摘要
以引种到贵州的"乌皮"、"红灯"、"大紫"、"芝罘红"、"龙冠"、"先锋"樱桃为试材,采用壕沟法研究了供试材料根系分布情况。结果表明:小于2mm的吸收根占33.54%,大于2mm、小于10mm的细长骨干根占59.92%,大于10mm骨干根占6.54%;根密集分布在距干与距土表40cm的区域内,此范围之外,离中心干与土表越远根系越少。
With ＇ Pitch-black＇, ＇ Hongdeng＇, ＇ Dazi ＇, ＇ Zhifuhong＇, ＇ Longguan＇ cherry as the materials, the distribution of their tree roots were observed with Oskamp method. The results showed that cherry tree distributed in the area of 300 cm distance from the main trunk and the depth of 90 cm. The distribute rate of the roots（the diameter≤2 mm） was about 33. 54%,the 2 mm≤the diameter≤10 mm was about 59. 92% and the diameter≥10 cm was about 6. 54%,the 40 cm lateral distance from main trunk was the dense regions of the cherry tree roots,outside of this range,the amounts of the tree root reduced with the increase of the depth and the lateral distance from the main trunk.
