摘  要:
基于实测的叶面积与叶长和叶宽数据,对甘薯叶面积简便测定方法进行了研究。结果表明:公式法的测量平均相对误差7.2%,显著高于叶面积仪测定法的平均相对误差2.8%,但其准确程度亦能够满足甘薯叶面积测定的精度要求,且具有操作简便、成本低廉和实用性强的优点。

摘  要:
Methods of leaf area calculation were investigated for sweet-potato leaves,based on the measurement of length-width multiplication method.The results showed that the precision of formula calculating method which average relative error was 7.2%,was higher significantly(P<0.05).Than that of the leaf area meter method which average relative error was 2.8%,but it also satisfy the precision demand for the mensurationset of sweet-potato leaves.Furthermore,the formula calculating method was a good measurement because of its simple manipulation,cheap cost and better practicability.
