通过对花椒短枝型新品种——秦安一号与当地品种剌椒根系垂直分布规律的对比分析,结果表明:两品种侧根均较发达,在0~60cm土壤剖面中,94%以上的侧根为根径小于2mm的毛根;2个品种均为浅根性树种,90%以上的侧根分布于0~100cm的土层中;在耕作层(0~30cm),秦安一号的根数累计为27.43%,刺椒为45.28%;秦安一号70%以上的根系分布在耕作层下,抗旱性较刺椒强。
The results showed that the lateral roots of both cultivars were well developed, and the lateral roots of more than 94% of 0-60 cm soil profiles were Roots of roots less than 2 mm in diameter were rooted. As for the two cultivars, they were shallow-rooted trees with more than 90% of the lateral roots distributed in 0-100 cm soil layer. In the tillage layer (0-30 cm), the root number of Qin’an-1 was 27.43% , Jiantao 45.28%; Qin’an one more than 70% of the roots distributed in the tillage layer, more resistant to Prickly ash.
