水分、光照与硼交互作用对大豆产量因子的影响

Effects of boron,soil moisture and light on the agricultural characters and yield of soybean

文章采用盆栽试验研究不同水分、光照和硼对大豆产量因子的影响。研究表明,单株荚数、单株粒数、单株粒重均随土壤水分含量增大而增大;随光照减弱而减小。正常光照条件,施硼缓解水分对单株荚数的胁迫,增加单株荚数;施硼缓解干旱对单株粒数的胁迫。遮光条件,施硼不能缓解干旱、淹水对产量因子的胁迫。

The experiment was conducted to study effects of different soil moistures, light and boron on the agricultural characters and yield of soybean by pot culture. The results showed that soil moisture and light influenced pods, seed numbers, and yield significantly. At the normal light intensity, boron increased pods per plant under moisture stress, and seed numbers per plant under drough stress. Under shehering condition, boron benefited Yield forming factors.
