近年来水稻生产中,或多或少都会使用一定数量的隔年陈种,用种者几乎每年都有不同程度的反映,突出的问题是发芽出苗不够。浸种催芽技术又不能随购种宣传推广到位,已成现实困难。上年度剩余种子,即使发芽率达标,如果经过一个生产周期或保存环境不善,就很难保持原有芽率不降低。加上用户育秧条件差,又不掌握陈种发芽技术,难免 In recent years, the rice production will use a certain amount of aneuploidy seeds more or less every year, and those who use the seeds reflect it to varying degrees almost every year. The outstanding problem is that the germination is not enough. Seed soaking and sprouting technology can not be promoted with the purchase promotion in place, has become a reality difficult. Last year, the remaining seeds, even if the germination rate, if after a production cycle or poor preservation of the environment, it is difficult to maintain the original bud rate does not decrease. Coupled with poor user nursery conditions, they do not grasp Chen germination techniques, inevitably
