玉米是辽宁省的主要粮食作物,常年种植面积133万hm~2左右,玉米总产量基本稳定在1000万t,种植面积和产量分别占全省粮食作物的44%和60%,在辽宁省粮食生产中占有重要地位,但由于玉米生产成本较高,收益较低,人工点种,农民劳动强度大,这些因素大大制约了玉米生产的发展。最大限度降低玉米生产成本,提高玉米种植的比较效益,减轻劳动强度,是农机工作者面临的一项重要任务。为了解决这一问题,辽宁省农机总站引进
Corn is the main food crop in Liaoning Province. The perennial planting area is about 1.33 million hm ~ 2. The total output of maize is basically stable at 10 million t. The planting area and output respectively account for 44% and 60% of the province’s food crops. In Liaoning Province, Production occupies an important position, but due to the higher cost of corn production, lower yields, artificial species, farmer labor intensity, these factors have greatly hampered the development of corn production. Minimize the cost of maize production and improve the comparative benefits of corn cultivation, reduce labor intensity, is an important task facing agricultural workers. In order to solve this problem, Liaoning Provincial Agricultural Terminals introduced
