abstract={Maize (<i>Zea mays</i> L.) is one of the valuable food crops in China as well serves as a model organism for biological research worldwide. The experiment was conducted in the maize experimental base of Shanxi agricultural in Shanxi Province, China. Organic fertilizer was the main plot, 0 and 1.5 t/ha (Chicken mature<b> </b>Organic fertilizer). Five treatments were set up ¢Ù Control CK (0g sludge + 0g chicken manure) ¢Ú Organic fertilizer "H0" level (sludge + chicken manure 0g) ¢Û "H1" level of organic fertilizer (sludge + organic fertilizer 60 g/kg) ¢Ü "H2" level of organic fertilizer (sludge + organic fertilizer 120 g/kg) ¢Ý Organic fertilizer "H3" level (sludge + organic fertilizer 180 g/kg), 4 replicates. The results indicated that the effects of municipal sludge, and different amounts of chicken manure at the<b> </b>first seedling stage compared to CK treatment (without municipal sludge, and chicken manure), Plant height, root length, above/blow ground dry weight, of all treatments increased first, and then decreased, and reached the maximum values in H1 treatment, respectively, and contents of total Cu and total Zn in calcareous brown soil of maize at the first seedling stage were 24.8-40.2 mg/Kg and 54.7-149.4 mg/Kg applied quantitative municipal sludge, and the highest amount of chicken manure increased respectively. At the second seedling stage<b> </b>compared to CK, the Zn content was significantly increased, respectively. The contents of total Cu and total Zn in calcareous brown soil of maize at the second seedling stage ranged from 27.0 to 42.9mg/kg, and from 55.1 to 164.5mg/kg, respectively. In third seedling stage compared to CK, the Cu content in H3 treatment was not significantly increased, and the other treatments were significantly increased. The contents of total Cu, and total Zn in calcine brown soil of maize at the third seedling stage ranged from 24.4 to 36.3mg/kg, and from 52.3 to 172.6mg/Kg, respectively. The grain starch content at maturity stage was the highest at H2<SUP> </SUP>and the lowest at CK. The effects of CK on soluble sugar, sucrose and starch contents of mature grains were not significant. There was a H2, and H3 significant interaction between the content of sucrose, and starch in the mature stage. The grain protein content and grain protein yield of H2<SUP> </SUP>combined to H3 were the highest, and significantly higher than those of other treatments. The overall trend of Cu transport coefficient increased and while Zn transport coefficient decreased with the increase of chicken manure application, respectively. The grain protein content and grain protein yield of H2<SUP> </SUP>combined to H3 were the highest, and significantly higher than those of other treatments. Effects on soil heavy metal content where compared to CK and H0 treatments, the total Cu, total Zn, available Cu, and available Zn in calcareous brown soil of maize at the first, second and third cropping stages increased significantly with the increase of chicken manure application rate, but it was far lower than the national secondary soil standard.},
