Its height ranges from 1 to 3 meters, and its stem is thick and its skin is hard and filling. The leaves fall apart and reach about 1m in length, have hair on the surface, the upper part is tilted back, the lower part is foliage, wrapping around a circle and having no hair. The flowers bloom from July to August, and the Suisak (雄穗) runs at the end of the stem, with several male flowers with only three surgeries.
The female ears run 1 to 3 runs in the middle of the stem, wrapped in 7 to 12 shells, and female flowers with only pistil in them usually run on an even line of 12, 14, and 16. The beard is a pistil and grows out of the shell and receives pollen.
The principle is to modify other households, and it represents a significant hybrid strength. Hwaseo Axis grows 20 to 30 centimeters long and thickens, with many young fruit (穎果: the fruit skin is dried and sticks to the seed skin, and the inside seed is one fruit).
The zodiac has a one-sided, short pointed base, and a diameter of 6mm, which is usually yellow, but has a purple color, and so on the other hand. It has one root, but the root system is well developed, and thick close aides occur in two or three joints near the ground level. There is a theory that it was spread from China, that it was delivered from the Yuan Dynasty during the Goryeo Dynasty, and that it was delivered from the Ming Dynasty during the Joseon Dynasty.
Seed from the beginning of April to the beginning of May, sprinkle two or three eggs, about 60cm in width and 30cm in between the two heads, and then sprinkle them after sprouting and setting them up one by one. The amount of seed required for 10a is 8,9l of the opposing species, 5 to 7l of the neutral species, and 4 and 5l of the subspecies.
Fertilizer gives 1,000 kilograms of compost per 10a, 10 to 15 kilograms of nitrogen, 5 to 7 kilograms of phosphoric acid, 7 to 8 kilograms of calorie and 10 kilograms of lime. When sowing nitrogen, it is recommended to divide it into three parts, 25 to 30 days after sowing, and about 20 days after sowing.
After sprouting, do two or three times of thinning, two or three times of gimmaegi and Bukjugi, and spray insecticide to prevent any harmful effects. Steaming crops are harvested around late July before the skin of the female ears is still green and the seeds are hardened, but grain and feed are harvested from late August to mid-September after the shells are yellow and the seeds are hardened. The variety is classified into eight types depending on the shape and nature of the seed.
The most widely cultivated species in our country are the species, which has large seedlings and hollowed ends like horse teeth, and although there are many crops, most of them are soft, so they are not suitable for eating. A hard species is thick-seed and most of them are keratinous, suitable for eating.
A pyroclastic species is fine-grained, flaky, and suitable for frying. Sweetening species are good for snacks because they are high in sugar and tender. The algal species are malleable starch and are not good for food use.
The almanac is the intermediate property of the series and the sweetening species. Najong is also known as glutinous corn, because starch is almost amylopectin, which is good for snacks. A married species is a primitive form in which each of the seeds is wrapped in a shell. In addition, corn has a significant hybrid strength, so many varieties of corn are cultivated.
