摘要
本文旨在从根系形态生理角度对葡萄根系形态的数字化研究作出努力,以揭示试验中根系的数字形态与葡萄树体关系。在武汉南郊以17个常用葡萄品种作根系测试材料,试验结果表明,有较多品种试树的根干比树主干粗,两者生长关系呈正相关。以巨峰为主的5年生树根域宽约79cm,深约58cm,总根数约有40条根。以欧亚种为主的4年树根域宽约56cm,深约38cm,约有28条根。
This paper aimed to make efforts for numerical research of the grape root system morphology from the aspect of root system morphological physiology. The relationship between the numerical morphology of the root system and the grape trees in the test was revealed with 17 general grape varieties planted in the southern suburban of Wuhan as samples. The results showed: The root trunks’ diameter (A) was usually thicker than the tree trunks’ diameter (B) in the majority of the grape varieties and the correlation between A and B was positive. The width and the depth of the root system zone of cv‘Kyoho’ grape series of 5-year- growing trees were about 79cm and 58cm respectively, and the total root number is about 40. Correspondingly, the width and the depth of the root system zone of Vitis vinifera L. of 4-year-growing trees are about 56cm and 38cm respectively, and the total root number is 28.
