山杏新植幼树地上、地下生长量调查研究

Growth of Newly-Planted Prunus sibirica Saplings on the Ground & Underground

于2006年和2007年,对山杏新植幼树进行了地上、地下部生长量调查研究,结果表明,山杏新植幼树的地径、树高、根径等指标第2年的生长量均成倍于在圃地至栽植成活后第1年的生长量;第2年地下平均每株根系总生长量与地上平均幼树高生长量相比少318mm;第2年与第1年根径、根长生长量存在显著相关关系。

The growth on the ground & underground of the newly-planted sapling of Prunus sibirica in the year of 2006 &2007were investigated.Result shows that:the growth of the ground diameter,the tree height,the root diameter of newly-planted Prunus sibirica saplings in the second year increased remarkably than that of one-year-old saplings which were survived in the nursery;the total root growth per plant underground are 318mm less than that of the height growth of saplings on the ground in the second year;the root diameter &the length growth are significantly correlated between the first &the second year.
