有这样一个例子:黑龙江省呼兰县1980年播种了一批1978年收获的玉米杂交种共30万斤,播种前种子公司做发芽试验,发芽率在80％左右,但生产队在田间种后却没有出苗,双方争吵不休,种子公司又取了样品拿回测定,发芽率仍在80％左右。结果只好双方各负担损失4万元左右。这一例子说明,生产上只测定发芽率还不行,还必须测定种子的活力。 There is such an example: In Hulan County, Heilongjiang Province, a batch of maize hybrids harvested in 1978 was sown a total of 300,000 kg in 1980. Before the sowing, the seed company did the germination test with a germination rate of about 80%. However, But did not emerge, the two sides quarrel endlessly, the seed company takes the sample taken back determination, the germination rate is still about 80%. The result had to bear the loss of 40,000 yuan each side. This example shows that it is not enough to measure the germination rate in production, and the seed vigor must also be determined.
