Abstract
在粘板岩／砂頁岩混合冲積土，土庫系壤質砂土，施用堆肥3000 kg/10a（於二月、十月各施50%）之情形下，二至四年生綠蘆筍（品種UC309），肥料三要素年施用量以氮素不超過30 kg/10a，磷肥及鉀肥不施爲經濟，磷、鉀肥用量增加對産量無明顯影響，甚至有減産趨勢。氮素（尿素）混合0.6 kg/10a AM硝化抑制劑(2-amino-4chlor-6-methyl pyrimidine)，平均可增産4.5-4.7%，但未達顯著平凖。
Results obtained from three years experiment with asparagus Variety UC 309, on a mixed slate and sandstone/shale alluvial soil, showed that the optimum rates of fertilizer under the conditions where 3,000 kg/l0 ares of manure was applied were 30 kg of N and 0~7.5 kg of P2O5 per 10 ares. Potassium was found to have no effect on the yield of green asparagus crop on this soil. The nitrification inhibitor AM (2-amino-4-chloro-6-methyl pyrimidine), when mixed with nitrogen fertilizer (urea), increased the yield by 4.5~4.7%. The analysis of the soil used in the experiment indicated that organic matter content was 0.98%, available K2O2 96 kg/ha and available P2O5 178 kg/ha.
