飞燕草在大兴安岭地区的引种驯化

Introduction and domestication of Delphinium grandiflorum L.in Daxinganling

对飞燕草的引种驯化试验进行了详细记录。飞燕草在大兴安岭地区生根发芽早,新芽具有很强的耐寒特性。飞燕草植株花序较大,植株较高,抗风能力不强。在连雨季节,飞燕草种植地会积水,苗木沤根腐烂,部分全株死亡。在人为干预情况下,一年内花期可以达到3次,即使不用人为干预,第二年变成了留床苗,不存在缓苗期,第三批花蕾也是可以正常开放的。随着生长年限的增长,植株抽生的枝条也不断增多,花量更多,更具观赏价值。从试验结果看,飞燕草引种成功,掌握了飞燕草的生长习性和苗木培育引种移栽驯化技术,为以后的花卉引种驯化奠定了理论基础。

The experiment of introduction and domestication of Delphinium grandiflorum L.is recorded in detail:Delphinium grandiflorum L.takes root early in Daxinganling area,and its new shoots have strong cold resistance.The plants of Delphinium grandiflorum L.have larger inflorescences,higher plants and weak wind resistance.In the continuous rain season,the water will accumulate in the planting area of Delphinium grandiflorum L.,the retting roots of seedlings will rot,and part of the whole plant will die.In the case of human intervention,the flowering period can reach three times in a year.Even if there is no human intervention,the second year becomes bed seedling,there is no slow seedling stage,and the third batch of flower buds can open normally.With the increase of growth years,the number of branches of the plant is also increasing,the amount of flowers is more,more ornamental value.From the results of the experiment,the introduction of Delphinium grandiflorum L.was successful.The growth habit of Delphinium grandiflorum L.and the technology of transplanting and domestication of seedlings were mastered,which laid a theoretical foundation for the later introduction and domestication of flowers.
