摘要

樹豆在臺東一般於每年2月－3月播種，12月開花、結莢，次年1月採收，但7月－10月為颱風好發期間，植株常遭遇侵襲而枯死。為避免因颱風侵襲而影響樹豆栽培及生產，降低天然災害發生。本試驗樹豆分別於6月、7月及8月播種，發現三種不同播種期植株仍可於12月開花、結莢，次年1月採收。顯示樹豆在7月－8月間播種仍有相當之莢果產量，不但降低因風災減少之損失，又可增加2月－6月間施予不同期作收益。

The pigeon pea are used to sown from February to March by the farmers of Taitung every year, and would flower and pod in December, be harvested in January of the following year. However, during the period of typhoon which is from July to October in Taitung, the peas of plants would often be attacked by the typhoon and died. In order to avoid the impacts of the cultivation and production of peas by typhoon attack, moreover, to reduce the occurrence of natural disasters and to decrease the losses of farmers. Therefore, this experiment postponed the peas' planting period of farmers in June, July and August respectively. After three years of experimental investigation, the three different sowing months were still flowering and pod-forming in December, and be harvested in January of the following year. It could be seen that there is a considerable pod yield during the planting period of pigeon pea in July-August. In addition, the farmers not only could reduce the loss by the typhoon disaster but also increase the income from different periods from February to June in the same field.
