任意不规则膜片面积的测量是工农业生产和科研工作中经常遇到的一个问题。尤其是农、林业生产中研究光合作用与植物生长、农林作物的产量之间的关系以及环境污染、病虫害等因素对作物叶片损害程度等实际问题均遇到面积测量问题。目前国内除少数中央、省级科研单位引进国外面积测试仪测量外(测量误差在1%左右),还有相当多的农村科技工作者仍用经验系数估算法、秤重法、方格纸数数法等来测量叶片面积。鉴于
The measurement of any irregular patch area is a problem often encountered in the industrial and agricultural production and scientific research. In particular, in agriculture and forestry production, the relationship between photosynthesis and plant growth, the relationship between the yield of agricultural and forestry crops, and the actual problems of environmental damage, pest and disease damage to crop leaves are all encountered in area measurement. At present, except for a few central and provincial research institutes, the measurement of foreign area is introduced (the measurement error is about 1%), and a considerable number of rural scientists still use the empirical coefficient estimation method, the weighing method and the number of graph paper Number method to measure the leaf area. Given that
