In this thesis, seed germination and root elongation test, early growth test were performanced by chemical spiked (Cu, Zn, Pb and Cd; Phenanthrenen, Pyrene; and1, 2, 4-trichlorobenzene) in four types of soils (red load soil, meadow brown soil, chestnut soil and dark brown soil) using wheat, Chinese cabbages , tomatoes , turnip and scallion as plants: The toxicity of heavy metals Cu.

本文选择4类典型土壤（红壤、草甸棕壤、暗棕壤和栗钙土），以（小麦、白菜、萝卜、西红柿、大葱）为供试植物，进行了重金属（Cu、Zn、Pb、Cd）、有机氯、多环芳烃污染的植物种子发芽与根伸长抑制试验；植物早期生长试验研究；以草甸棕壤为供试土壤，进行了重金属（Cu、Zn、Pb、Cd）单一、复合污染条件下的蚯蚓急性毒性实验；以草甸棕壤、污染土壤和生物修复土壤进行蚕豆根尖实验和土壤原生动物实验。

In vitro micropropagation of Taraxacum formosanum Kitamura was established to get maximum shoots multiplication rate by cultivating stem-node on MS medium supplemented with BA 0.6 mg/L+ NAA 0.06 mg/L and rooting rate achieved 100% by cultivating on MS and 1/2 MS medium or it supplemented with IBA 0.2 mg/L for 3 weeks.

试验结果发现龙珠顶芽优势强，在腋芽的增殖上，於BA 0.1 mg/L + NAA 0.01 mg/L之MS培养基，虽然可获得最多芽数，但产生的腋芽数只有2.3，且高度较矮，不易切芽，建议以MS为增殖培养基；在发根方面，不管在MS、1/2 MS或是添加IBA，培养4周后，发根率均为100%。

The 1/2 MS medium supplemented with 1.0 mg·L-1 BA and 0.1 mg·L-1 NAA was very beneficial to the protocorm differentiation and propagation of D.candidum .The highest protocorm propagation index was obtained from the medium containing the activated carbon.The highest root numbers and length were observed in plants growing in 1/2 MS medium containing 0.5 mg·L-1 NAA.

结果与结论：添加20%马铃薯液有利于种胚的萌发，种胚萌发率为79.37%；BA 1.0 mg.L-1和NAA 0.1 mg.L-1最有利于原球茎增殖，培养基中添加2%活性碳原球茎增殖倍数高；NAA有助于试管苗的生根，不同含量NAA以0.5 mg.L-1时试管苗平均根数最多和平均根长最长。

Adjusting the packing 1 Pump packing (1) continue to hand tighten the squeeze cap nut;(2) after opening the pump, adjust the gland nut, this time to allow a little more leakage;(3) slowly tighten the squeeze cap nut, gradually reduce the leak until the leak to an acceptable level;(4) If the disclosure of a sudden stop, should be back to tighten the gland nut, packing re-adjustment in order to prevent overheating;(5) adjust the leakage rate can reach a steady state.

泵用盘根（1）继续用手拧紧压盖螺母；（2）开泵后，调整压盖螺母，此时截止阀允许有稍多的泄漏；（3）缓慢地拧紧压盖螺母，逐渐减少泄漏，直到泄漏达到可接受的程度；（4）如果泄露突然停止，应回拧压盖螺母，重新调节以防止盘根过热；（5）调节泄漏率达到一个稳定状态即可。

Method］ 5 matrices: M1(50% peat + 50% perlite),M2(40% peat + 60% perlite),M3(50% peat + 50% chestnut soil),M4(40% peat + 60% chestnut soil) and M5(100% peat) used for Euonymus fortunei cutting in container were tested and the effect of the different matrices on the rate of callus induction and root growth,the length and number of root,and the growth amount of Euonymus fortunei was investigated.［Results］ The results showed that the best effect on Euonymus fortunei cutting was from the M1,in which,the rate of root growth,callus induction,the length of root and the number of new branch were 87%,88%,68.0 mm and 4.6 branches,respectively.

方法］ 采用5种基质配比，分别为M1（50%泥炭+50%珍珠岩）、M2（40%泥炭+60%珍珠岩）、M3（50%泥炭+50%栗钙土）、M4（40%泥炭+60%栗钙土）、M5（100%泥炭）对扶芳藤进行容器扦插育苗试验，对不同基质引起的扶芳藤愈伤率、生根率、根长、单株根系数目、新生枝数及新生枝生长量进行调查分析，［结果］结果表明，基质M1中扦插的扶芳藤生根率、愈伤率最高，分别为87%和88%；根长最长，为68.0 mm；平均新生枝数最多，为4.6条，效果最佳。
