中文摘要 | 為探究適合高屏地區夏季栽培的蔬菜種類及生產模式,82~83二年在高雄縣旗南分場進行試驗,分別在簡易網室及露地兩種環境下比較20種蔬菜的適應性。結果葉菜類生育期間短,網室栽培生產穩定,產量及品質表現較佳。夏季網室葉菜之生育日數較露地約縮短2~5天,大部分在23~25天之間,產量最高達每公頃4~6 萬公斤,較露地平均約增加35%。尖葉萵苣、皺葉萵苣、芥藍、白菜、鳳山白菜等產量較高,青梗白菜、油菜(油菜心)、鳳山白菜、白菜(芳綠)等在風雨較少之夏季,採露地栽培每公頃仍有15,000公斤以上產量。網室蕹菜之表現與露地栽培者,差異不大。網室投資成本略高,但因產量較高,每公頃淨收益327,308元較露地增加1.3倍以上。成本中工資佔總成本78~80%,其中分級包裝約佔一半,連同間拔、除草、噴藥、採收等合計達90%,為今後進一步省工的重點。葉菜類遇連續兩星期豪雨,蕹菜、白莧菜耐濕性較強,損失輕微,萵苣、茼蒿稍具耐濕性,略有損失,網室較露地損失略輕。 |
英文摘要 | For testing the efficiencies of simple net house in order to grow summer leafy vegetables in Kaohsiung and Pingtung area, twenty different leafy vegetables were cultivated at the Chinan Branch Station of Kaohsiung DAIS. The experimental results showed that most of the leafy vegetables cultivated under simple net house were harvested within 23-25 days after sowing, about 2-5 days earlier than that cultivated in the open field. The average yield per unit area under simple net house was about 35% higher than that under open field. For some crops, such as leaf lettuce and rapeseed obtained more than 60 ton/ha under protection. For water convolvulus, however, cultivation under simple net house did not get yield increase. In fact, without severe storm damage, some leafy vegetables such as pak-choi and rapeseed can produce vegetable over 15 ton/her in the field. Based on the data collected from Fengshan Pai-Tsai, green petiole Pai-Tsai, white amaranth and leaf lettuce, the total production cost under simple net house was about 3%higher than that under open field, but their yield increase was about 45% higher than traditional cultivation, so the net income from net house production increased 130 % over the check treatment. Within the production cost, the labor cost occupied 78-80% of the total cost, in which half of the labor cost paid for grading and packaging expenses. Thus, it is worth while to work out a way to save labor cost for grading and packaging. Besides, after two weeks of continuous rain in August of 1994, we found most of the leafy vegetables were severely damaged in the traditional field, comparing with those leafy vegetables under simple net house, the degree of damages declined about 20%. For the two traditional summer leafy vegetables, water convolvulus and white amaranth, no injury wos found even in the open field. |
