| 摘 要： | 以科棉1号为试验品种，在江苏不同生态区设立试验点，研究温、光因子对纤维品质的影响。结果表明，4个地点温光因子存在显著的地域差异。逐步回归分析表明，影响4桃纤维品质的温光因子不同。影响纤维长度的主要是气温日较差，影响伏前桃和早秋桃比强度主要是最高温度，影响伏桃比强度的主要是日照时数和气温日较差，晚秋桃比强度则主要受最高温度和气温日较差的调控。影响伏前桃麦克隆值的主要是最低温度和日均温，对伏桃和早秋桃纤维麦克隆值有明显影响的是日照时数，影响晚秋桃麦克隆值的主要是气温日较差。 |

| Abstract: | To investigate the effects of temperature and light on fiber quality in Kemian 1, experiments were carried at four different ecological sites in Jiangsu Province. The results indicated that temperature and light at four sites varied significantly. Further regressive analyses indicated that there were different dominant factors affecting different fiber indexes in four types of bolls. The dominant factor affecting fiber length is daily temperature difference. Fiber strength of pre-summer bolls and early autumn bolls was dominantly affected by maximum temperature, while the fiber strength of summer bolls was mainly influenced by daily sunshine duration and daily temperature difference. As for the fiber strength of late autumn bolls, it was mainly influenced by maximum temperature and daily temperature difference. The micronaire readings of fiber in pre-summer bolls were mainly affected by minimum temperature and daily average temperature. The micronaire readings of fiber in summer bolls and early autumn bolls were primarily affected by daily sunshine duration. The micronaire readings of fiber in late autumn bolls were mainly affected by daily temperature difference. |
