[目的]探究华北地区日光温室番茄生长发育及物质生产分配规律。[方法]以番茄品种＂金果1号＂为试验材料,于2014、2015年3月至7月在山西太谷（北纬37°25′,东经112°25′）山西农业大学日光温室内进行了两年的番茄春夏茬栽培试验。[结果]日光温室番茄株高、叶数、叶面积以及干物质生长量均与定植后的生长天数呈显著线性关系,其相应生长规律分别为2.74 cm/d,0.32片/d,70 cm~2/d,9.4 g/（m~2·d）;果实干重与植株总干重之间呈线性关系,坐果后植株总干重每增加1 g,果实干重约增加0.69 g;干物质在根、茎、叶中的分配比例从开花前到坐果后呈显著下降趋势,果实干重在植株总干重中所占比例显著增加,达到60%以上。同时,番茄干物质生产量与温室有效积温（〉10℃的温度总和）之间有很强的线性关系,每个有效积温单位（°C·d）,干物质的生产量约为0.73 g/m~2;植株干物质生产与太阳辐射量之间也有较强线性关系,每个光合有效辐射单位（MJ）大约生产3.4 g干物质。[结论]适当延长番茄生育期,改善温、光条件即可提高番茄的物质生产量。

[Objective] This study aimed to investigate the growth and development and dry matter production and allocation of greenhouse tomato in North China. [Method] With tomato cultivar ＇Jinguo No.l＇ as the experimental material, the ex- periments were conducted in a solar greenhouse located in Taigu, Shanxi （37o25＇ N, 112o25＇ E） from March to July, in 2014 and 2015. [Result] The plant height, leaf number, leaf area and dry matter production of greenhouse tomato increased lin- early with the increased days after transplantation, and their growth rates were 2.74 cm/d, 0.32 leaf/d, 70 cm2/d and 9.4 g/（m2.d）, respectively. The fruit dry weight also showed a linear relationship with the plant dry weight. After fruit setting, the fruit dry weight was increased by about 0.69 g when the plant dry weight was increased by 1 g. The allocation proportions of dry matter in tomato roots, stems and leaves de- clined significantly from plant flowering to fruiting, while the proportion of fruit dry weight in plant dry weight increased significantly, exceeding 60%. There was a strong linear relationship between dry matter production of tomato and effective cu- mulative temperature （sum of temperature higher than 10 ~（3） in the solar green- house, and the dry matter production was increased by about 0.73 g/m2 when the effective cumulative temperature was increased by one unit. The dry matter produc- tion of tomato plant also showed a strong linear relationship with photosynthetic ac- tive radiation （PAR） in the greenhouse, and about 3.4 g of dry matter was synthe- sized per unit （M J） of PAR. [Conclusion] Extending the growing period and improv- ing the temperature and light conditions could increase the dry matter production of tomato.
