中文摘要 | 本研究目的為探討在有機蔬菜/有機玉米輪作栽培下,施用有機肥料對作物生育及產量;以及對土壤pH值、電導度(EC)、有機質含量、Bray-1磷含量、交換性鉀、鈣及鎂含量等之影響,以期建立適用有機蔬菜栽培之合理施肥技術。試驗包括施用牛糞木屑堆肥20 t/ha及40 t/ha或有否施用有機液肥等4級處理,試驗Ⅰ為裡作有機球莖甘藍-春作有機玉米,試驗Ⅱ為裡作有機甘藍-春作有機玉米,試驗Ⅲ為裡作有機玉米-春作有機玉米。由試驗結果顯示,除試驗Ⅰ裡作有機球莖甘藍單位面積產量在不同有機肥料處理間達顯著差異水準,以牛糞木屑堆肥施用量40 t/ha處理高於20 t/ha處理;其它結果包括試驗Ⅰ春作、試驗Ⅱ及試驗Ⅲ兩期作之作物產量在各處理間差異均未達顯著水準。各試驗試區土壤pH值、EC值、有機質含量、Bray-1萃取性磷含量、交換性鉀、鈣及鎂含量均隨牛糞木屑堆肥用量增加而增加,各試驗春作有機玉米採收後土壤pH值、EC值、有機質含量、Bray-1萃取性磷含量、交換性鉀、鈣及鎂含量等相較於前期裡作有機蔬菜採收後,則有明顯下降情形。因此,在有機栽培不同期作分次適量施用堆肥,將是較合理且適用於有機蔬菜之施肥方式。 |
英文摘要 | In order to develop a suitable fertilization and rotation management for organic cultivation, an experiment was conducted to evaluate the effects of crops growth characteristics and soil fertility on the application of organic fertilizer in the rotation of organic vegetable and organic corn. The experiment was conducted with four organic fertilizer treatments and three rotations. Four organic fertilizer treatments included with cattle manure-sawdust compost in 20 t/ha or 40 t/ha amount, and applied with/without liquid fertilizer were conducted. In two season crop rotation treatments with I, II and III were kohlrabi/corn, cabbage/corn and corn/corn, respectively. The results indicated there were significantly different on the yield of organic kohlrabi among some organic fertilizer treatments in winter crop of rotation I. The yields of organic cabbage in winter crop of rotation II and organic corn in winter crop of rotation III, and the yields of organic corn in spring crop of rotation I, II and III were showed no differences among organic fertilizer treatments. The soil pH, EC, and the contents of organic matter, Bray-1 extracted P, exchangeable K, Ca and Mg increased according to the increasing of the application rate of cattle manure-sawdust compost. After harvesting of organic corn in spring crop of all rotation, the soil pH, EC, and the contents of organic matter, Bray-1 extracted P and exchangeable K, Ca and Mg decreased than that in winter crops have harvested. Therefore, rational dosage of compost application in the cultivation of different organic vegetable crops are proved to be reasonable. |
