播种成苗是关系到作物生产、种子生产成败的首要环节。长期以来,人们多用发芽率来衡量种子的播种品质,但生产中常遇到发芽率与田间出苗率不相符的情况,由此,人们便试图寻找一种能准确预测种子田间出苗情况的指标,从而提出一个新的概念—种子活力。
Sowing seedlings is the primary link that relates to crop production and the success of seed production. For a long time, many people use the germination rate to measure the sowing quality of the seeds, but the production often encounters the germination rate and the field emergence rate does not match the situation, therefore, people will try to find a can accurately predict seedling emergence of the indicators, and thus Proposed a new concept - seed vitality.
