98期中考 2.Define the following terms used in olericulture:(6+12%) (1)harvest index 計算生產效率(Economic yield/Biological yield) (2)vernalization 春化作用,使seed germination or fruit & flower development (3)nitche market or specialty vegetables 特別的品種? (4)head formation ? and the use of the following terms: (5)heat unit 積溫 ,用來計算果實成熟的時機 (6)light saturation point 光飽和點,決定植物對光的需求 (7)critical growth period ? (8)mulch 以覆蓋物蓋上土壤,防止雜草生長 (9)liming 灑石灰調整pH值 (10)fertigation 施肥,提供養分 (11)fertilizer analysis 分析肥料的內容以調整所需施用量 (12)starter solution ? 4.What eare the differences between:(20%) (1)cool season vegetable crops VS warm season vegetable crops ability of young plant to with satnd frost seed to germinate at low temp (2)determinate type of growth VS indeterminate plant growth --both domintant vegetative & reproductive phase --domintant vegetative phase and equal balance of vegetative & reproductive (3)market gardening VS truck farming --多種類,量少,離市場近 --集約,量大,較遠 (4)vegetable production for processing VS vegetable production for fresh use --plant 外表較不注重,較注重taste --除了taste外還有外表以及保存能力,可能須冷藏等保存方式 (5)Open pollinated cultivar VS F1 hybrid cultivar   --在田間作nature pollinated,數量較大,但品質不易控制 --品質一致,且F2的品質不如F1,有助品種保護,但比較貴,數量也較少   (6)rotation crop VS cover crop --輪作的作物,為主要的product --在輪作期間用以增加土壤肥沃度的作物,綠肥 (7)Sprinkle irrigation VS drip irrigation --噴灌,較省時省力,但浪費資源 --滴灌,節省水資源很有效,但裝置設置較麻煩也比較貴 5.What do you know about vegetable industry or production in Taiwan? And the trend of vegetables consumption?(5+5%) 大部分都內銷,然後集中於中部 經濟稍微復甦後蔬菜消費量提高 6.What are the benefits of controlled-environment production of vegetables? and what are the common use of plant growth substances in vegetables? (5+4%) 可以周年生產,也可用於最佳化生產,史作物有最適合的環境生長 生長素,吉貝素,細胞分裂素,離層酸,乙烯 7.Why crops grown at optimum temperature will yield better?(5%) How light affects the vegetable plant growth and development? (5%) How do we know plant water requirement? What about cucurbits water requirement (4%) What are the purposes and the practices of field tillage?(5%) 在optimum temp 可以使作物的生理反應效率達到最高,所以產量提高 光合作用影響植物合成養分,光周期則影響植物的development ??? 使土質鬆軟利於根系發展,將深層的養分帶上淺層 8.Why the vegetable are transplanted? How does the cell size of the plug tray affect the seedling growth and vegetable production?(8%) 可提高高經濟作物的存活率 忘了 --- 請給分XDD -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.4.196
