Because it looks like jade, but it can be eaten, it is called corn.

Rice like jade beads, so it's called corn.

Mexico and Central America are the birthplace of maize, as early as 10,000 years ago, there was wild maize in these places, the Paleo-Indians began to pick wild fruits and transition to artificial corn cultivation at the same time that hunting activities became scarce, and later corn was gradually introduced to China.

Corn origin. Native to Central and South America, corn is an important food crop in the world, widely distributed in the United States, China, Brazil and other countries.

The vitamin content in corn is 5-10 times that of rice and wheat, and the nutritional value and health care effect of corn are the highest among all staple foods.

Corn worship is one of the most important cultural phenomena in Mexico, for Mexicans, corn is not just food, but a sacred object, and has been the object of worship in Indian religion for thousands of years.

Corn is native to Central and South America, and the main corn producing areas in China are the mountainous areas of Northeast, North and Southwest. Today, corn can be grown in most parts of China. Corn is high in vitamins, 5-10 times more than rice and wheat.

It can promote gastrointestinal peristalsis and effectively ** constipation. It also has the effect of benefiting the lungs and calming the heart, strengthening the spleen and appetizing, and diuretic and drenching. However, corn growers can only increase their income if they are carefully managed.

The first thing you need to grow corn is nutrient soil. Mix the fertile soil in the field with organic fertilizer and make nutrient blocks. Then press the corn one by one in the nutrient soil, arrange the nutrient soil neatly, cover it with film, and wait for the corn to germinate.

Then the jade rice seedlings can be transplanted about 10cm. When transplanting, pay attention to covering all the nutrient blocks in the early stage, watering in time, and weeding and insect control at the same time.

The planting of corn should also pay attention to pest control. In order to ensure the green economic benefits of corn, we should take various measures such as agricultural control, physical control, chemical control and biological control in line with the principles of green, safety and health.

South America. Corn was cultivated by the Indians of the Americas 7,000 years ago, and because corn was suitable for dryland cultivation, Western European colonists invaded the Americas and brought corn seeds back to Europe, where they were widely cultivated in Asia and Europe. Around the middle of the 16th century, corn was introduced to China, and in the 18th century to India.

There are many aliases for corn (maize), some places are called yumai, cob, baogu, and there are different names such as jade sorghum, baolu, pearl rice, and six-grain rice. Because the corn was tasted by Emperor Huizong of the Song Dynasty, it won the reputation of "Royal Wheat".

The ancestral home of corn is not in our country. It is generally believed that the origin of corn is in South America. Peru, as it is known, has the saying of "corn barn" in the Indian language.

Archaeologists have found the oldest wild ears of corn in the remains of the Tehuantepec Isthmus in southern Mexico. The ruins of ancient cities are still preserved off the coast of Peru, and a large number of corn kernels and ears are embedded in the excavated pottery and buildings. Analyzing these ruins, archaeologists speculate that the Indians, the earliest inhabitants of South America, began to cultivate corn extensively as far back as 4,000 to 5,000 AD.

In 1492, the Italian navigator Christopher Columbus arrived on the American continent and found corn, which he brought back to Spain that year. In his nautical report, he enthusiastically introduced corn, a crop worshipped by the Indians as a god of nature, writing: "There is a grain called corn, which is luscious and delicious, roasted, and can be made into flour.

Since then, corn has gradually spread all over Europe and all over the world. There may be two ways for South American corn to be introduced to China: one is that the Portuguese brought corn to the claw depression at the end of the 15th century and introduced it to China in the early 16th century; The other was introduced to China by the Arabs through Spain and Central Asia.

Therefore, in the Ming Dynasty, corn was also known as "wheat".

For a long time, corn was introduced to China, but it was only cultivated in some coastal areas and mountainous areas such as Zhejiang and Fujian. Since the 18th century, corn cultivation in China has begun to develop rapidly. Because corn is drought and cold-tolerant, but can be sown in thin soil, it is very adaptable, and soon became a widely cultivated field crop in the plains.

Today, the corn cultivated by the former South American Indians, after long-term natural selection and artificial domestication, has become a high-quality, rich nutritional value of the world's high-yield cultivated plants, occupies an important position in food crops.
