| 摘 要： | 利用1990—2010年陇西县白条党参产量统计资料和生育期气象资料,分析了白条党参产量与生育期主要气象因子间的相关性.结果表明,陇西县白条党参产量与年降水量、9月份降水量及平均土壤绝对湿度间均存在线性正相关,泊松相关系数分别为0.7329、0.6229、0.5041;与7月份平均气温、7—8月份≥0℃活动积温均存在线性负相关,泊松相关系数分别为-0.5928、-0.6305

| Abstract: | The relevance between the yield and the main growth period meteorological data of white Dangshen were analyzed,using the statistical data of yield and growth period meteorological data of Longxi white dangshen from 1990 to 2010.The results indicated that the yield of Longxi white Dangshen is positive linear correlation to the amount of annual railfall,railfall in September and the absolute humidity of average soil,respectively.The Poisson correlation coefficient is 0.732 9、 0.622 9、 0.504 1,respectively,and exits negative linear correlation to ≥0 ℃ accumulated temperature from July to August,the Poisson correlation coefficient is-0.592 8、-0.630 5,respectively. |
