摘要: This experiment uses Hogland and Shan Ch'i formula, respectively by the reagent level and the industry level raw material configuration, compared with it to influence pH value and the EC value change of culture solution, and influence to the growth in lettuce and pak-choi. Used Hoagland formula to culture lettuce and pak-choi, the daily pH value change is 0.08~0.66, in its average the climbing value and the climbing rate all significantly decrease 65% comparing the Shan Ch'i formula. The pH value of culture solution changes all to draw close significantly drops along with the cultivation number of days to is stable. Therefore its climbing rate significantly drops along with the cultivation number of days increase. The EC value of Hoagland formula is 1580~2080μS/cm, significantly higher than Shan Chi'i formula with 1015~1085μS/cm, and changes few during cultivation period. In leaf numbers, fresh weight, pH value of culture solution and the growth of lettuce and pak-choi, the use reagent level or the industry level raw material is not significantly. Therefore used Hoagland formula by the industry level raw material, the pH and the EC value compared the Shan Ch'i formula to be stable, and the growth of lettuce and pak-choi is better than Shan Ch'i formula, it is a worth reference for production.
本試驗採用Hoagland及山崎培養液配方,分別以試藥級及工業級原料配製養液,比較其對水耕養液之pH值及EC值變化之影響,及對尖葉萵苣與小白菜生育之影響。Hoagland配方養液栽培尖葉萵苣及小白菜,其每日pH值變化為0.08~0.66,其平均上升值及上升率皆顯著較山崎配方減少65%。養液中的pH值變化皆隨栽培天數之增加而趨近於穩定,故其上升率隨栽培天數的增加而明顯下降。Hoagland養液之EC值1580~2080μS/cm,明顯較山崎配方之1015~1085μS/cm為高,但栽培期間之變化少。Hoagland養液對尖葉萵苣及小白菜之葉片數、鮮重、葉面積等生育性狀顯著高於山崎氏配方。使用試藥級或工業級藥品配製養液,對養液pH值及植株生育性狀則沒有顯著差異。因此即便以工業級藥品配製Hoagland配方,仍可使養液pH值及EC值較山崎配方穩定,且對尖葉萵苣及小白菜之生育有明顯促進效果,值得生產業者參考使用。
