研究了不同温度处理对温室番茄株系植株苗期生长的影响。结果表明,降温处理能显著降低温室番茄幼苗的鲜重、干重、株高、叶面积、叶片数和花序数;不同株系之间存在显著性差异;除鲜重与叶面积外,株系与温度处理对植株干重、株高、花序数与叶片数均没有互作效应;幼苗各生长时期的植株干重和相对生长率(RGR)与幼苗生长时间天数(t)可分别用一个二项式函数LnDW=a+b×t+c×t2与直线函数RGR=b+2×c×t(c≠0)来模拟。在此基础上,建立了温室番茄苗期生长TOSSIM模型。
The effects of different temperature treatments on the seedling growth of tomato plants in greenhouse were studied. The results showed that the cooling treatment could significantly reduce the fresh weight, dry weight, plant height, leaf area, number of leaves and inflorescence number of tomato seedlings in greenhouse. There were significant differences among different strains. In addition to fresh weight and leaf area, There was no interaction effect between temperature and treatment on plant dry weight, plant height, inflorescence number and leaf number. The dry weight and relative growth rate (RGR) and seedling growth time (t) The term function LnDW = a + b × t + c × t2 and the linear function RGR = b + 2 × c × t (c ≠ 0) are simulated. On this basis, the TOSSIM model of greenhouse tomato seedling growth was established.
