前言黑龙江省作物生育期较短,玉米收获时,果穗含水量较大,尤其是栽培的晚熟品种,常不及充分干燥,严寒即降临,保管不当常使种用玉米发芽力大为降低。生产上常被迫利用发芽率低的玉米种子播种,结果,浪费了大量种子,又常造成缺苗,使玉米生产受到一定影响。如何利用发芽率低的种用玉米,是黑龙江省部分地区目前玉米生产中值得 Foreword Heilongjiang Province crop growth period is short, corn harvest, the ear larger water content, especially the cultivation of late-maturing varieties, often less than full drying, cold is coming, improper storage of corn germination often greatly reduced. Production is often forced to use low germination rate of corn seed sowing, resulting in a lot of waste of seeds, often resulting in lack of seedlings, corn production will be affected. How to use low germination rate of corn, is part of Heilongjiang Province, the current corn production is worth
