Abstract:

In order to investigate the energy dynamic process of greenhouse crops,an experiment based on the best fertilization prescription was made in experimental glasshouse of institute of agricultural engineering of Jiangsu University by the material of Italian lettuce.The results showed that the lettuce energy fixed amount in unit area （1×1 m²） took on a s-shaped curve,and the maximum energy growing rate was daily average 88.86 kJ?m-2?d^-1.
