2531 ZHOU Tian-mei et al. Journal of Integrative Agriculture 2019, 18(11): 2521–2533 to other environmental factors such as water, so it is not suitable to use HI2 to establish a seedling quality model based on TEP. Bai et al . (2014) also provided a range of healthy indexes which can quantitatively and objectively evaluate the quality of tobacco seedlings. There is much less relative research on tomato and cabbage, so studies on a range of healthy indexes for tomato and cabbage may result in a wider and more flexible application of our models. 5. Conclusion We established reliable simulation models of seedling healthy index [(Stem diameter/Seedling height)×Dry mass of seedling] based on TEP for both tomato and cabbage. Both models have fewer parameters, good fitting degree and high predictability. Models can not only provide effective means to predict whether tomato and cabbage seedlings were strong and healthy under certain temperature and illumination conditions, but also provide decision support for temperature and light management of tomato and cabbage seedlings in greenhouses. The same crop can be described by the exponential model with the same parameters, and different crops (tomato or cabbage) need different parameters.
