Abstract: Study on characteristics of the matter accumulation and translocation of spring maize under different cultivation patterns to show the different yield, density and fertilizer of reasonable regulation and choose the best cultivation mode, which provided a theoretical basis for defer decrepitude. The ‘Jinshan27’ and ‘Xianyu335’ were grown under the farmer (NH), high yield (GC) and higher yield (ZGC) condition to study on characteristics of the matter accumulation and transportation of spring maize in west Liaohe Plain. The results showed that, dry matter accumulation per plant in each stage was NH > GC > ZGC, and the differences among three patterns with the advance of growth and development were significantly increased; population dry matter accumulation was ZGC > GC > NH, and the differences among different patterns reached significant level in the mature stage. Dry matter accumulation maximum rate per plant was NH > GC > ZGC, the maximum population dry matter accumulation rate in contrast. Dry matter translocation, translocation rates and its contribution rates to grain of vegetative organs were NH > GC > ZGC. The translocation rates of leaves were higher than stem-sheath and spike, and the spike was the smallest. For the vegetative organs contribution rates to grain, ‘Xianyu335’ performance for stem-sheath > leaves, ‘Jinshan27’ performance for leaves > stem-sheath; the contribution to grain of spike of ‘Xianyu335’ was higher than ‘Jinshan27’.
