【摘要】 研究表明,生态因子对棉纤维诸指标的影响程度,气象因子大于土壤因子。根据棉纤维品质的2.5％跨距长度、比强度、麦克隆值3项主要指标经数理统计分析,可初步划分5个棉纤维品质生态区,其分布特征是:由鄂西、鄂南向鄂东、鄂北走向,其纤维长度变短,麦克隆值增大,比强度增加。更多还原

【Abstract】 The relationship of fiber quality and different ecological conditions have been systematically studied. The result is as follows: factors of meteorology is more important than those of soil in all ecological conditions. The planting region in Hubei province can primarily be divided into five ecological areas according to the fiber qualities. Based on the statistical data for 2.5％ length, strength and microndire from 95 nots in 3 years, the distributive characteristics in different areas about fiber quality are as follows the fiber length became shorter, the microndire and the strength increased from E xi(West of Hubei), E Nan (South of Hubei) to E Dong (East of Hubei), E Bei (North of Hubei).更多还原
