| 摘 要： | 不同灌溉方法下对水稻产量相关性状进行试验研究,结果表明:间歇灌溉地上部有效叶面积率、高效叶面积率均较高达到95.36%和81.34%,颖花数/有效叶面积、实粒数/有效叶面积、颖花数/高效叶面积、实粒数/高效叶面积高。且灌溉量与叶面积指数呈正相关,与粒/叶呈负相关。不同灌溉方式的产量构成差异不显著。 |

| Abstract: | The results of irrigating patterns showed that the above-ground effective leaf area rate and highly efficient leaf area rate reached 95.36% and 81.34%,respectively,when treated with intermittent irrigation,and the flowers/effective leaf area,grains/effective leaf area,flowers/highly efficient leaf area and grains/highly efficient were high.Irrigation amount was correlated positively with leaf area index,but negatively with grains/leaf area.The differences among yield components were not significant. |
| Keywords: | Rice Irrigation pattern Cold region Yield |
