玉米是一种单株增产潜力大的作物，有效收获株数的多少对单位面积产量的影响很大，确保有效收获株数达到９５％左右是玉米高产稳产的基础。要达到这一目的，玉米全苗率应达到９８％以上。如果因干旱、种子质量等原因导致玉米出现缺苗断垄现象，我们应该进行玉米就地起苗移栽，
Corn is a crop with large potential yield per plant. The number of effective harvesters has a great impact on the yield per unit area. Ensuring that the number of effective harvesters reaches about 95% is the basis for high and stable yield of corn. To achieve this goal, corn seedling rate should reach 98%. If due to drought, seed quality and other reasons led to lack of seedling off the phenomenon of maize, we should carry out transplanting of seedlings in situ,
