中文摘要 | 澎湖地區生產夏季蔬菜之主要限制因子為溫度高、日照太強及土壤有機質含量偏低。為改善夏季蔬菜生產,本試驗以40%,50%,60%,70%等黑色遮光網處理,並分別施用0.25,0.50,0.75,1.00m3之樹皮堆肥,探討對澎湖地區夏季小白菜、空心菜、結球白菜、青花菜、花椰菜等生長之效果。試驗結果,樹皮堆肥量對小白菜,空心菜等短期葉菜類之產量分為三個等級,以全樹皮堆肥處理者表現最佳,其次為添加0.25-0.75m 3 處理者,生長最差者為本地土壤。隧道棚或水平棚架等簡易設施上,覆蓋40-50%遮陰程度之遮光網,對小白菜、空心菜、青花菜(綠王)及花椰菜(鳳山極早生)之株高有明顯促進之效果,產量也增加,但對耐熱性佳之結球白菜(亞蔬一號)之反應則相反,不遮蔭處理者反比遮蔭處理者為佳,顯示遮蔭處理之效果會因蔬菜品種之特性而有差異。 |
英文摘要 | High temperature, strong sunshine and low organic matter in the soil are the limmit factors to produce summer vegetables in Penghu. In order to improve the production of summer vegetables, five common vegetables were used for experiments, including pak-choi,water convolvulus, chinese cabbage,cauliflower and broccoli. These vegetables were planted in the field of Penghu substation,Kaohsiung DAIS from 1993 to 1994. The main purposes of these experiments were to identify the effects of shading and bark compost application. Four different levels of shading, namely, 40%, 50%, 60%, and 70% of sunshine, were arranged, and non-shading was used as check treatment. The results showed that the tretments with 40% or 50% of shading obtained a positive effects on plant growth and yield for pak-choi and water convolvulus . For chinese cabbage and cauliflower, however, the shading effects on yield was not signifcant difference. For studing the effects of bark compost application, four different treatments were designed, including 1.00, 0.75, 0.50 and 0.25m 3 of bark compost were applied respectively. The treatment with no bark compost application was served as the control. The experimental results indicated that all the treatments of bark compost application were effective for plant growth and yield of pak-choi; but for water convolvulus, only the treatment with 1.00m^3 of bark compost application obtained higher yield than that of the control. |
