摘要
对利用杂蔸率估算水稻种子纯度的公式进行数学演化后得到了简易的计算公式,在田间只存在单本和两本蔸时,以基本苗为单位的杂株率等于以蔸为单位的全杂蔸率加上半杂蔸率的一半之和。公式的简化为在田间鉴定种子纯度提供了简单、易行的计算方法。实例应用的结果,进一步证实了采用杂蔸率估算种子纯度的有效性和可行性。建议列入杂交水稻种子田间鉴定的标准方法。
The simple formula for estimating rice seed purity using the impurity of rice bunch was deducted. The impurity of seedlings equaled to the sum of the full-impure rice bunches and haft of the half-impure rice hunches. It was very simple to use the method in identifying the purity of rice seed in field. It proved that the method was effective and feasible, and it was suggested to be used as one of the standard methods for identifying purity of rice seed.
