摘要
对龙须草物候期进行了研究。结果显示,鄂西南山地龙须草完成生育期 15 6天,≥ 5℃有效积温15 6 5.0 8℃,最适相对湿度 85 %,需降水量 792mm,营养生长期 3～ 4月,生殖生长期 5～ 6月,种子成熟期 6～ 7月。
The phenological period of Eulapiopsis binata is studied and the results are as follows:the vegetation period is 156d;effective accumulated temperature( ≥5 ℃)is 1565. 08 ℃;the optimum relative humidity is 85%,the rainfall amount requirement is 792mm;the nutritional growth period is 3-4 months;the reproductive growth period is 5-6 month and the mature period of seeds is 6-7 months.$$$$
