摘  要：
以平邑甜茶[Malus hupehensis(Pamp.)Rehd.]幼苗为材料,研究了栽培容器形状对幼苗新梢生长、幼苗根构型特征及根系营养吸收特性的影响。结果显示,生长在"深窄盆"中的幼苗新梢生长量最大,主根粗,侧根多且短,毛细根丰富,对钙及锌的吸收能力较强,但根系活力及根系对磷、铁的吸收能力较弱;"等高径盆"中幼苗新梢生长量小,根冠比接近1,主根细短、一级侧根少且粗长,对钾的吸收能力较强;"浅宽盆"幼苗根冠比最大,一级侧根数量、长度和粗度居中,二级侧根粗长,根系活力及根系对磷、铁的吸收能力较强,但对钾、钙及锌的吸收能力弱。

摘  要：
A systematic study was made about the effect of cultural container shapes on root architecture, nutrients uptake by roots and growth of shoots of Malus hupehensis(Pamp.) Rehd. seedling planted in the different shapes of pottery-pots. The results revealed that when the seedling of M. hupehensis (Pamp.) Rehd. growing in the pots of deep and narrow, the growth of shoots was the biggest, and primary root was thick, lateral roots was short, the numbers of lateral roots and the fine roots were more. And the root activity and the uptake ability of P and Fe of the roots were low, but the uptake ability of Ca and Zn of the roots was high. When growing in the equal height and diameter pots, the growth of shoots was the smallest, the root-top ratio was close to 1. And primary root was thin and short, first lateral roots were thick and long, and less numbers of the first lateral roots. And the K-uptake ability of the roots was higher. When growing in the shallow and wide pots, the root-top ratio was the biggest, and the numbers, thickness and length of first lateral roots were between that in deep-narrow pots and in equal highness and diameter pots, second lateral roots were thick and long. And the root activity and the uptake ability of P and Fe of the roots produced in shallow-wide pots were higher, but the uptake ability of K, Ca and Zn of the roots was lower.
