Where are the latest growing regions for black corn? An overview of the main production areas
Black corn is a special type of corn. Unlike other corn, whose color is yellow, black corn is entirely black, mainly because black corn is rich in melanin. It also contains nutrients such as plant protein, amino acids, and trace elements. Its overall nutritional content is somewhat higher than that of ordinary corn. Even the nutrient content of the corn plant itself is higher than that of ordinary corn, making it more suitable for use as animal feed. So this black corn is not common either. Where are its main growing regions? Let's introduce them right away.
1. Main growing regions
Black corn is suitable for planting in most areas, but at present it is only planted in the northern regions of Liaoning and Anhui, the southern region of Guangdong, the southwestern region of Sichuan, and the northwestern region of Xinjiang. These areas have already widely promoted its cultivation. In other areas, it is only planted on a small, scattered scale. Some areas are still in the process of trying to grow it. So the main growing regions are now these places.
2. Cultivation methods
For spring sowing, the entire growth period is about 4 months, and about 2500 plants are grown per mu. The planting soil should be fertile and loose. The base fertilizer is about 1000 jin per mu. It needs to be planted in special isolation to avoid receiving pollen from ordinary corn and producing mixed kernels. The main method is spatial isolation, staying far away from other fields, or staggering the flowering period in terms of planting time. The main pests to control are corn borers and cutworms, using carbofuran for control. Buy packaged seeds; generally direct sowing is enough, and after the land is leveled, sowing can begin. After sowing, long-term management is needed.
3. Nutritional value
It is mainly very high in lysine and has high nutritional value; among trace elements, its potassium content is the highest. Eating more black corn can stabilize mood and help prevent cardiovascular and cerebrovascular diseases. It contains more iron and is suitable for people with anemia. Its zinc content is relatively high and is suitable for children to eat, helping prevent zinc deficiency, as children are very prone to zinc deficiency. It can help prevent the adverse effects brought by zinc deficiency, such as improving resistance and improving anemia. Its main calcium and phosphorus components are suitable for children with calcium deficiency and for middle-aged and older adults. The melanin it contains mainly helps lower cholesterol and has a health-protective effect on the cardiovascular and cerebrovascular systems.
4. Appearance characteristics
Some people previously thought that black corn was genetically modified food, could not be used 2, and was not good to eat, but in fact black corn is just a type of corn. Or rather, a category. It is black simply because its melanin content is relatively high. General black corn has an appearance of glossy black kernels, but some are white near the attachment site. Some look as if they have a dark red tint.
Black corn can be planted in most places, but currently it is only widely promoted and planted in these few places, while some other places are also trying to grow it. In the future, the planting area will gradually expand. Total output will also increase.
