outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 巴西中南部地区棉花播种期9-11月，采摘期2-5月；东北部地区棉花播种期为4-5月，采摘期为8-11月。一次性采摘，马克隆值高一些，马克隆值在3.6-4.2，可纺40-60S。</p><p style="max-inline-size: 100%; clear: both; min-height: 1em;

outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (1) 中西棉区或Cerrado棉区，包括中西部的3个州、东南部的1个州和东北部的1个州；(2) 南部棉区，包括南部的巴拉那和东南部的圣保罗2个州；(3) 东北棉区，包括东北部8个州。</p><p style="max-inline-size: 100%;

outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 巴西棉花基本品质：棉花品质类似于我国山东、河北棉花。巴西采用机器采摘，无三丝，纤维长度在28.5mm以上的棉花占45%，强力在27.1GPT以上的占61%，马克隆值为3.8-4.2的占72%，整齐度为80%，成熟度好，可纺性好，可纺40支以上纱。</p><p style="max-inline-size: 100%;

outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 质量管理方面，巴西采用美国农业部的国际标准进行检验，逐包取样，大容量高精度检验仪器（HVI）检验，采用条形码制度。</p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em;

对于我国用棉企业来说，使用巴西棉的唯一缺点就是运期较长，一般为2-3个月。</p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%;

墨西哥棉田依靠灌溉，灌区平均每公顷产棉975公斤（亩产65公斤），而自然降雨和半灌溉区棉产要低些，棉花除部分机械采摘，大部分人工采摘，墨西哥棉花全部为锯齿机轧棉。墨西哥棉区遍及南北各地，主要棉区在加利福尼亚湾的墨西卡利。沿西海岸的星那罗亚和索诺拉，三地产棉占全国产棉量的60%，中部的勒琴那和德力西亚产棉占22%。</p><p style="max-inline-size: 100%; clear: both;

outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 墨西哥棉花收获期在西海岸地区六月下旬开始，中南部和南部地区甚至到次年的2月3月份方能结束，持续8个月之久。</p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em;

墨西哥棉花：色泽洁白，长度一般，细度略粗，含杂较少，成熟度好；但轧花如同美国棉花，棉结较多，整齐度较差。</p><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%;
