在生产实践中,烤烟的育苗期常常长达70d,不仅带来苗床管理用工耗时多,而且因播种期过早,苗床温度较低而引起大量烂种。为了探索烤烟种子在不同温度下发芽情况,为烤烟确定播种期提供依据,2006年8月12日至11月2日,我站进行了烤烟种子发芽试验。
In production practice, the flue-cured tobacco seedling often up to 70d, not only bring the seedbed management and labor-intensive, but also because of premature sowing, seedbed temperature caused by a large number of rotten. In order to explore the germination of flue-cured tobacco seeds at different temperatures and provide the basis for determining the sowing date of flue-cured tobacco, we conducted the flue-cured tobacco seed germination test from August 12 to November 2, 2006.
