目前,东北三省区玉米陆续进入出苗期。近日,该区域出现大范围降雨降温过程,个别地区最低气温降至0℃。总体看,降雨对土壤增墒十分有利,有效改善了土壤墒情,大部分地区旱情得到缓解,其中黑龙江、吉林旱情完全解除,为种子萌发出苗提供了良好条件,也为待播地块提供了良好墒情,但个别地块遭受冻害。针对当前玉米出苗形势和气候特点,东北地区应从四个方面着力抓好苗期田间管理。一是适时抢播快种,及时排涝散墒。对没有明显冻害或受冻较轻的地块,进行正常管
At present, three provinces and regions in Northeast China have entered the seedling corn. Recently, a wide range of rainfall-cooling processes have taken place in this area, with the minimum temperature in some areas dropping to 0 ° C. Overall, rainfall is very beneficial to increasing soil moisture, effectively improving soil moisture and easing the drought in most areas. The drought in Heilongjiang and Jilin was completely relieved, which provided favorable conditions for seed germination and emergence, and provided good conditions for the plots to be sown Soil moisture, but individual plots suffer frost damage. In response to the current emergence of corn and climate characteristics, the Northeast should focus on four aspects of seedling field management. First, timely broadcast seeding fast, timely flood drainage moisture. For no obvious frost damage or less cold block, the normal tube
