天津蓟州区4个蓝莓品种生长特性比较

Growth Characteristic of 4 Blueberry Varieties of Jizhou District in Tianjin

为筛选适宜在微酸土壤中生长的蓝莓品种,以蓟州区马伸桥苗圃的4个蓝莓品种(‘蓝丰’、‘蓝金’、‘伯克利’、‘布里吉塔’)为试材,通过测量其干粗、株高、新梢生长量、新梢数、冠幅等指标,研究了其生长特性。结果显示:‘布里吉塔’蓝莓干粗最粗为8.20 cm,‘蓝金’的干粗最细只有3.80 cm;‘布里吉塔’蓝莓植株最高,为1.83 m,其余依次是‘伯克利’1.65 m、‘蓝金’1.37 m,‘蓝丰’1.19 m;新梢最长的是‘布里吉塔’为25.11 cm,其次是‘蓝金’13.78 cm,‘蓝丰’13.67 cm,‘伯克利’12.89 cm;新梢数最多的是’布里吉塔’9.89枝和‘蓝丰’9.33枝,其次是‘蓝金’7.11枝和‘伯克利’6.56枝。‘布里吉塔’的冠幅最大为1.43 m,‘伯克利’次之,为1.30 m,再次是‘蓝丰’1.10 m和‘蓝金’1.07 m。隶属函数综合分析显示:4个蓝莓品种的生长由强到弱依次为:‘布里吉塔’、‘伯克利’、‘蓝丰’、‘蓝金’。

In order to screen the suitable varieties of blueberry for cultivation in slightly acid soils, growth characteristics were determined according to the stem diameter, plant height, shoot biomass, shoot numbers, and canopy of 4 varieties of blueberry （ ＇Bluecrop＇, ＇Bluegold＇, ＇Berkeley＇, ＇Brigitta＇ ） from Mashenqiao nursery of Jizhou. The results showed that the stem diameter of ＇Brigitta＇was the longest （8.20 cm）, ＇Bluegold＇was the thinnest （3.80 cm）, the plant of＇Brigitta＇was the highes （ 1.83 m）, followed by＇Berkeley＇ （ 1.65 m）, and then was＇Bluegold＇ （ 1.37 m）, ＇Bluecrop＇was the lowest （ 1.19 m） . The shoot diameter of＇Brigitta＇was the biggest（25.11 cm）, followed by＇Bluegold＇and＇Bluecrop＇, which were 13.78 cm and 13.67 cm;＇Berkeley＇ was the lowest, 12.89 cm. The shoot numbers of＇Brigitta＇was the highest （9.89）, followed by＇Blneerop＇and＇Bluegold＇, which were 9.33 and 7.11.＇Berkeley＇was the lowest （6.56） . The canopy of＇Brigitta＇was the widest （1.43 m） followed by ＇Berkeley＇ and＇Bluecrop＇, which were 1.13 m and 1.37 m, ＇Bluegold＇was the lowest, 1.07 m. The growth characteristic of the blueberries from strong to weak was＇Brigitta＇, ＇Berkeley＇, ＇Bluecrop＇and＇Bluegold＇in turn, according to the subordinate function.
