Effect of Cytozyme Enzyme Complexes on Rice Yield

수도(水稻)에 대(對)한 Cytozyme 처리효과(處理效果)

The effects of two Cytozyme complexes, Crop Plus and Seed Plus, applied to rice (variety: Jinheung) were evaluated during the 1980 rice growing season. Primary objectives were directed to determine the effects of rates, timing and method of application of the products on the yield of rice. For the Seed Plus test, seed was soaked in the diluted Seed Plus solution(1 : 100) for 24 hours just prior to sowing. The Crop Plus was diluted to 1 : 12 for seedling treatment. Seedling roots were immersed in the diluted solution for 3 hours before transplanting. Crop Plus spray applied at the rates of 450ml/ha or 900ml/ha when rice plants were in the panicle initiation, heading or tillering stage respectively to compare the effects of rates and timing of application. The weather was not favorable for rice growth during the growing season except the tillering stage. The foliar spray at the tillering stage was more effective than the spray at the panicle initiation, and the rates of 900ml/ha showed better results than 450ml/ha. Combination of seed treatment and foliar spray increased grain yield by 16% over untreated control plots.

Biological support products로서 알려진 효소복합제(酵素複合劑)인 Cytozyme이 한국(韓國)의 재배환경조건(栽培環境條件)에서 수도수량(水稻收量)에 미치는 효과를 검토(檢討)하였다. 진흥품종(振興品種)을 사용(使用)하여 강서사양토(江西砂壤土)(Fluvaquentic Eutrochrepts)의 서울대학교(大學校) 농과대학(農科大學) 답작포장(畓作圃場)에서 Seed Plus Cytozyme 종자침지(種子浸漬), Crop Plus Cytozyme 묘근침지(苗根浸漬), 생육기별(生育期別), 농도별(濃度別), Crop Plus 엽면살포(葉面撒布) 등의 효과를 분석(分析)하였다. 1980년(年)의 불리(不利)한 기상조건(氣象條件) 및 병발생(病發生)으로 반복간(反覆間) 변이(變異)가 심(甚)하여 처리간(處理間)에서 통계적(統計的)인 유의성(有意性)은 없었으나 엽면살포(葉面撒布)는 유수형성기(幼穗形成期), 출수기(出穗期)보다는 분벽기(分蘗期)에, 처리수준(處理水準)에서는 450ml/ha보다는 900ml/ha 처리(處理)하는 것이 증수(增收)되는 영향이었다. 종자침적(種子浸漬) 및 엽면살포(葉面撒布)의 이중처리(二重處理)한 효과가 가장 높았으며 무처리구(無處理區)에 비(比)하여 16%의 증수(增收)를 나타내었다.
