为进一步明确白三叶草对杂草的化感作用，研究了不同浓度的白三叶草地上部分水浸液、根系分泌物、挥发物对苘麻和稗草种子发芽率和杂草幼苗生长过程中生理生化机理的影响。

The same depth applies for a potted rose, with the first inch or so of the branches below soil level, and the hole wide enough for the root ball, there is no need to tease the roots out but better to leave the root ball intact.

对于盆栽的月季苗，种植深度要求根茎基部埋在土壤水平线下大约相距1英寸。坑的宽度应能容纳整个根球。没必要去修整根系最好保持根系的完整。
