摘要
为研究在我国温室条件下番茄的生长发育规律 ,建立适应我国气候条件下的番茄生长模型 ,在山西太谷 (北纬 37°2 5″ ,东经 112°2 5″)山西农业大学设施农业工程研究所的温室内进行了番茄长季节栽培试验 (土壤栽培 ) ,所用品种为从荷兰引进的温室番茄专用品种Counter。结果表明在我国华北地区温室番茄长季节栽培能够成功。在试验条件下 ,番茄生育周期 2 5 2d时 ,茎长达 5 0 8cm ,叶数为 79.9片 ,花穗数是 2 2 .7。第一花穗以上的叶花比是 3.2。节间长 5～ 6cm。观察到的叶片出现率和花穗出现率相吻合 ,在春夏季分别是 0 .3971叶 /d和 0 .12 6 7花穗 /d ,即每 2 .5d长 1片叶 ,平均每 8d出现 1穗花。而在冬季 (11、12月 )是 0 .1138叶 /d和 0 .0 2 77花穗 /d ,即每 8.8d长 1片叶 ,平均每 36d出现 1穗花。
The long-season cultivation of the tomato in greenhouse was successful in north China. After 252 d growing the plant got stem length of 508 cm ,the number of leaves of 79.9 and the number of trusses of 22.7. The ratio between the number of leaves and the number of visible trusses was 3.2 above the first inflorescence. The stem length between two leaves was 5～6 cm.From spring to summer, leaf appearance rate and truss appearance rate was 0.3971 leaves/d and 0.1267 trusses/d meaning that a new leaf appeared every 2.5 days and a new truss every 8 days. But from autumn to winter, leaf and truss appearance rate was 0.1138 leaves/d and 0.0277 trusses/d respectively meaning a new leaf or a truss appeared every 8.8 days or 36 days.
