目前,中低产田在辽宁省仍占有较大的比例,中低产田农业基础设施条件差,土壤瘠薄,抗灾减灾能力差,农民种植及田间管理水平低,粮食生产潜力未得到充分发挥。要实现玉米持续增产,必须充分挖掘中低产田的增产潜力,狠抓中低产田玉米关键技术与措施的推广与应用。1中低产田玉米增产关键技术1.1选用良种中低产田玉米品种选用要注意稳
At present, middle and low-yielding fields still occupy a large proportion in Liaoning Province. Low and middle-yielding agricultural infrastructure, poor soil, poor ability of disaster prevention and mitigation, low level of farmers’ planting and field management, and insufficient potential of grain production have been fully realized. To achieve continuous increase in corn production, we must fully tap the yield potential of middle and low yield fields, and pay close attention to the promotion and application of key technologies and measures in middle and low yield fields of corn. 1 middle and low yield field corn yield key technology 1.1 selected varieties of middle and low yield field corn varieties should pay attention to stability
