Abstract
根據上述鳳山熱帶園藝試驗分所及臺灣省農業試驗所盆栽試驗結果，可歸納下列幾點結論：
1.福壽山土壤無肥盆栽試驗，鳳山與臺北兩試驗地之結果雖有出入，當初期生育情形比較，則屬一致，均呈萎縮難以生長狀態，而後期臺北試區之結果反較前者為佳；而在鳳山試區前後期均呈萎縮現象，可能臺北試區之四十日油菜耐酸性之能力較強之故。
2.兩地對照之園土無肥盆栽比較，雖生長並不十分理想，但無上述諸種缺點。由此可證明福壽山土壤不適蔬菜生長之主要原因，當在土壤中之酸度太高，而非氣候之關係。
3.福壽山土壤未種植前之pH測定為3.8－4.1，而鳳山土則為6.4，凡pH在4.0左右之高度強酸性土壤，一般作物實無法生育良好。
4.為謀改進此種強酸性土壤，乃進行有肥盆栽試驗，鳳山與臺北兩試驗地，加用適量腐熟堆肥及少量石炭，成效大增，鳳山試區經處理後之土壤產量增加60倍強，臺北試區則為5.5倍強。
Conclusions drawn from the pot experiments carried out in the Fengshan Tropical Horticultural Experiment Station and Taiwan Agricultural Research Institute, are as follows:
1. The growth condition of vegetables cultivated in the soil from Fushoushan both in Fengshan and Taipei in the early stages are mainly the same; the tendency to wilter in the later stages, it was observed those experimented in the Fengshan area remained the same, whereas those in the Taipei area turned out to be a little better. The anti-acid ability of Forty-day Rape used in Taipei may be accounted for the difference.
2. Comparisons made by using soil of the check control area without fertilizer application show, though not very satisfactory, no evidence of the abovesaid defects. It, therefore, proves that the main reason why the soil of Fushoushan is not fit for growing vegetables has nothing to do with climate, but because of the concentration of acidity.
3. pH in the soil of Fushoushan prior to being used in the experiments has been tasted as 3.8-4.1, while that in Fengshan is 6.4. It is generally understood that highly acid-concentrated soil with pH around 4.0 is unfavorable for plant growing.
4. In order to improve the highly acid-concentrated soil pot experiment is used again by adding a suitable amount of rotten compost and some lime in both Fengshan and Taipei. The results are promising. Production improvement of more than 60 times as much as before, and that of the Taipei area shows an improvement of 5.5 times.
