北京地区夏大豆农艺性状与气象条件关系初探

The initial study of the relationship between meteorological factors and agronomic characters of soybean in Beijing area

  • 摘要: 试验研究气象条件对夏大豆各生育阶段农艺性状的影响结果表明,增加生育期间积温可获得良好的夏大豆植株性状和产量性状,出苗~开花期气象条件对夏大豆植株性状影响显著,有效分枝始节、结荚高度除与该期气象条件有关外,还与播种~出苗期气象条件有关;而单株英数和单株产量与该期降水量及降水日数呈显著正相关,与生育前期和后期气象条件无关。夏大豆株高、茎粗、主茎节数与生育前期和后期气象条件均无关。开花~成熟期气象条件主要影响夏大豆百粒重。

     

    Abstract: The efect of meteorological factors on agronomic characters in diferent develop periods of summer soybean is studied in this paper.The results show that by increasing the accumulated temperature in devdoping period of summer soybean,the better plant and yield characters can be obtained.The meteorological factors of seeding-flowing period have a marked effect on the plant character of summer soybean.The efficient ramification commence node and growing legumen height have relationships with the meteorological factors in this period and sowing-seeding period .The number of growing legumen and yield per plant have a marked positive correlation with the precipitation and precipitation days in this period ,and have no correlation with the meteorological factors in prophase and anaphase of develop period .The plant height,stem diameter,and node amount of caulis have no correlation with the meteorological factors in prophase and anaphase of develop period also .The meteorological factors in flowing- maturing period mainly affect the 100-grain weight of summer soybean.
