土壤盐碱性对3个树莓品种生长特征的影响

Influence of Saline-alkali Soils on the Growth of Three Raspberry Varieties

为了比较不同地区的土壤对树莓各品种生长特征的影响,以天津市西青区轻度盐碱地和蓟县微酸性土壤为试验地,以3个树莓品种(诺娃、香妃和红宝)为试材,测定了树莓植株的单株叶片数、单叶面积、主枝长等指标。结果显示:西青盐碱地的总叶片数比蓟县微酸性土壤的多,分别为诺娃1.22倍、红宝1.45倍、香妃1.41倍;西青盐碱地的诺娃、红宝、香妃的单叶面积是蓟县微酸性土壤的1.86倍、1.39倍和0.87倍;西青盐碱地诺娃、红宝、香妃的主枝长是蓟县微酸性土壤的3.94倍、0.61倍和0.80倍。因此,研究认为试验的3个树莓品种更适宜在轻度盐碱性土壤上生长。

In order to compare the differences of growth characteristics among three varieties planted in saline-alkali soils,the varieties of Nuowa, Xiangfei and Hongbao planted in slightly acidic soil of Jixian and in mild saline-alkali soil of Tianjin Xiqing district were taking as material, and the number of leaves per plant, leaf area, main branch length were measured. The results showed that the number of leaves per plant was more in plants of Xiqing than Jixian, respectively, 1.22 times in Nuowa, 1.41 times in Xiangfei and1.45 times Hongbao. Leaf area of Nuowa, Hongbao and Xiangfei in Xiqin increased respectively up to 1.86,1.39,0.87 times compared with plants in Jixian. The main stem length was more up to 3.94,0.61,0.80 times respectively. Therefore, the three varieties of raspberry were suitable to grow in mild saline-alkali soil.
