The results showed that soil organic carbon, water-soluble organic carbon and humin decreased gradually. Extracted humic substances presented an increasing trend at first and then decreased. Relative proportion of humic acid in HE decreased at first and then increased during the initial stage of corn stalk decomposition, which indicated that the formed rate of fulvic acid was faster than HA. Then PQ dropped gradually and reached stabilization, which indicated that FA and HA transformed into each other for some time and then reached balance.

Result In 5 kinds of chemical treatments, treating Z. macrostachya seeds with 20 % NaOH solution for 20 min and then cleaning the seeds with clear water got the best effect of breaking seed dormancy. By this treatment, the seed germination potential reached 83.5% in 10 d, being 58.2 % higher than CK; reached 85 % in 15 d, being 55 % higher than CK, which was near to the potential germination rate of Z. macrostachya seeds. Compared with CK, the germination duration was obviously shortened.

When initial NO3--N was leached, the correlation coefficients between soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation with raygrass nitrogen uptake were decreased to 0.613 and 0.607, respectively, and both reached 5% significantly level. However, the correlation coefficients between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogen uptake were raised obviously, and all reached 5% and 1% significant level.
