Method］ The effective components from the stem segment of D. stramonium was extracted with distilled water, and with the treatment with distilled water as CK, the effects of extracted liquid from stem segment of D. stramonium on seed germination and seedling growth of tomato, pepper, amaranth and catnip were studied.

方法］用蒸馏水浸提曼陀罗茎段内的有效成分，以蒸馏水处理为对照，研究曼陀罗茎段浸提液对番茄、辣椒、苋菜、荆芥种子萌发和幼苗生长的影响。

Result］ The extracted liquid from D. stramonium could decrease the germination rates of 4 vegetables and the seed germination of tomato and pepper. After treatment by 0.2, 0.4 g/ml extracted liquid , the seed germination of tomato and pepper were decreased by 10.2％, 9.4％ and 46.7％, 34.7％ than that of CK resp. The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

结果］曼陀罗浸提液可降低4种蔬菜种子的发芽速率，降低番茄和辣椒种子的发芽率；0.2、0.4 g/ml曼陀罗浸提液处理后，番茄和辣椒种子的发芽率分别比对照降低了10.2％、9.4％和46.7％、34.7％。0.2 g/ml曼陀罗浸提液抑制蔬菜根的生长，而对茎的生长却表现出促进作用；0.4 g/ml曼陀罗浸提液对蔬菜根的生长有很强的抑制作用，对茎段生长的抑制作用因物种不同而有很大差异。

The findings indicate that, on the whole, the pattern of load transfer curves of adfreezing stress on a steel pipe pile stem and that of resistance stress on the pile tip are parabola and straight line, respectively; Due to the rheology effect, to different extent, adfreezing stress on the pile stem and resistance stress on the pile tip vary with time and relative displacement of pile-soil, respectively, and the settlement of pile tip varies with time tempestuously within 5 hours of loading, and then approximates to stability.
