本試驗於嘉義農業試驗分所水源地進行，種植馬鈴薯前後進行土壤分析，結果顯示種植前後土壤均屬中鹼性，種植前有效性磷及鉀肥力含量甚低；以台農1號及克尼伯品種的馬鈴薯，分別以健康種薯及普通種薯為材料，10 cm及20 cm稻草敷蓋畦面處理，試驗結果顯示採敷蓋稻草的栽培方式，採收塊莖後土壤的有效性磷、交換性鉀含量及有機質含量皆較種植前增加。台農1號及克尼伯品種採用健康種薯的出苗率最高分別達85.7%及92.6%，兩品種種植健康種薯的株高顯著高於普通種薯，而兩品種皆以敷蓋10 cm稻草者的產量高於敷蓋20 cm稻草的處理；且除小薯的產量外，選用健康種薯栽培者大薯及中薯的產量，皆比選用普通種薯栽培者高33～53%，台農1號不論選用健康種薯或普通種薯種植，產量皆高於克尼伯品種。本試驗結果可供利用健康種薯及未來發展稻稈鋪設機敷蓋稻草厚度之參考。
The research was conducted at farm in Chiayi Agricultural Experiment Station. The soil of the study was carefully analyzed before the experiment, and the results showed that there was no difference of pH level before cultivation and after gathering of potatoes. Besides, the content of available phosphorus and potassium were very low before cultivation. In this experiment, we used virus-free seed tuber and seed tuber of Tainung No. 1 and Kennebec potato varieties for experimental materials with 10 cm or 20 cm straw mulching on the top. The results showed that validity phosphorus, exchangeable potassium and the organic matter content increased while potatoes grew under mulching straw on the top after the experiment. The germination rate of Tainung No. 1 and Kennebec potato could reach to 85.7 % and 92.6 % separately by using virus-free seed tuber, and it had higher plant height than those of using seed tuber. It also showed that two potato varieties treated with 10 cm mulching straw would obtain the highest tuber yield. At the same time, using virus-free seed tuber potato was able to get higher tuber yield 33 % to 53 % no matter what kind of seed tuber the middle size or the lager size, was used. For both virus-free seed tuber and seed tuber, Tainung No. 1 potato could get higher tuber yield than the Kennebec. The outcome of this entire experiment could be a reference on the future studies on virus-free seed tuber and straw coverage.
