Light distribution within forest edges in relation to forest regeneration
advanced planting forest edge light compensation point photon flux density
2015/2/6
Light conditions were measured along six transects from 35 m inside of a mixed Norway spruce/Scots pine forest to an adjoining clear-cut in NW-Austria. Photosynthetic photon flux density (PFD) was rec...
Research of plant type and light distribution of tomatoes determined by imaging technology
Tomato plant type plant spacing light distribution imaging technology
2011/1/12
In order to determine the canopy structure of tomato plants (Lycopersicon esculentum Mill.) that has the advantages of increasing light interception and decreasing planting area, the authors selected ...
基于辐射照度的作物冠层光分布计算系统设计（Calculation System of Light Distribution within Crop Canopy Based on Radiosity Method）
作物冠层 辐射度 光分布 模拟
2009/11/3
以玉米为例，使用C++语言和OpenGL图形函数库，在Windows平台下，开发基于辐射度-图形学结合模型（RGM）的作物冠层光分布计算系统。以相对成熟的RGM方法提取模型参数，并针对作物冠层特点对方法做适当改进。在冠层三维模型基础上，通过用户交互指定参数，可计算出冠层内每个面元的光分布状态。该系统所需模型参数少，且参数均具有较为明确的植物学和农学意义，便于与传统作物模型相结合，操作界面友好、使用...
Effects of Canopy Light Distribution Characteristics and Leaf Nitrogen Content on Efficiency of Radiation Use in Dry Matter Accumulation of Soybean Cultivars
Dry matter production Leaf nitrogen content Light extinction coefficient Radiation conversion efficiency SLW Soybean Varietal difference
2009/7/30
The amount of dry matter produced per photosynthetically active radiation (PAR) intercepted by the canopy (EPAR) and factors which might affect EPAR were determined for various soybean cultivars, and ...
