摘要
[目的]研究籽粒苋的根系生长特征,为栽培管理提供依据。[方法]研究自繁绿苋ZL01、大田红苋黑籽ZH01、红苋K472、大田绿苋黑籽ZH02 4个籽粒苋品种的根系生长特性。[结果]籽粒苋根系长呈"先快、后慢、更快、再慢"的变化趋势,其变化特征与自身的营养条件和土壤紧实度有关,根冠比随着生育期的延长呈下降趋势。[结论]籽粒苋根系的生长最快时期应加强管理,以促进根系生长。
[Objective] The root system growth characteristics of grain amaranth were studied to provide the basis for management.[Method] The root system growth characteristics of four species including ZL01,ZH01,K472 and ZH02 were observed and studied.[Result] The results showed that the root growth speed appeared rule of fast,slow,more faster and slower,which had a relationship between growth rule and root＇s nutrient and the soil compactness.Ratio between root and shoot declined with growth period extend.[Conclusion] Management must be strengthened to promote root growth when root of grain amaranth grow fastest.
