摘要
研究了在丰产性方面具代表性的三年生或四年生无核葡萄(克瑞森、皇家秋天和红宝石无核)的根系分布特点。结果表明,丰产性差的克瑞森无核具有垂直性生长的主根,丰产性好的红宝石无核和皇家秋天没有垂直性生长的主根,但不结果的皇家秋天植株具有垂直性生长的主根;上层土壤细根(直径小于0.3大于0.1cm)数量与下层土壤粗根(直径大于0.3cm)数量的比值反映了葡萄幼树的丰产性能。
Distribution characteristics of root system of Crimson (4 years old), Autumn Royal (3 years old) and Ruby seedless (4 years old), which were representative for fertility, were studied. Crimson has poor fertile capability, the other two show fine fertility. The results showed that Crimson had vertical-growth main roots, while Autumn Royal and Ruby seedless had no vertical- growth main roots. But no-fruit-bearing Autumn Royal has the vertical-growth main roots. The ratio of the amounts of thin roots (0.3 cm >ID>0.1 cm) in upper soils to thick roots (ID>0.3 cm) in lower soils reflected the fertility capability of young grape trees.
