不同蓝莓品种在浙江遂昌引种试验

为了筛选出适合在遂昌县种植的蓝莓品种,以夏普蓝、奥尼尔、灿烂、顶峰4个蓝莓品种为试材,对种植5年后的树高、冠幅和产量等指标进行完全随机区组设计对比试验的结果表明:灿烂和夏普蓝品种明显优于其他2个品种,其树体高大茂盛,树高149.00 cm、142.14 cm、冠幅162.00 cm、159.11 cm,200 m²产量为518.70 kg、505.40 kg;平均单果直径和质量奥尼尔最大,为1.52 cm和1.59 g,但单位面积产量最低,为228.90 kg;适宜在800 m～1 050 m海拔高度生长,海拔320 m时需做好夏季7—8月的遮阴降温工作。为此,灿烂和夏普蓝品种可以作为主栽的优良品种在遂昌县800 m～1 050 m海拔段中进行种植推广。

Introduction Experiment of Different Blueberry Varieties in Suichang County,Zhejiang Province

In order to screen out blueberry varieties suitable for planting in Suichang county,four blueberry varieties,namely Sharpblue,O'Neal,Britewell and Climax were selected as test materials by using a complete randomized block design.After five years of planting,the tree height,crown width and yield were compared.The results showed that(1)the Britewell and Sharpblue varieties were obviously superior to the other two varieties,with taller and more luxuriant values.For the Britewell and Sharpblue varieties,the tree height was 149.00 cm and 142.14 cm respectively,the crown width was 162.00 cm and 159.11 cm respectively,and the yield in 200 m2 was 518.70 kg and 505.40 kg respectively.(2)The O'Neal variety had the largest average single fruit diameter and mass(1.52 cm and 1.59 g),but had the lowest yield per unit area(228.90 kg).(3)The suitable planting altitude was 800−1050 m,and it was necessary to do shading and cooling when they were planted at the altitude of 320 m in summer from July to August.In summary,the Britewell and Sharpblue varieties can be planted and promoted as the main cultivars at the altitude of 800−1050 m in Suichang county.
