【摘要】 对人工栽培条件下蒙古扁桃的植株性状和传粉结实情况进行了研究,结果表明:栽培蒙古扁桃有明显的大小年现象。从蒙古扁桃植株上的花朵分布看,花集中分布于植株中上部。从枝条的花朵分布看,中部花枝的花朵均匀着生,上部和下部枝条的花朵着生在花枝的顶端。栽培条件下蒙古扁桃首次结实的结实率达39%,但种群自然更新困难。人工栽培条件下蒙古扁桃植株生长状况优于野生环境条件下,从低矮灌丛变为乔林式,栽培管理简便,花期提前,结实率提高,增加了西北寒旱区的行道树树种选择空间。人丁栽培对于蒙古扁桃的种群恢复有重要意义。更多还原

【Abstract】 The plant characters,pollination and fruiting of AmygdalusmongolicaundeT cultivation condition were studied.The results showed that the cultivation of Amygdalusmongolica has obvious fluctuations fruiting phenomenon among different years.From the distribution of flowers on the plant,the flowers are concentrated in the upper part of the plant.From the view of the branches,the distribution of flowers on central branches were uniform distribution,the upper and lower branches of the flowers are borne on the top of branches.Under the cultivation condition,the fruit-settingrate of Amygdalusmongolica was 39%for the first time,but it was difficult for the population to renew naturally.Amygdalusmongolica is better than that of the wild plants grown under cultivation conditions,the growth mode translate from shrub to tree forest,thecultivation methods is simple,theflowering time go ahead,the fruit-setting rate improved,increasedthe selection space in the northwest regions.Artificial cultivation is important for the population restoration of Amygdalusmongolica.更多还原
