Alternative names for corn include: stick, bracts, bracts, bracts, bracts, yucca, pearl rice, corn, large rushes of corn, pearl kernels, barley kernels, and corn, among others.

I, corn introduction

Corn is a short-day crop, like warm and rainy climate. During the growing period, corn needs to constantly absorb water to keep its growth and development proceeding normally. Generally speaking, corn consumes a large amount of water, so if there is insufficient precipitation or insufficient irrigation water, it may result in reduced or even extinct corn yields. Also, corn needs an environment where the first frost comes later in the fall to fully mature.

Second, corn morphology

Morphology of corn is characterized as a tall annual herb with erect, usually unbranched culms and basal nodes with aerial strut roots.

Leaf sheaths with transverse veins, ligules membranous, ca. 0.2 m long, leaf blades flattened and broad, linear-lanceolate, base rounded auriculate, glabrous or blemish-pilose, midvein stout, margins scabrid ca. 1-1.5 m long. The caryopsis is globose or oblate, with the glumes and lemmas exposed at maturity, and varies in size according to the growing conditions.

The significance of planting maize:

One, food supply

Maize is one of the main food crops for the people of the world and our country, especially in Asia, Africa, and Latin America, where maize is widely planted, and it is the main source of food for the people of these regions. In our country, corn is the third most important food crop after rice and wheat. Therefore, the cultivation of maize is of great significance to safeguard the global and China's food supply.

Two, economic value

Corn not only has food value, there are a wide range of industrial uses. Corn can be used as livestock feed, but also an important industrial raw materials, can be used to produce starch, alcohol, sugar and so on. Especially in recent years, with the development of corn deep processing and used as a biofuel - ethanol, the proportion of industrial use of corn is a clear trend of increasing.

Three, ecological value

Corn is a photosynthesis efficiency, respiratory consumption of dry matter at least the crop, its high yield, regenerative capacity, these characteristics make corn has a high ecological value. In addition, corn is also a crop with multiple functions such as production, life and ecology, which is important for maintaining ecological balance and sustainable development of agricultural production.
