玉米是种植最广泛的谷类作物,在世界谷物总产量中位居第二,仅次于小麦。其在我国是第二大作物,仅次于水稻。玉米是饲料之王、加工原料之王,是畜牧业赖以发展的重要基础,是不可替代的雨养旱地主栽作物。当前随着土地不断减少、人口不断增加,粮食安全问题日益突出,玉米需求量随之不断增加,因此需要不断提高产量。而且高产是玉米生产永恒的主题,只有通过科技创新,不断实现玉米单位面积的高产,才能大幅度地提高玉米总量,这对保障我国粮食安全、食品安全、能源安全及生态环境安全都有重要意义。
Corn is the most widely grown cereal crop, ranking second in the world in terms of total cereal output, second only to wheat. It is the second largest crop in our country, second only to rice. Corn is the king of feed and the king of processed raw materials. It is an important foundation for the development of animal husbandry and an irreplaceable rain-fed dryland. At present, as the land is declining, the population is increasing, the issue of food security is becoming increasingly prominent, and the demand for maize continues to increase, it is necessary to continuously increase the output. Moreover, high yield is the eternal theme of corn production. Only through scientific and technological innovations and continuous realization of high yield per unit area of corn can the total amount of corn be greatly increased, which is important for ensuring food security, food safety, energy security and ecological security in our country significance.
