Abstract:

In this study, the effects of different organic fertilizers on corn yield quality and soil environment were studied with no fertilizer (T1), chemical fertilizers (T2) and different organic fertilizers replacing partial chemical fertilizers (T3 and T4) by field experiments. The agronomic traits of maize plants under fertilizer treatments were better than those under T1. Compared with T2, the growth of maize plants was promoted under organic fertilizer treatment (T3 and T4). The stem diameter and leaf length of maize plants under T3 treatment were significantly increased compared with T2 (P<0.05, the same below) by 11.94% and 4.53%, respectively. Compared with the control, the maize yield could be significantly increased with 14.27%-17.17% under fertilizer treatments, but it was insignificant (P>0.05, the same below) between T2-T4. Compared with T2, the ear length of T3 was significantly increased 7.12%, the protein and fat content under T4 were significantly increased with 7.21% compare with T3, and the soluble sugar content under T3 was significantly increased with 61.54% and 77.97% compare with that of T1 and T4, and the organic matter content in soil were increased by 64.52% and 27.38% under T3 and T4, respectively. In the correlation analysis of all indexes, the content of protein and fat in kernel was significantly positively correlated with the content of total nitrogen (r = 0.868, P <0.01), which indicated that the accumulation of protein, fat and other nutrients in kernels could be promoted by improving the absorption of nitrogen. In conclusion, the growth of corn plants, ear quality and content of soil organic matter were be improved under organic fertilizers replacing partial chemical fertilizers, which could be used as the recommended fertilization strategy for improving the quality and yield of spring maize under regional fertilizer application reduction.
