A novel device for measuring and calculating leaf area index relates to a device for measuring and calculating leaf area index and consists of a digital camera (1), an adjustable bracket (2), a leaf carrying plate (3), a computer (4), a leaf pressing plate (5), a pressing bar (6)...
Measurements of leaf area index (LAI) taken with photometers such as the LAI2000 are biased by boles and branches which stop part of the light from reaching the photometer. Estimates were made of how much of the sky would be obscured by boles in an immature stand of Douglas fir (...
Monitoring leaf index of winter wheat using remote sensing was an efficient method to quickly and accurately acquire the growth and spatial distribution of winter wheat at large scales. In this paper we compared the leaf area index(LAI) of winter wheat in March of 2015 and 2016 in Hebi of ...

a conventional hash index is an efficient way of organizing the quota check database87. Such a hash index includes a hash table88of pointers to hash lists89. The size of the hash table88is initially selected as a fraction of the estimated number of inodes in the directory tree. For exampl...

Nonetheless,...
Leaf area indexRainfall interceptionIn precision agriculture, methods for analysing 3D point clouds of plants have been introduced, particularly pointing to the high accuracy of light detection and ranging (LiDAR) laser scanning under field conditions. In the present work, LiDAR-based 3D point clouds...
