受光叶面积指数测定
determination of lighted leaf area index
shouguang yem一anji zhishu eeding受光叶面积指数测定(determination oflighted leaf area index)生长状况观测项目之一，是对受到太阳直接辐射照射的叶面积(用叶面积指数来表示)的侧定(见叶面积测定)。测定目的在于鉴定光能在作物群体中分布的合理性和有效性;预测其对产量的影响。测定时首先分层测定受光面积率。一般采用棒测法，即用一根110厘米长的木尺，其上每隔1厘米点一红油漆点(共100个点)，将它水平放置在欲测的层次高度上，与作物行间垂直，并固定在支架上，随后数它被阳光直接照射的亮点(红漆点)数。在同一高度上，用同样的方法，每间隔10厘米左右移动测尺一次，共测十次，算出总亮点数，然后除以1000，便求得该层受光面积率(百分率)。中国已研制出直射透光率测定仪，其棒状感应器为1米长，由100个感应器件组成，用它在作物群体内进行快速扫描，直射光透光率由数码直接显示。作物冠层的垂直分层，对于矮秆密植作物(如稻、麦)，一般从地面向上每10厘米为一层，而稀植高秆作物(如玉米)，一般每20一30厘米为一层。测定时，按照划分好的垂直层次标志，由上向下逐层分别测得各层的受光面积率。其次，分别测出各垂直层次间的叶面积密度(见叶面积密度测定)。最后，求算群体受光叶面积指数。某层叶面积密度乘以该层的受光面积率就是该层的受光叶面积指数。(林家栋)
