Comparative studies on light utilization characteristics and shade tolerance of 14 ground cover plants;

This paper introduces the current research status about solar energy utilization of hybrid rice both in domestic and abroad,summarizes the influences of the ecological type and the genotype on the solar energy utilization.

The analysis indicates:the TD and TR is two times larger than contrast,the light energy utilization ration clearly raises,especially middle and lower part lighting quantity raises,the production of the fringe of grain is high,its initial conclusion provides theory basis for wheat/corn plant.

Studies on characteristics of light utilization during the culture of Synechocystis sp. PCC 6803 in airlift photobioreactor

The Study of the Characteristics of Use Outside the Space about Quan Chenglu Jinan Commercial Walking Street;

The model uses the concept of light use efficiency (LUE), while change of air temperature, plant-water deficits and respiration reduce the efficiency of light usage, and the model is modified to couple with the ecology model to better represent regional environmental characteristics of the semi-arid grasslands.

Using remote sensing data and ground meteorological station data,we estimated NPP of grassland during the grow-ing season from 1982 to 2003 in Inner Mongolia using the light use efficiency model proposed by Montieth in 1972,and calculated sever.
