玉米田杂草马唐的生长特性研究
The Growth Characteristics of Digitaria Sanguinalis A Weed in Maize Fields
【摘要】 在田间和室内条件下研究了马唐的生长特性。结果表明 ,马唐种子具有短期休眠 ,其出苗的适宜土壤深度为 0 .5~ 4 .0cm ;随着密度的增加和出苗时间的推迟 ,马唐的单株生长量逐渐下降。
【Abstract】 The growth characteristics of Digitaria sanguinalis(D.s) was investi-gated under both fields and a greenhouse conditions. The results showed that the seed had a relative short dormancy. The suitable covering soilsickneen for seed emerging was 0.5~4.0cm. As the density being increased and the daley of emerging time the growth of a single plant of D.s was reduced.
