摘要
对 1 997～ 1 998年各位棉铃发育期内所获温度值和有效辐射量的实际测定值的分析知 ,棉铃发育所需≥ 1 5℃有效积温范围为 534～ 70 0℃ ,有效辐射量范围为 62 0～ 4 0 0 0mmol·dm-2 ·d-1 ,其最佳值分别为 654～ 689℃和 1 2 0 0～ 2 4 65mmol·dm-2 ·d-1 。在温光两个因素中 ,当一个因素 (在棉铃发育所需下限以上 )相对不足时 ,另一个因素可以补偿 ,其补偿值约为 1 7.5mmol·dm-2 d-1 ℃ -1 。补偿后棉铃可以完成发育 。
Research on the temperature and the effective radiation captured by bolls on different nodes in growth period during 1997～1998 indicate: The development of bolls is completed under the joint acts of temperature and light .The range of effective accumulated temperature (≥15 ℃)needed for boll's growth is 534～710℃, while that of the effective radiation is 620～4000 mmol·dm -2 d -1 . The best number is 654～710℃ and 2465 mmol·dm -2 d -1 . As for the two factors, when one lover (the lover limitation needed for boll's growth) is relatively in sufficeincy, the other one may compensate, thus bolls can still fully developed, but with a lover weight and fiber quility.
