摘要： 为探讨穗直立程度不同的水稻品种茎秆不同部位伤流强度的差异，在田间条件下选用穗直立程度不同的3个水稻品种沈农265、豫粳6号和水晶3号，系统研究了基部节间、中间茎节和穗颈节间伤流强度的动态变化。结果表明：（1）同一穗型水稻品种不同部位的伤流强度随生育期的变化有很大差异，以基部节间伤流强度最大,其次为中间茎节，穗茎节伤流强度最小；（2）不同穗型的水稻品种基部节间、中间茎节、穗颈节的伤流强度变化趋势基本一致，其总体趋势是下降的；（3）弯曲穗型的水稻品种不同部位伤流强度一般要比直立穗型的高。

Abstract: The bleeding intensity at the different part of paddy rice with different-type was studied by using the varieties of Shennong 265, YuJing No.6 and Shuijing No.3 at the field experiments. The results indicated that: (1) the bleeding intensity has very big difference in different part during the growth periods of the rice species of the same Panicle-Type. (2) The trend of the bleeding intensity in different part of the paddy rice species is consistence, and its total trend is descendent. (3) The bleeding intensity in each part of the paddy rice species of the bent Panicle-Type is higher when comparing the erection Panicle-Type.
