摘要

本試驗於民國47年第一期作開始，在龍潭、新埔等兩試驗地進行。然後逐年增加，楊梅、大溪鎮及平鎮鄉等試驗地舉行試驗。目的爲尋求看天田適用抗旱新稻種及其耕腫拾施以供今後看天田稻作改良之參考。
本報告係自民國47年第一期作至民國50平第二期作計四個年間之試驗結果。簡列如次：
(1)歷年來於北部看天田，舉行試驗結果，在試驗期間巾均遭受嚴重缺水抗制情形下，其平均產量臺農2號爲最高，臺農1號次之，在來蟻公包再次之，水稻臺中65號爲最低。其四個年平均產量如下：
(表格略)
(2)在各試驗地，就稻作生育情形觀之，對照品種臺中65號及在來蟻公包，受較輕微之乾旱，生育上也立即受阻變成矮黃，惟臺農1號及臺農2號受較嚴重缺水抗制情形下並無發現矮黃及旱死之跡象，此可證明新品種的抗早能力。
(3)爲期看天田低產地區的稻作增產，除加緊研究選育抗旱品種外，將施肥耕腫措施及害翁防治等，尚待深入研究改良。

This experiment began from the first Crop at Luong-tang and Hsin-puh in 1958, Other experimental grounds were establishes at Yang-mei, Ta-chi and Ping-ching year by yeart The purpose was to seek out adaptable drought-resisting Crops seeds and new ways of Cultivation for weather depending Paddies.
This report is a result of four-year experiments from the first crop in 1958 to the second crop in 1961.
(1) Experiment node on the northen Taiwan, under serious water-locking Conditiun shoud Tailong No. 2 had the highest yield, Tailong No. 1 the Second, Y(The symbol is abbreviated)kung puo the third, and Taichung No. 65 the lowest. The four years avarage yield was as follows.
(The form is abbreviated)
(2) according to the growth Condition checking Varietie Taichung No. 65 and Yikung pзo had been slighily affected by drought and was immedietely farred brom growth became short and yellow. Whereas drought Tailoung No. 1 and Tailoung No. 2 under much more Serious water-locking condition No. symptams of shortering yellowish ness and death. The abare it is believable than the later ones are more apt to resist drought.
(.3) In order to promote the yieldability in the low-yield weather depending paddy-fields, it is necessary to straighten the studie on selecting drought-resisting varieties, Impromement must olso be suggested on the fertiliting and cultivation.
