在西班牙中部,于1984～85年对行距间,行距对产量以及产量组成的影响进行了田间试验当播种量从10粒/m~2增加到50粒时,籽粒产量由4.59吨/公顷增加到5.23吨/公顷。当密度增加时,每株豆荚数减少,当行间距离由50厘米增加到80厘米时,产量显示出平均由5.77吨/公顷到4.23吨/公顷的下降趋势。但行距对产量的组成的影响不是太大。
In central Spain, a field experiment was conducted in 1984-85 on the effects of row spacing and row spacing on yield and yield components. When the seeding rate was increased from 10 grains / m 2 to 50 grains, the grain yield was increased from 4.59 tons / ha to 5.23 tons / hectare. As the density increased, the number of pods per plant decreased, and as the distance between rows increased from 50 to 80 cm, the yield showed an average downward trend of 5.77 tons / ha to 4.23 tons / ha. However, the effect of row spacing on the composition of the output is not too great.
