冷水灌漑 및 晩植時의 水稻登熟에 미치는 燐酸과 窒素의 相互作用

安壽奉 충남대학교 농업과학연구소 1980 農業技術硏究報告 Vol.7 No.1

In order to find the interaction between phosphorus and nitrogen effects during low temperature treatment, experiments of rice planted late at low water temperature were conducted and the following results were obtained. As the application of phosphorus increased, the soluble nitrogen content in the rice plants was decreased, while the degree of ripening was improved, especially when the application of nitrogen increased. When the heading was promoted due to high temperature, degree of ripening was improved. The number of spikelets increased due to the increased application of nitrogen fertilizers, and then The effects of phosphorus application on the improvement of ripening was less apparent.

수도(水稻)의 물질생산(物質生産)과 그 구조(構造)에 관(關)한 연구(硏究) I. 수도개체군(水稻個體群)의 생장속도(生長速度)와 생산구조(生産構造)

수도개체군(手稻個體群)의 생장(生長)과 수량(收量)을 생산생태자적관점(生産生態字的觀点)에서 해석(解析)하고저 그 생산구조(生産構造)와 평균생장속도(平均生長速度) 및 관련요인(關聯要因)의 영향(影響)을 구명(究明)하여 다음과 같은 결과(結果)를 얻었다. 1. 개체군하(個體群下)에서는 개체상태(個體狀態)보다 전생육기간(全生育期間)에 걸쳐 높은 평균생장속도(平均生長速度)를 지속(持續)하였으며 등숙기간(登熟期間)의 생장속도(生長速度)가 비교적(比較的) 높아 수량(收量)이 증가(增加) 하였다. 2. 벼의 개체군(個體群)이 평균생장속도(平均生長速度)를 높게 유지(維持)하였음은 순동화율(純同化率)보다 엽면적증대(葉面積增大)의 영향(影響)이 더 컸었다. 3. 개체군(個體群)서 품종(品種)에 따라서는 상위엽층(上位葉層)의 과번무(過繁茂)로 하위층엽(下位層葉)에 대(對)한 투광(透光)를 저해(沮害)하여 그 고사(枯死)를 많게 하였다. 4. 개체군(個體群)에서는 생육후기(生育後期)에 갈수록 동화기관(同化器官) 대(對) 비동화기관(非同化器官)의 비율(比率), 투광율(透光率) 및 엽신(葉身)의 질소함량(窒素含量)이 상대적(相對的)으로 저하(低下)하였다. In order to analyze growth and yield of rice population at the stand point of productive ecology, productive structure and growth rate of rice plants and effects of their related factors were studied. The results obtained were summarized as follows: 1. High crop growth rate was maintained throughout growing season when rice plants grew in population compared to a single rice plant. Since crop growth rate in rice stands were also higher at ripening stage, higher yields were obtained. 2. Higher crop growth rate of rice plants in population was maintained by the increase of leaf area rather than by net assimilation rate. 3. As the overgrowth of upper leaves of plant population in some rice varieties transmission of light into lower leaves was inhibited and thus most of them were eventually died before flowering. 4. In the case of rice population, the ratio of productive organ to non-productive organ, light transmission rate and nitrogen contents of active leaf blade were lower than individual rice plants under isolated condition.

수도준계이앙용(水稻俊械移秧用) 상자육묘(箱子育苗)에 있어서 파종밀도(播種密度)와 육묘기간(育苗期間)이 묘(苗)의 생장(生長)과 소질(素質)에 미치는 영향(影響)을 분석(分析)한 바 상자당(箱子當) 파종량(播種量)이 많을수록 묘당업면적(苗當業面積)과 평균생장속도(平均生長速度) 및 안면적비(案面積比)는 감소(減少)하고 엽령(葉令), 초장(草長), 묘당건물중(苗當乾物重) 및 건물중대초장비(乾物重對草長比)가 적어지고 제(第)1 엽초장대초장비는 커지는 경향(傾向)이었고 지나친 밀파(密播)는 엽신(葉身)의 과도(過度)한 신장(伸長)을, 그리고 심(甚)한 밀파(密播)는 묘(苗)의 연약화(軟弱化)를 초래(招來)하므로 기계이앙재배(機械移秧栽培)에 알맞은 파종밀도(播種密度)는 25일묘(日苗)에는 상자당(箱子當) 150g내외(內外), 그리고 30일묘(日苗)에서는 100-150g 범위(範圍)로 보인다. 한편(便) 육묘일수(育苗日數)는 많아질수록 묘당엽면적(苗當葉面積)은 커지나 순동화율(純同化率)이 이에 따르지 못하여 평균생장속도(平均生長速度)는 파종후(播種後) 30일(日)에서 35일간(日間)에 최고(最高)에 달(達)하고 업령(業令), 혁장(革長), 건물중(乾物重) 및 건물중대초장비(乾物重對草長比)도 適當하였으나 파종(播種) 35일(日) 이후(以後)에는 엽령(葉令)의 진전(進展)과 건물중증가(乾物重增加)는 거의 정체(停滯)하였고 묘(苗)가 노숙화(老熟化)되므로 30일(日) 정도(程度)가 기계이앙(機械移秧)에 알맞았다. Effect of the seeding rate and nursery period on the growth and characteristics of seedling suitable for rice transplanter was analyzed and the following results were obtained. The optimum seeding rate were about 100 to 150g in the 30 day old seedling, and 150g per nursery box in the 25day old seedling, respectively, as having adequate leaf number, plant height, dry weight, hardiness and crop growth rate for transplanting. Excessively low and high seeding rate resulted in excessive aging and weakness of the seedling at the later growth stages.

