火棘引种栽培适应性试验

Introduction,Cultivation and Adaptability of Pyracantha fortuneana

在研究火棘(Pyracantha fortuneana(Maxim.)Li)生物学特性及对比原产地和试验地生境的基础上,选取了影响植物生长的光照、土壤、水分3个主要环境因子,划分了各因素水平,采用L9(34)正交试验方法,安排9个处理栽培区,从甘肃康县引种180株火棘进行了栽培适应性试验。经试验观测,火棘在试验地3月上旬叶芽萌动,3月中旬展叶,花期4月中旬—6月上旬,果期6月中旬—7月下旬,生长期较原产地约缩短10 d;自然光照条件下,火棘枝条生长量较原产地增加4.4%,其叶长、花径的生长差异不明显。试验表明:火棘在试验区能正常生长发育,开花结实,适宜在试验区及相应地区城镇绿化、公园建设及荒山造林工程中推广栽植。

An experiment was conducted to study the adaptability of Pyracanthafortuneana in terms of its biological characteristics and the environmental factors of the original producing area （Kang County, Gansu Province） and the introduction area （ Lanzhou City, Gansu）. Three main factors, including light intensity, soil and moisture, were classified into various factor levels, and nine cultivation areas were arranged by the orthogonal test method. The vegetative buds of P. fortuneana germinate in early March, unfold in mid-March, blossom during mid-April and early June, and bear fruit during mid-June and late July. P. fortuneana seedlings in the original producing area had 10-day longer growth duration than those in the introduction area. The branch increment of the introduction area increased by 4.4% compared with that of the original producing area. The experiment indicates that P. fortuneana can grow, blossom and bear fruit normally in the introduction area. P. fortuneana is suitable to be popularized in urban afforestation, park construction and barren hill afforestation.
