树莓在合肥地区的引种研究

Introduction Experiment of Raspberry in Hefei Area

[目的]为合肥地区树莓的推广奠定基础。[方法]以11个树莓品种为试材,观测研究了各个品种在物候期、适应性、丰产性以及抗性等方面的综合表现。[结果]各品种的萌芽期都在3月下旬,撒尼黑、延K1、顺K2能适应合肥地区的土壤和气候条件,且较耐干旱,保存率为100%。黄莓、欧洲红、双季红及托乐米表现较差,托乐米的保存率仅为10%,黄莓、欧洲红、双季红根蘖率较高,但植株长势较弱且不耐干旱。延K1、撒尼黑单株产量可达1.1 kg以上,且单果重可达10.5 g;其次为顺K2,单株产量可达0.9 kg,黄莓、欧洲红、双季红单株产量最少。大部分品种抗病虫害性较强,少数品种如欧洲红、双季红的抗旱性较弱。[结论]延K1、撒尼黑、顺K2适合在合肥地区大面积推广。

[Objective ] The aim was to lay the basis for the generalization of raspberry in Hefei area. [ Method ] With 11 varieties of raspberry as tested materials, the comprehensive performance of each variety on the aspects such as phonological phase, adaptability, productivity, resistance were observed and studied. [ Result] The germination stage of all varieties was in the last ten day of March. Sanihei, Yan K1, and Shun K2 could adapt to the soil and climate conditions in Hefei area. They were relatively resistant to drought and their preserving rate was 100%. The performance of Huangmei, Ozhouhong, Shuangjihong and Tuolemi was bad and the preserving rate of Tuolemi was only 10%. The root tillering rates of Huangmei, Ozhouhong, Shuangjihong were higher, but their growth vigor was weaker and was not resistant to drought. The yield per plant of Yan K1, Sanihei could reach more than 1.1 kg and its weight per fruit could reach 10.5 g; the following was Sun K2 and its yield could reach 0.9 kg/plant. The yield per plant of Huangmei, Ozhouhong and Shuangjihong were least. Most of varieties were strongly resistant to disease and pest, while few varieties such as Ozhouhong, Shuangjihong had a weak resistance to drought. [ Conclusion ] Yan K1, Sanihei and Shun K2 were suitable to be generalized in Hefei area in large scale.
