国外优良材用竹种阿帕斯竹引种栽培试验

阿帕斯竹出笋期5月中旬～10月中旬,7月上旬～8月中旬为出笋盛期;单株埋秆育苗的出笋数、成竹数分别是单株埋蔸育苗的3.9倍、3.8倍,而新竹径级较埋蔸的下降43.5%,两种育苗方法可结合应用;竹丛结构调控可显著提高竹丛出笋数(21.9%)和新竹地径(84.1%),退笋率降低36.9%;综合出笋成竹数、新竹地径的季节性施肥效果,以6月最佳,其次为3月。

Experiment for Introduction and Cultivation of Choiceness Bamboo Gigantochloa apus from India

The shooting period of Gigantochloa apus is from mid-May to mid-October,and abundant stage during early July to mid-August.Shoot emerge number and its amount of burying culm individually is 3.9 and 3.8 times covering rhizome,however,diameter of new bamboo decreases by 43.5%.So we can integrate the two seeding techniques.Adjustment of bamboo clump structure promoted shooting number(21.9%)and diameter of new bamboo(84.1%)evidently,and shoots degradation ratio decreased by 36.9%.Making a comprehensive view to the number of shoot bamboo emerge,diameter of new bamboo,and the effect of fertilizing seasonally,the best period of propagation is during June,followed by March.
