摘要: 以农科一号、农科二号莲雾为试材,观察莲雾根系在土壤中的分布与形态特征。农科一号、农科二号莲雾根系垂直根深均达80cm;农科一号根系主要集中在20~60cm的土层内;农科二号莲雾根系集中在0~40cm的土层内,直径在5mm以下的根占总根数的绝大部分。以6年生农科二号莲雾为例,水平根幅为4.56m×2.88m,活性细根分布在距离根颈1.34~2.28m之间。研究结果可为施肥等栽培措施提供依据。

Abstract: The varieties of Wax Jambu,Syzygium samarangense var.nongke 1 and var.nongke 2,were studied for observing in their root system morphology and distribution.The vertical depth of root system reached to 80 cm in the soil layer for both varieties.The root system of 'var.nongke 1' was mainly fastened in the 20-60 cm of the soil layer,while that of 'var.nongke 2' in the 0-40 cm.The diameter in single root measured was between 0-5 mm mostly the root system.The horizontal root area of the 6-year-old 'var.nongke 2' was in 4.56 m × 2.88 m.The distribution of active root tops was reached in 1.34-2.28 m away from the root collar.
