摘要

以甘藍初秋及結球白菜綠陽品種為供試材料，進行不同苗齡移植苗對育苗品質及田間產量影響試驗，甘藍、結球白菜分別以苗齡3－10週及10－60天及直播等處理。甘藍及結球白菜穴盤苗的葉數、葉面積、株高、株重等隨著苗齡增加而增加，土播苗亦有相同趨勢，但甘藍及結球白菜穴盤苗的根長分別在苗齡7週及35天達到最高後呈下降趨勢，土播苗則隨著苗齡增加而增加。甘藍穴盤苗壯苗指數介於0.06－0.20，其中苗齡5－8週處理無顯著差異。甘藍土播苗亦有相同趨勢。甘藍不同苗齡穴盤苗的球重無顯著差異，因此苗齡不會影響球重，而產量有差異存在的原因主要是成活率所造成，土播苗不同苗齡間有顯著差異存在。結球白菜種植穴盤苗在球莖高X寬及葉球重以直播及苗齡35天較差外其餘苗齡間差異不顯著。苗齡對結球白菜僅造成生育日數明顯縮短。產量與移植苗品質性狀相關性分析中，甘藍土播苗性狀與產量呈不顯著負相關，但甘藍穴盤苗的莖粗及葉片數與葉球重呈顯著負相關（-0.77*、-0.77*）。在結球白菜穴盤苗性狀與產量呈不明顯正相關。

The experiment used vegetable transplant age to compare the quality and yield in cabbage (K-Y cross) and Chinese cabbage (Green-Sun). The treatment used 3-7 weeks and 10-60 days transplant age in cabbage and Chinese cabbage. The results were following.The older transplant age cabbage and Chinese cabbage had the same larger in the numbers and sizes of leaves, taller in the plant height and the heavier in the plant weight. The seedling index of cabbage in plug seedling is ranging from 0.06 to 0.20. However, there is no significant difference from the 5th through the 8th week. And the cabbage tradition seedling there was same result. The results of field experiment indicated that there was no significant difference among the different transplant age of the plug seedling in the head weight, etc. And there is also significant difference in the yield depend on survival percentage. There was significant difference by tradition seedling age in yield. However, the performance was better in head weight from the 3rd through the 7th week. And the difference in yield is mainly because of the different of survival rate. There were lower performances in the height x width and head weight all the direct seedling and 35-day transplant age. And there was a significant shortening the growing stage of time in Chinese cabbage. The correlation coefficient between the yield and quality characters of seedling showed that there were significant and negative correlation (-0.77*, -0.77*) between the diameters of stems, numbers of leaves and the head weight of cabbage plug seedling. Whilst, there was no significant correlation existed between the tradition seedling cabbage and Chinese cabbage.
