance between two rows of corn in each planting group is 30cm, the distance between the rows of corn in each row of corn is 7cm, the sowing depth is 8cm, 2 seeds are sown in each hole, and 30g of sodium bicarbonate aqueous solution with a...

Abstract

The invention discloses a cultivation method of nuisance free corn, comprising the steps: seed soaking, planting, basal dressing, top dressing, foliage dressing, hole application, foliage dressing, weed clearing and harvesting. According to the cultivation method disclosed by the invention, corn seeds are soaked in a mixed solution for seed soaking, so that the bud ratio of corn can be improved, germination and growth are promoted, and corn can be prevented from being eaten by vermin before germination to improve the bud ratio of the corn; a reasonable planting density conforms to the growth habit of corn, adapts to the growth characteristic of corn, can meet the requirements for ventilation and light transmission in the whole growing process, is favorable for side dressing and centralized employment of nutrients, and can effectively increase the yield of corn; and simultaneously, the consumption of pesticides is reduced and greenness and environmental protection are realized. Therefore, both the quality and yield of corn are improved and the corn is full and uniform in grains.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating pollution-free 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...
