The Dynamic Simulation of Distribution Regularity of Solar Radiation in the Individual Tomato Plant inside the Chinese Solar Greenhouse

摘要

In order to study the radiation regularity of the individual plant inside the Chinese solar greenhouse, the model of plant projection which is based on the geometric structure of tomato is established. In this model, parameters such as, geographic locations, seasons, growing and temporal variations were considered. It has been found that the imitative effect from 10 o'clock to 14 o'clock is better which is based on the error analysis and root-mean-square error detection of different days. Observed values and simulation values in the experimental field from March 28th to April 29th are analyzed by root-Mean-Square Error detection and the RMSE value of azimuth is 1.58 and the RMSE value of plant projected length is 3.38. The model established by this experiment could directly response the distribution regularity of solar radiation in the individual plant inside the Chinese solar greenhouse tomato and the model could provide reference for the solar radiation within the plant population of tomato
