青海野生马蔺驯化栽培试验

Cultivation and Utilization of Iris lactea pall. var. chinenehsis Koidz in Qinghai Province

为掌握青海野生马蔺的生态习性、生长发育规律及物候现象,探讨其生产繁育技术和栽培管理措施。采用不同种子处理方法和不同海拔种植,观测其发芽特性、生物学特征、物候指数及生长量和分蘖分株情况。雪藏催芽处理种子,是高海拔地区进行马蔺种子处理较为理想的方式;温度、土壤状况等因子是影响马蔺萌芽及分蘖的主要因子;不同海拔栽培地马蔺的物候期及其各阶段的时间具有明显差异,为229～269d。马蔺对生长环境的适应性很强,节水抗旱,栽培容易,管理粗放,是干旱地区城市园林绿化中颇有推广应用前景的地被植物。

Iris lactea pall.var.chinenehsis Koidz is a wild ground cover plant widespread in china,Which are cultivated in different localities in Qinghai province.Domestication and observation revealed that it blossoms in May with 3～4 weeks and fresh white flowers.As its seeds are very stiff and difficult to sprout,so it must be disposed before seed.It mainly germinated by storage in snow,dip in warm water and chemical reagent.The first method was the most effective.The life history of Iris lactea pall.var.chinenehsis Koidz in different localities were 229～269 days.Different regions had different environmental conditions,including the climate,soil,vegetation etc.The life history of Iris lactea pall.var.chinenehsis Koidz varied greatly,and the life history of the plant decreased with elevation.The plant was drowning tolerant,drought and tread tolerant and could be used as a promising material in garden landscape.
