Corn has been cultivated for more than 470 years in China. However, due to the high yield, good quality and strong adaptability, the cultivation area develops rapidly. At present, China`s sown area is about 300 million mu, next only to rice and wheat, ranking the third in food crops. Second only to the United States in the world. China has also accumulated rich experience in corn cultivation technology. The corn plant is tall, the grain and stem leaf yield is high, and the management is fine. Fertilization, irrigation, chemical weeding and pest control are the key technical measures in high-yield cultivation and management of maize.
