摘　　要：江苏省中国科学院植物研究所引种16个黑莓品种到河南封丘,经过3年露地栽培试验,结果发现,黑莓在该地种植较为困难,主要表现在种植成活率低,16个品种的平均成活率只有44.97%;冬季冻害严重,几乎所有品种都有不同程度冻害,早春冷害也较明显。在较好肥水条件下,16个品种枝蔓年生长量平均为5.50 dm^3,不到适栽区(南京)的一半;叶片黄化现象严重;即使冻害较轻的品种,平均株产量也只有1~2kg。因此,封丘地区不适宜推广种植黑莓,其制约因素主要是土壤碱性和冬季严寒。Sixteen cultivars of blackberry have been introduced to Fengqiu of Henan Province by Institute of Botany, Jiangsu Province and the Chinese Academy of Sciences. After three -year culture test in open field, it was found that blackberry planting was difficult in this area mainly because of low survival rate of plants, serious frost damage and chill injury. The average survival rate of the sixteen cuhivars was only 44. 97% , and different cultivars had different degrees of frost damage in winter and chill injury in early spring. Under the better conditions of water and fertilizer, the average annual increment of branches and tendrils of the 16 cuhivars was 5.50 din3 ,which was less than half of that in suitable area Nanjing. The yellowing phenome- non of leaves was serious and the average production was only 1 -2 kg per plant. Therefore, Fengqiu was not suitable for planting blackberry because of the main restriction factors of alkaline soil and winter cold.
