- 摘要:
- 于2010和2011年对甘肃省3个大豆种植区各示范县进行了抽样调查,收集甘肃大豆不同种植区的主栽品种及产量相关数据。在此基础上分区统计,并采用多元逐步回归判断不同种植区影响大豆产量的关键因素。结果表明,各种植区大豆主要为春播,同时沿黄灌区与陇东旱塬区的部分区域存在夏播。河西灌区的种植密度显著高于沿黄灌区和陇东旱塬区。大豆单产为河西灌区最高,沿黄灌区居中,陇东旱塬区最低。在农艺和产量性状中,株高的高低排序依次为河西灌区、沿黄灌区、陇东旱塬区。陇东旱塬区的单株荚数最高,其次为河西灌区,沿黄灌区最低。单株粒数的高低排序与单株荚数的排序相反。陇东旱塬区的百粒重最高,其次是沿黄灌区,河西灌区显著低于前2个种植区。品质性状中,平均蛋白质含量高低依次为沿黄灌区、陇东旱塬区、河西灌区。脂肪含量为河西灌区最高,陇东旱塬区次之,沿黄灌区最低。蛋脂总量高低排序依次为沿黄灌区、陇东旱塬区、河西灌区。根据各种植区对产量建立的逐步回归方程的标准化回归系数来看,株高是影响河西灌区和沿黄灌区大豆产量的主要因素,影响陇东旱塬区大豆产量的首要因素为单株粒数,然后依次为种植密度、单株荚数、百粒重和株高。
- Abstract:
- The survey of technology demonstration counties in 3 soybean planting regions of Gansu was conducted in 2010 and 2011 respectively.Yield-related traits data of dominating varieties planted in Hexi irrigation area(HXIA),Yellow-River Irrigation area(YRIA)and Dry plateau of East Gansu(DPEG)was collected.After the survey,the key yield limiting factors in different regions were determined with stepwise multiple regression analysis.Results showed that soybean was mainly planted in spring in Gansu province,but in some part of YRIA and DPEG,soybean was planted in summer.Planting density of soybean in HXIA was significantly higher than that in YRIA and DPEG.Soybean yield was the highest in HXIA,middle in YRIA,and lowest in DPEG.Among the agronomic traits,HXIA,YRIA and DPEG were listed in descending order for plant height.Pod number per plant was highest in DPEG,the second in HXIA and lower in YRIA,while seed number per plant had opposite trend in different planting regions.The 100-seed weight was highest in DPEG,middle in YRIA,and significant lowest in HXIA.Protein content and total content of protein and fat all were the highest in YRIA,lowest in HXIA,while fat corrtent had opposite trend.According to the standard regression coefficient of yield,plant height was the main factors that effected soybean yield in HXIA and YRIA.In DPEG,primary determinant factor of soybean yield was seed number per plant,followed by planting density,pod number per plant,100-seed weight and plant height.
