Precision sowing of corn seeds has become a trend in recent years, reducing seed sowing, seedling labor and expenses in the field, but also brought profits to the enterprise. How to better produce seeds that are more conducive to the emergence of seedlings in the field and improve the seedling establishment rate in the field provide the basis for ensuring the whole seedlings. Adapting large-scale planting operations has become the research focus. To this end, we conducted a corn seed grading laboratory test. 1 Materials and methods 1.1 Materials The tested varieties were Zhengdan 958 produced by Henan Golden Doll Seed Industry Co., Ltd. in October 2011 and Hao Yu 20 produced by Jilin Hao Seed Company.
