中文摘要 | 本研究目的擬探討使用雞糞堆肥、牛糞堆肥及豆粕液肥等不同有機肥料種類及用量,對有機葉菜類氮、磷及鉀養分吸收特性之影響效應。試驗處理包括施用雞糞堆肥10 t/ha、雞糞堆肥20 t/ha、牛糞堆肥10 t/ha、雞糞堆肥10 t/ha 配合豆粕液肥20 l/ha、牛糞堆肥10 t/ha 配合豆粕液肥20 l/ha、空白對照處理等七級處理。試驗第一作為有機白莧菜,第二作為有機青江菜。由試驗結果顯示,有機白莧菜及有機青江菜的氮、磷及鉀吸收量均以施用雞糞堆肥10 t/ha配合豆粕液肥20 l/ha處理較高,有機白莧菜採收期地上部植株氮、磷、鉀吸收量比例約為5:1:8,有機青江菜約為6:1:9。有機白莧菜生育後期的氮、磷、鉀的吸收速率約為生育前期之3倍強,有機青江菜生育後期的氮、磷、鉀的吸收速率約為生育前期之4倍強,顯然有機葉菜類生育後期必須吸收足量的肥料養分,以供應生長需求。因此,施用適量的雞糞堆肥與豆粕液肥較能夠配合有機葉菜類的養分吸收特性。 |
英文摘要 | The objective of this research was to evaluate the effects of the N, P and K uptake characteristics of organic leaf vegetables on the application of different kinds and rates of organic fertilizers. Field experiment was conducted with seven treatments, including chicken waste compost 10 t/ha, chicken waste compost 20 t/ha, dairy waste compost 10 t/ha, dairy waste compost 20 t/ha, chicken waste compost 10 t/ha + liquid soybean fertilizer 20 l/ha, dairy waste compost 10 t/ha + liquid soybean fertilizer 20 l/ha and blank, on the cultivation of organic Chinese spinach (Amarath mangostanus L.) and organic Pak-choi (Brassica campestris L. Chinensis Group). The results indicated that the N, P and K uptake amounts of the shoot of organic Chinese spinach and organic Pak-choi on the application of chicken waste compost 10 t/ha + liquid soybean fertilizer 20 l/ha had the best response. The ratio of N, P and K uptake amounts of the shoot of organic Chinese spinach and organic Pak-choi at harvest stage were 5:1:8 and 6:1:9, respectively. The N, P, and K uptake rates of the shoot of organic Chinese spinach at later growth stage were more 3 times higher than that at early growth stage. The N, P, and K uptake rates of the shoot of organic Pak-choi at later growth stage were more 4 times higher than that at early growth stage. The results indicated that the nutrients uptake at later growth stage should be enough to support the growth of organic leaf vegetable. Therefore, the application of chicken waste compost with liquid soybean fertilizer is a suitable fertilization for the nutrients uptake characteristics of organic leaf vegetable. |
