| 摘 要： | 为了探求新型稻渔共作模式对水稻生长及产量的影响,在宁夏回族自治区银川市贺兰县光明渔村开展了新型稻渔共作模式的实践。不同情况下稻田灌溉模式影响了水稻的生长以及产量。实验分为每隔5 d灌溉一次鱼塘水,每隔7 d灌溉一次鱼塘水以及不灌溉鱼塘水。水稻种植品种为“吉宏6号”,水稻平均亩产544.97kg,总体旱田亩产量高于水田,不同灌溉周期亩产量5 d灌溉一次>7 d灌溉一次>不灌溉鱼塘水。地上部分生物量旱田大于水田。灰色关联度分布为0.576～0.907。各水稻根茎秆构成因子与水稻产量关联度由强到弱排序依次为：根长（0.907）＞秆基部外径(0.863)=穗基部外径(0.863)＞秆长(0.846)＞株高(0.829)＞穗长(0.776),其中与水稻产量关联度最大的根茎秆构成因子是根长,关联度最小的是穗长;水稻产量构成因子与水稻产量关联度由强到弱排序依次为：有效穗数(0.869)＞穗粒数(0.847)＞生物量(0.813)＞结实率(0.806)＞千粒质量(0.759)＞每公顷穴数(0.715)＞根干质量（0.625）＞成穗率(0.576),其中与水稻产量关联度最大的产量构成因子是有效穗数,关联度最小的是成穗率。

| Abstract: | Abstract: In order to explore the significant effects of new rice-fish culture modes on rice growth and yield,the practice of a new rice-fishing culture model was carried out in Guangming Fishing Village, Helan County, Yinchuan City, Ningxia Hui Autonomous Region. Rice paddy irrigation patterns affect rice growth and yield under different conditions. The experiment divides the fish pond water once every 5 days, irrigates the fish pond water every 7 days and does not irrigate the fish pond water.Rice planting variety is "Jihong 6" The average yield per mu of rice is 1089.93/667m2 . The overall yield per mu is higher than that of paddy fields. The irrigation period is 5d for irrigation once > 7d for irrigation once > no irrigation of fish pond water. The upper part of the biomass is larger than the paddy field. There were different degrees of correlation between rice yield and yield components, and the overall correlation of gray correlation was between 0.576-0.907. the correlation between the root stem constituent factors and rice yield from strong to weak is: root length (0.907)> stem base outside diameter (0.863) = panicle base outside diameter (0.863)> stem length (0.846) > Plant height (0.829)> panicle length (0.776), the root stem constituent factor with the highest correlation with rice yield is root length, and the smallest correlation is the length of the stem; the correlation between rice yield component and rice yield is from strong to weak. The order of ordering is: effective panicle number (0.869)> grain number per ear (0.847)> biomass (0.813)> seed setting rate (0.806)> thousand grain weight (0.759)> hills per hectare (0.715)> root dry weight (0.625)> panicle setting rate (0.576), the yield component with the highest correlation with rice yield is the effective panicle number, and the smallest correlation is the panicle setting rate. |
