| Abstract: |
| The development process of muskmelon in greenhouse with different water supply was simulated by principal component analysis,and the universal application of the model was tested.The results showed that the logistic model constructed with the comprehensive plant characteristics and effective accumulative temperature had very high precision with the determining coefficient above 0.9.The plant development process in the 3rd trial district was simulated with the model,and the relative error between measured value and fitted value was mostly among 10%.The principal component analysis model had pretty practicality in plant development process simulation with initial information existed fully,and repetition information deleted. |
