The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.

The contents of nitrate nitrogen in the root and leaves reached the highest at the NH4(+) -N/NO3(-) -N ratio of 50:50. The activities of GS, GOGAT and the content of amylum increased with the ratio of NO3(-) -N decreasing and reached it's maximum at the NH4 + -N/NO3 - -N ratio of 100: 0. The content of ammonium nitrogen were the highest at the NH4 + -N /NO3 --N ratio of 75: 25, while the content of soluble sugar reached the highest at the NH4(+)-N/NO3(-) -N ratio of 25: 75. The content of flavones, chlorogenic acid and 3,5-O-dicoffeoylqunic acid were 57.2 mg x g(-1), 0.673% and 1.838% respectively, reaching the maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75; The content of luteoloside increased with the ratio of NO3(-) -N increasing and reached it's maximum at the NH4(+) -N/NO3(-) -N ratio of 0: 100. The yield of Ch. morifolium reached it's maximum at the NH4(+) -N /NO3(-) -N ratio of 25:75. Nitrogen form has some remarkable influence on the nitrogen metabolism, photosynthesis and growth, Nitrogen form conducive to the growth and quality of Ch. morifolium at the NH4(+) -N /NO3(-) -N ratio of 25: 75.
