本文是以旱坡地初果期的酥梨为对象,从田间大量测量叶面积的要求出发,研究了酥梨枝量与叶面积之间的关系。结果表明酥梨技量与叶面积间存在着极显著的正相关(r=0.9337**),可以建立定量预测酥梨叶面积的线性回归方程为:y=148.0894+0.013x用此公式去估计每亩酥梨叶面积与按枝类抽样所得叶面积的符合程度为94.76%,整齐的园片可达98.55%。认为用枝量去定量预测梨叶面积是简便易行的调查研究方法。
Based on the requirement of measuring leaf area in the field, the relationship between the quantity of pear and leaf area was studied. The results showed that there was a significant positive correlation (r = 0.9337 **) between the pear skill and the leaf area, and the linear regression equation for the quantitative prediction of the leaf area of pear was y = 148.0894 + 0.013x. Musk pear leaf area and the branch according to the sampling leaf area of compliance was 94.76%, neat rows of up to 98.55%. It is easy and feasible to investigate the method of quantitatively predicting the leaf area of pear by the amount of branch.
