种植春玉米推行早播早育是抗灾、避灾的主要增产措施。但早播早育常遇低温寡照的影响，种子发芽率低，出苗不整齐，有时低温湿害同时出现，种子易发生冻害，降低出苗率。因此，生产上应特别注意以下四点：　　一、种子平放在湿度较大，温度较低时，搞肥团方块育苗，种子应平放 The planting of spring corn to promote early sowing and early breeding is a major anti-disaster and disaster prevention measures to increase production. However, early sowing and early sowing often encounter the effects of low temperature and low light, seed germination rate is low, irregular emergence, and sometimes low temperature and humidity at the same time, the seed prone to frost damage and reduce the emergence rate. Therefore, the production should pay special attention to the following four points: First, the seeds lay flat on the humidity, the temperature is low, make fat group box nursery seedlings should be placed flat
