辽南地区越橘根系分布特征
Characteristics of Root System of Blueberry in South of Liaoning Province
摘要
Abstract
Root distribution characteristics of five blueberry cultivers in brown soil area were examined. The results showed that(l)root range of 5 blueberry cultivars was 50 to 70 cm,centralized in 0-50 cm,(2)the root biomasses of high-bush blueberry and half high-bush blueberry were high, the root biomass of low-bush blueberry was low,the root biomass of the roots with diameters of 1~3 mm was the highest,diameter <C1 mm ranked the second, diameter>3 mm was the lowest;(3)the root length densities of the cultivars of Coville, Northcountry and Brunswick were high, and low for the cultivars of Northland and Blomidon was lesse; the density of the roots with diameter <1 mm was the highest,diameter between 1~3 mm ranked second, and diameter>3 mm was the lowest; (4)the root biomass and root density of 5 blueberry cultivars distributed in 30-40 cm soil layer,mostly in 0~20 cm soil layer, among them, the roots of Coville and Northcountry centralized in 0~10 cm soil layer, in 10~20 cm soil layer for Blomidon,and in 0-20 cm soil layer for Northland and Brunswick with uniform distribution.关键词
