| 摘 要： | 利用2000～2008年4月21日～10月20日≥10℃积温资料,对河北省棉花熟区进行了重新划分。结果表明:中熟区向北大幅度扩展,中早熟区北移而面积缩小,早熟区向北扩展。通过河北省由南向北三个地区种植不同熟性品种试验发现,在覆膜条件下,同属中熟棉区的冀南应试种中晚熟品种,而冀中应种植中熟品种,作为早熟区的冀东应种植早熟品种。

| Abstract: | Based on the local data of ≥ 10℃ accumulated temperature from April 21st to October 20th from 2000 to 2008, the cotton areas in Hebei Province were regionalized anew according to variety maturity. The results showed that mid - maturity region expanded north greatly; mid - early - maturity region moved north and the area decreased; early - maturity region also expanded north. Different maturity varieties were planted with plastic film mulching in three sites from south to north in Hebei Province, and the results indica- ted that the mid -late maturity varieties should be planted experimently in south Hebei, while mid maturity varieties should be planted in central Hebei, though they belonged to mid maturity regions. Early maturity va- rieties should be planted in east Hebei. |
