气象条件与苎麻农艺性状形成关系研究

多点试验结果表明：高温、强光和高蒸发量增加株高，却减少有效株数，不利高产优质；生长中后期总日照时数较多则利于茎粗、皮厚、鲜皮出麻率和产量提高并降低原麻含胶率；雨日和雨量较多能增加有效株，提高支数；较高相对湿度使茎粗、皮厚、有效株、鲜皮出麻率及产量和支数提高、原麻含胶率下降。总辐射量大抑制除株高之外其它经济性状发育，造成低产劣质。

Analysis on the Influences of Weather Parameters to theDevelopment of Ramie Agronomic Characteristics

The result from multiple-sites experiment showed:More total sunshine hours in the mid-late growth stage was helpful to enhance stem diameter,bast thickness,bast stripping percentage and raw fiber yield,and to lessen the gum content of raw fiber,During the whole growth period,high temperature and evaporation,strong sun light decreased effective stalks,raw fiber yield and fiber quality despite of some stimulation to plant height of ramie;More precipitation amount and rain days helped to increase effective stalks and fiber fineness;Higher relative humidity of air was propitious to aggrandize stem diameter,bast thickness,effective stalks,bast stripping percentage,raw fiber yield,to meliorate fiber quality and to reduce gum content in raw fiber,High total solar radiation was only good to plant height but disadvantageous to other economic characters,resulting in low raw fiber yield and fiber quality.
