摘要:通過對編號為5251、6233、6721的3個黑西紅柿品種在常德職業技術學院農業產業園的引種栽培試驗,從生物規律、產量形成、產品品質等方面進行比較分析,結果表明,3個黑西紅柿品種生長態勢良好,抗病能力強,抗倒伏能力稍差,商品性好。研究可為黑西紅柿在常德的大面積種植提出栽培管理建議。

Abstract: By experiment on introduction and cultivation of three black tomato cultivars which were numbered as 5251, 6233 and 6721, respectively, in agricultural industry park of Changde Vocational Technical College, the comparative analysis was conducted among their biological habit, yield formation, product quality and other aspects. Results showed that three black tomato cultivars grew well, had strong disease resistance and good commodity value, and their lodging-resistance was a little weaker. It would put forward suggestions for cultivation and management of black tomato cultivars in the large-scale cultivation in Changde.

黑西紅柿為茄科(Solanum)番茄屬(Lycopersicon)的一個變種,一年生或二年生蔓性草本植物。其果型美觀,營養豐富,既是一種高檔蔬菜也是一種美味的水果,深受消費者的喜愛[1]。我國于2007年首次從美國引進黑西紅柿,在內蒙古巴彥淖爾市五原縣隆興昌鎮高效農業園區的大棚內試種成功。黑西紅柿試驗性種植的成功,意味著黑西紅柿的產業化繁育和推廣種植階段,為我國農業又增加了一張新名片。
1材料與方法
1.1試驗材料
種子為從美國引進的3個黑西紅柿品種,分別編號為5251、6233、6721。選取溫室內穴盤育苗法獲得品種幼苗,幼苗真葉6~7片。
1.2試驗地氣候條件與品種生物學特性
試驗在常德職業技術學院農業產業園進行。農業產業園位于常德市西郊,地處中亞熱帶向北亞熱帶過渡的季風濕潤氣候區,冷暖氣流交匯相對比較頻繁,特別是在春夏之交以及炎熱的夏季。年平均氣溫16.7 ℃,年降水量1 200~1 900 mm。黑西紅柿喜溫,其生長發育所需的溫度比普通西紅柿高,種子發芽的最適溫度為25~30 ℃。喜光,對光線比較敏感,光照不足時易徒長并落花落果嚴重,對水分要求前期少,后期多。……
