Effects of Stomatal Regulator on Seedling Quality of Rice

摘要: 通过对机插水稻秧苗喷施不同浓度的硝普钠溶液和黄腐酸钾溶液,探究气孔调节剂对水稻秧苗素质的影响。结果表明,喷施不同浓度的硝普钠溶液和黄腐酸钾溶液均可引起秧苗气孔导度减小,促进秧苗地下部干物质增加和提高根系活力。黄腐酸钾溶液还可增加秧苗株高、茎基宽、地上部干物质量,提高叶绿素含量。以在苗期喷施10 mL/L的黄腐酸钾溶液较为适宜。

Abstract: In this paper, the effects of stomatal regulators on seedling quality of rice were studied by spraying sodium nitroprusside solution and fulvic acid potassium solution on machine-transplanted rice seedlings in plate. The results showed that spraying different concentrations of sodium nitroprusside and fulvic acid potassium solution could cause the decrease of stomatal conductance, promote the increase of below-ground dry weight and effectively improve root activity. Under the treatment of fulvic acid potassium solution,plant height, base width, below-ground dry weight and chlorophyll content were increased. It was suggested that it is more suitable to spray 10 mL/L fulvic acid potassium solution for machine-transplanted rice seedlings in plate.

Key words: stomatal regulator, sodium nitroprusside solution, fulvic acid potassium solution, rice, seedling quality
