| 摘 要： | １９９７－１９９８年研究了砂姜黑土区不同叶枝留量对棉花产量的影响，结果表明，留叶枝与常规整枝相比单株成铃增多，铃重大，成铃时空分布合理，烂铃减少，优质铃增加，但不同叶枝留量效果不同，Ｔ４效果最好，皮棉增产３１．５％，霜前花率提高１６．６％。 |

| Abstract: | The influence of different leaf branches remained on yield of cotton were studied in Shajiang black soil from 1997 to 1998.The results showed:boll settings per plant were increased and the boll weight enhanced;a more reasonable time and space distribution of boll setting,a decreased number of cotton bolls and an increased number of good bolls were observed.However,different effects were found in different leaf branches remained.Among all the combinations,T 4 was the best whose lint yield was increased by 31.5%,and the rate of prefrost lint yield heightened by 16.6% . |
