为了探讨如何防止杂交水稻种子在贮藏期间生活力下降,延长种子使用年限,提高种子利用率,充分发挥良种的增产作用。我公司于1984年将剩余的8万斤杂优种子,使用空气质量调节器(以下简称空调)降温贮藏保持发芽率试验,获得了显著效果,减少了20多万元的经济损失。这批种子于1985年4月下旬按品种取样测定发芽率,除V_(20)A发芽率稍低外,其余平均都在80％以上,有的样品在90％以上,符合生产上用种的质量要求。经各地种植表现,无论从发芽、田间出 In order to explore how to prevent the viability of hybrid rice seeds from decreasing during storage, extend the service life of seeds, increase the utilization rate of seeds and give full play to the yield-increasing effect of elite seeds. Our company in 1984 will be the remaining 8 kg of miscellaneous seeds, the use of air quality regulator (hereinafter referred to as air-conditioning) to cool storage test to maintain the germ, a significant effect, reducing the economic losses of more than 20 million. The germination rate of these seeds was determined by sample sampling in late April 1985, except that the germination rate of V20 (20) A was slightly lower than 80%, and the others were over 80% on average and some samples were over 90% Quality requirements. After planting performance, no matter from germination, field out
