多功能植物闭鞘姜无公害人工栽培技术研究

Pollution-free Cultural Practices for Multi-purpose Plant Costus speciosus

通过对闭鞘姜栽培技术的研究,掌握种苗繁育技术,并在扦插方法上获得创新性突破,"分枝顶芽扦插"成苗率达95.6%～98.9%。筛选出最佳栽培模式——网棚种植,每公顷可产鲜根茎60.6t。

Top buds of branches of Costus speciosus were used for cutting for mass propagation of planting materials, and the cuttings had a survival rate of 95.6%-98.9%. Cultural patterns were also tried and selected, and the results found that planting under net shade was an optimum cultural pattern. Cuttings grown under the net shade yielded as high as 60 600 kg/ha of fresh tuber.
