Abstract
經田間試驗探討芹菜、甘藍、大蒜、生薑之養分吸收經過及施肥效應，結果如下：
1.四種蔬菜作物主要無機要素吸收量如次。
2.芹菜和甘藍對各種無機養分之吸收以氮和鈣最多，鉀次之，磷較低。其施肥效應亦以氮和鉀較大，磷甚小。又酸性土壤施用石灰之效果最大。綜合各地試驗結果，芹菜和甘藍之三要素施肥適量N，P2O5，K2O各為225，90，150kg/ha和250~350，80，80~160kg/ha，可見施肥推薦量與養分吸收特性相當符合。
3.大蒜對各種無機養分之吸收以鉀和氮較多，鈣和磷較低。其施肥效應則以氮較大。據綜合各地試驗結果，其施肥適量為N，P2O5，K2O各100~200，30~60及50~100kg/ha。
4.生薑對各種無機要素的吸收以鉀最多，氮次之，鈣及磷均低。施肥效應亦以鉀肥最大。據綜合各地試驗結果，其N，P2O5，K2O施肥適量各為50~100，150~200，200~250kg/ha，可見其施肥推薦量和吸肥特性仍大致符合。
5.各種作物之生育及養分吸收經過如本文各圖。
Field experiments were conducted respectively on celery, cabbage, garlic and ginger, and the nutrient uptakes as well as the fertilizer responses were studied.
1. The amounts of major inorganic nutrients absorbed per crop by the four vegetables are respectively as follows;
2. Among the major inorganic nutrients, celery and cabbage absorb nitrogen and calcium the most, potassium the next, and phosphorus the least. The fertilizer responses also follow in similar order, and liming is particularly effective in acid soils. The optimum rates of N, P2O5 and K2O for celery and cabbage are 225, 90, 150 and 250-350, 80, 80-160 kg/ha, respectively, which are quite agreeable with the nutrient uptake character.
3. Among the major inorganic nutrients, garlic absorb potassium and nitrogen more, and calcium and phosphorus less. The fertilizer response is greater in nitrogen than in others. The optimum rates of N, P2O5 and K2O are 100-200, 30-60 and 50-100 kg/ha respectively.
4. Among the major inorganic nutrients ‘ginger absorb potassium the most, nitrogen the next, and calcium and phosphorus the least. The crop response to potassium is also the greatest. The rates of fertilizers recommended are 50-100, 150-200 and 200-250 kg/ha for N, P2O5 and K2O respectively, which is also quite corresponding to the nutrient uptake character.
5. The growth and nutrient uptake processes of the four vegetables are shown diagrammatically.
