Abstract
[Objective] The study was to select the celeriac variety that suitable for growing in north China. [Method]The main field characters of 15 celeriac germplasm resources selected by Beijing research center for vegetable were compared, and their characteristics, growth characters, cultivation technique etc were briefly introduced. [Result]15 celeriac germplasm resources all had coactus stem (before bolting), flat and sector leaf with smooth leaf surface ( without bristle) and deep sawtooth at leaf margin etc. The individual of celeriac varieties 7010056, 7010059 and 7010099 were small, and the single root weight of other varieties was 200-400 g. The comprehensive characters of 7010197, 7010061, 7010096 and 7010100 were good, so they were suitable for growing in north China. The suitable colonization density of middle early varieties was 75 000-90 000 plants/hm~2, and that of late varieties was 60 000 plants/hm~2, and water and fertilizer management should be strengthened after seedling recovering. The suitable temperature for celeriac in its root-expansion process was 15-20 ℃ in daytime, and 5～8 ℃ at night. [Conclusion]Celeriac varieties 7010197, 7010061, 7010096 and 7010100 were suitable for growing in north China.关键词