추락답(秋落沓)에 있어서 석회(石灰)와 생고시용(生藁施用)이 담수하(湛水下)의 토양(土壤)pH와 수도(水稻)의 양분흡수(養分吸收), 생육(生育) 및 수량(收量)에 미치는 효과(效果)와 그 잔효(殘效)를 구명(究明)코저 시험(試驗)한바 그 결과(結果)를 요약(要約)하면 다음과 같다. 소석회생고병용시에는 금비단용(金肥單用)에 비(比)하여 평균(平均) 41%의 가리효과(增收效果)가 인정(認定)되었다. 소석회(消石灰), 생고병용시에는 수도(水稻)의 생육(生育) 후기(後期)에 하엽고사(下葉枯死)가 적었으며 생육(生育)이 왕성(旺盛)하고 호마엽고병(胡麻葉枯病)과 도열병피해(稻熱病被害)가 극(極)히 경미(輕微)하였고 수당입수(穗當粒數), 등열비율(登熱比率) 및 입중(粒重)이 모두 대조구(對照區)보다 월등(越等)히 많고 높았다. 소석회생고병용시에 수도(水稻)는 더 많은 규산(珪酸), 석회(石灰), 질소(窒素) 및 가리(加里)를 흡수(吸收)하였다. 소석회(消石灰)와 생고시용(生藁施用)의 잔효(殘效) 매년(每年) 반감(半減)되고 1년차(年次) 20%, 2년차(年次) 10%, 3년차(年次) 5% 정도(程度)이였다. 논토양(土壤)의 pH는 소석회(消石灰)와 생고(生藁)에 다같이 영향(影響) 받으며 처리후(處理後) 약(約)8일후(日後)에 일정치(一定値)로 고정(固定)되였으며 0.3%의 소석회하(消石灰下) 생고다시용시(生藁多施用時)에는 생고무시용시(生藁無施用時)보다 pH 값은 떨어졌다. 담수하(湛水下) 논토양(土壤)의 pH는 소석회(消石灰) 및 생고시용량(生藁施用量)과 다음과 같은 함수관계(函數關係)를 나타내였다. $$pH=5.5293+8.6007X_1+2.7836X_2-{6.7422X_1}^2-{1.8522X_2}^2-7.000X_1X_2$$ ($X_1$=소석회(消石灰), $X_2$=생고(生藁)) This study was conducted to determine the effect of slaked lime and straw used on the soil pH in the flooded condition and yield of rice grown in AKIOCHI paddy field and their residual effects on the rice plants. The results obtained were summarized as follow: when lime and straw were applied, there was on the average 41% of yield increase over plots treated with three elements of chemical fertilizers. When lime plus straw were used, the growth rate at later stage of rice plant was prominent. Damage due to helminthosporium and blast were found less, the rate of lower-leaf death was low, and grain number, per head, filled grain ratio, and weight of rice grain were higher than control. When lime plus straw were used, higher amount of silicate, calcium, nitrogen and potassium was found in the plants at heading stage. The residual effects of lime plus straw were 20% in the first year, about 10% in the second year and 5% in the third year, respectively. Soil pH was affected by both straw and slaked lime, and it was fixed about 8 days after applying in the flooded condition. The following formulae was suggested from the results in the flooded conditions. $$pH=5.5293+8.6007X_1+2.7836X_2-{6.7422X_1}^2-{1.8522X_2}^2-7.000X_1X_2$$ ($X_1$=slaked lime, $X_2$=straw)
