玉米是世界三大粮食作物之一,不仅可以作为粮食,还可以加工饲料,目前我国已形成三大玉米主产区,一是北方玉米区,包括吉林、黑龙江、辽宁、内蒙古等省区;二是黄淮平原春夏玉米区,包括山东、河南、河北等省;三是西南丘陵玉米区,包括云南、贵州等省。三大主产区的玉米种植面积达到全国80%以上,随着农业机械化的发展,玉米种植面积逐年增加,但是国内目前玉米的收获技术落后,制约了玉米生产发展,加快玉米收获机械化的发展已成为当务之急。
Corn is one of the three major grain crops in the world. Not only can it be used as food but also feed for processing. At present, China has formed three main producing areas for corn. One is the northern maize area including Jilin, Heilongjiang, Liaoning and Inner Mongolia. Huanghu plain spring and summer maize area, including Shandong, Henan, Hebei and other provinces; third is the southwest hills corn area, including Yunnan, Guizhou and other provinces. With the development of agricultural mechanization, the acreage of corn is increasing year by year. However, the harvesting technology of maize in current China lags behind and restricts the development of corn production and accelerates the development of corn harvesting mechanization. Become a top priority.
