在玉米大面积种植区，播种后的发芽率经常受气候、播种质量等因素的影响，常常造成发芽率降低而影响全苗，为了确保苗全、苗齐、苗壮。据前有必要进行一次室内发芽试验。据东光县种子监督检验站1997年试验结果表明：室内种子发芽率与田间出苗率和幼苗健苗率有着较高的正相关关?
In a large area of corn planting, the germination rate after sowing is often affected by climate, sowing quality and other factors, often resulting in lower germination rate and affect the whole plant, in order to ensure that the whole plant, seedling Qi, Miao Zhuang.
