油莎豆块茎萌发特性的初步研究
Sprouting Characteristics of Yellow Nutsedge ( Cyperus esculentus L.) Tubers
摘要
Abstract
The effects of germination under different soaking temperature, environmental temperature, culture substrate and three sizes on tubers of Yellow Nutsedge (Cyperus esculentus L.)were studied. The germination and growth of Yellow Nutsedge tubers from different districts were analyzed. The results showed that presoaked tubers in warm water (35 ℃)was beneficial to the germination of Yellow Nutsedge, and when the temperature of water was below 20 ℃, it was unsuitable to germinate. Sandy loam with good permeability was suitable for planting. Yellow Nutsedge, but clayey loam was unsuitable. When selecting tubers and seeding, big and plump tubers was very important. In addition, the adaptability of Yellow Nutsedge species selected from different districts had not correlation with geographic latitude. According to the results and the environmental condition of Hainan Province, it would be necessary to breed and cultive in Hainan Province as soon as possible.关键词
