Experiment for the duty of Water in paddy fields of New Variety Tongil (IR667)
신품종 통일 벼(IR667)의 용수량측정시험
Abstract
This experiment is conducted to see the alteration in calculation of amount of duty of water in paddy fields, by the miraculous rice TONG-IL(IR667) made its appearance to us, therefore results obtained were summarized as follow. 1. In comparison with depth of evapo-transpiration and evaporation in the evaporator, the ratio is ET/V=1.84 in clay loam and ET/V=2.00 in loam, the value is larger than any vairety. 2. Comparison by growing periods of rice plants growing period 5 and Ear for mation stage (primor stage) 6 ET/V value grow larger from 3.30 to 3.77. 3. Transpiration ratio is 260.4 in clay loam and 275.0 in loam, two value are less than 300.
기적의 법씨라 불리우는 통일(統一)(IR 667)의 출현(出現)으로 답용수량산출(畓用水量算出)에 변동(變動)이 생기지 않을까하여 본시험(本試驗)을 실시하였던바 다음과같은 사실(事實)을 알게되었다. (1) 엽수면증발량(葉水面蒸發量)과 증발계증발량(蒸發計蒸發量)의 비(比)는 식양토(埴壤土) ET/V=1.84, 양토(壤土) ET/V=2.00로 지금까지의 어느 품종(品種)보다 그 값이 컷다. (2) 생육기별(生育期別) ET/V를 볼 때 분약후기(分藥后期)와 유수형성기(幼穗形成期)에
