    摘要:

    為研究不同密度下溫室番茄的生長(zhǎng)行為，對(duì)結(jié)構(gòu)功能模型GreenLab進(jìn)行改進(jìn)，在提高擬合度的基礎(chǔ)上，獲得不同密度下番茄生長(zhǎng)參數(shù)，通過參數(shù)分析將環(huán)境與番茄植株生長(zhǎng)行為相聯(lián)系。結(jié)果表明密度影響同化物產(chǎn)生與分配，通過外在形態(tài)，如出葉速率、葉厚、坐果率等表現(xiàn)，GreenLab模型可以重建這種生長(zhǎng)行為變化。

    Abstract:

    In order to study the growth behavior of greenhouse tomato with different density, GreenLab, the functional-structural model, was improved. On the basis of improving the degree of fitting, the growth parameter of tomato with different density was obtained. Environment was connected with tomato plant growth behavior through the analysis of the parameter. The results show that the density influences production and distribution of assimilate, which was characterized by the exterior morpha such as leaf appearance rate, leaf thickness, fruit set rate and so on, and GreenLab model can reproduce this feedback relationship. 
