【摘要】 寒地城市因其寒冷的气温条件,对树种的选择较为苛刻,不加分析的选择树种,会导致树种选择的失败。寒地园林树种的选择需以寒地城市边缘树种以及其耐寒性为基础,综合利用寒地城市的气温数据对不同树种的影响进行选择。现以黑龙江省为例,根据黑龙江省主要城市的气温数据,从18种黑龙江边缘树种中选择出适宜应用于黑龙江园林的4种树种,对其进行试验论证。结果表明:山杏、金叶榆和四翅滨藜具有良好的寒地适应性,山樱桃的寒地适应性较弱。更多还原

【Abstract】 Because of its cold temperature conditions of city,the selection of tree species is relatively strict.It would lead to the failure of the tree species selection without analyzing the choice of tree species.The selection of the trees for garden is based on the marginal tree in cold city and theirs cold resistance.To choose trees through being trees plenty take advantage of influence,which the cold temperature data of the cities affected different trees.Taking Heilongjiang Province as an example,according to the temperature data of main cities in Heilongjiang Province,4kinds of trees were selected from 18 kinds of Heilongjiang marginal tree suitable for application in Heilongjiang garden,the experiments were conducted to demonstrate on the 4marginal tree species.The results showed that apricot(Prunus armniaca L.),gold leaf elm(Ulmus pumilacv.jinye)and Atriplex(Atriplex canescens)had a good cold adaptability,cold adaptability of mountain cherry(Prunus tomentos)was weak.更多还原
