甘藍栽培試驗

（一）本試驗以甘攔宇治交配中生等十二品種，作一栽培比較試驗，期能選出一生長強健，產量豐富，葉球形體中等，開張性外葉較少之優良品種。（二）本試驗在台灣省立中興大學農學院園藝系蔬菜園進行。（三）本試驗採用隨機排例區組設計，三次重複，每小區長六公尺，寬一公尺，共三十六小區，每小區植二行，每行植十株，行株距均為60公分，於民國四十九年十月二十五日播種於苗床，同年十一月三十日定植於本園，民國五十年二月二十日至三月五日收獲調查完畢。（四）試驗結果1.結球重：以台灣早生及Succession之結球重量最大，以宇治交配中生及三季之結球重量最小。2.結球重佔全株重之百分率：以Succession及三池中生佔第一位，以宇治交配中生甘藍及增田交配黑葉中生甘藍佔次位，而以金門葉深廿藍及三季廿甘藍佔末位。3.株高，開張度及外葉數：以台灣早生佔第一位，宇治交配中生甘蘭及增田交配黑葉中生甘藍佔次位，以三季甘藍佔末位。4.結球率：以長岡交配一號及三池中生之結球率最大，以宇治交配中生甘藍結球率佔次位，而以台灣早生及三季甘藍之結球率最小。5.結球緊密程度：以長岡交配一號，宇治交配中生甘藍，及三池中生佔第一位，以三季甘藍及金門葉深甘藍之結球最為疏鬆。6.由上列各項結果比較之，以宇治交配中生甘藍為本試驗尋求之理響目標，共可成為一生長強健，產量豐富，葉球個體中等，開張性較小，外葉較少之優良品種，再配以稍密植方法種植，則可提高單位面積之產量。

l.Comparison of twelve cabbage varictie,with the objective of selecting a variety of good growth, higher yield, smaller plant, and moro compact head. This experiment was conducted in the vcgetable garden of the Depfortment of Horticulutre, Taiwan Provincial Chung Hsing University. 2.Adopting the random block arrangement design, this experiment consisted of 12 varieties, 3 blocks, 36 plots, each 6 m X lm with 20 cabbage seedlings. The cabbage seeds were sowed in the seedbed on Oct. 25, 1960, transplanted on Nov. 30 and harvested between Feb. 20 and March 5,1961. 3.The result indicated that the 11Yu-Chih cross medium maturing is a promising variety. The average head weight of 'Yu-Chih cross medium maturing' was 879g., the percentage of heading was 92.5% the percentage of head weight of the entire p1antnd wae 65.11% the size of whole plant was smaller than the others. 4.The average head weight of the other eleven varieties was larger and around l-1.5 kg. But the head was very loose. So the 'Yu-Chin cross medium maturing' is the variety of good growth, small plant with compact head. If we planted this variety close, we could obtain higher yield.
