摘要
通过对引种的长柄扁桃(Amygdalus pedunculata Pall.)生长发育、耐寒性、耐旱性及病虫害等调查分析,结果表明,在黑龙江省西部进行长柄扁桃播种,其耐寒性强,耐旱性较强;害虫种类主要有顶芽卷叶蛾、天幕毛虫、李小食心虫等,主要以为害叶部和果实为主。其中,顶芽卷叶蛾和天幕毛虫发生频度较大,但对树体生长发育未造成明显影响。
Growth and development,cold tolerance,drought tolerance,and occurrence of diseases and insect pests of introduced Amygdalus pedunculata were analyzed.Result shows that Amygdalus pedunculata which planted in the western region of Heilongjiang Province has strong cold tolerance and stronger drought tolerance;the main pests are Spilonota lechriaspis,Malacosoma neustria testacea&Grapholitha funebrana,and they mainly damage the leaves and fruits.Among them,Spilonota lechriaspis and Malacosoma neustria testacea occur more frequently,but they have no obvious impact on the growth and development of the tree.
