- 摘要:
- 为明确沼液对大豆生育状况及产量的影响，在田间试验条件下研究喷施不同浓度沼液对大豆生长发育及产量的影响。结果表明：喷施沼液增加叶绿素SPAD含量，提高大豆根瘤数与根瘤重，更大程度地增加大豆的生物产量及百粒重，进而提高大豆产量。其中20%处理为最佳效果，叶绿素SPAD含量增加2.1，地上部鲜重增加0.4 g?株-1，干重增加0.29 g?株-1，地下部鲜重增加1.7 g?株-1，干重增加0.41 g?株-1。根瘤数增加3.6个?株-1，株高增加0.67 cm?株-1，根长增加0.07 cm?株-1。百粒重增加0.88 g，大豆产量达1 806.0 kg?hm-2，增产率为7.79%。
- Abstract:
- In order to determine the effect of biogas slurry on growth status and yield of soybean,the effects of spraying different concentrations of biogas slurry on the growth and yield of soybean were studied under field experiment conditions.The results showed that,spraying biogas slurry increased the content of chlorophyll SPAD,the number of soybean nodules,the nodule weight,the biomass production and 100-seed weight of soybeans to further increase soybean yield.The 20% treatment was the best,the SPAD content of chlorophyll was increased by 2.1,the fresh weight of the shoot increased by 0.4 g per plant,the dry weight was increased by 0.29 g- per plant,and the fresh weight in the underground increased by 1.7 g per plant.The number of root nodules increased by 3.6 strains per plant,the plant height increased by 0.67 cm strain per plant,and the root length increased by 0.07 cm per plant.100-seed weight increased by 0.88 g,soybean yield reached 1 806.0 kg?hm-2--,and yield increased by 7.79%.
