气候因子对青稞千粒重影响的研究

Effects of climatic factors on thousand kernel weight of highland barley

摘要: 运用统计学原理与计算方法，在系统分析研究西藏自治区山南地区多年气候因子对青稞主要发育期千粒重影响规律的基础上，建立了千粒重-气候模型。试验结果表明，开花～乳熟期平均气温约18．2℃ 、平均日照时数长是增加千粒重的有利条件；乳熟～成熟期高温少雨或低温阴雨天气均降低千粒重。

Abstract: Using the principles of statistics and analysis method，effects of climatic factors on thousand kernel weight in main development stage of highland barley in Tibet are analysed．The thousand kernel weight-climate model of highland barley is performed．The results from tests show that，from the floweriag to milking stages，ahout 18．2℃ for mean temperature and more radiation are favor of improving thousand kernel weight．but high temperature and partly raining or cold and rainy weather cause thousand kernel weight to be decreased.
