Abstract: The objective of this study is to provide a technique for high2yielding spring maize cultivation by analyzingeffects of different nitrogen managements on dry matter accumulation,partition and transportation. There are three nitrogenmanagements:Zero nitrogen fertilization(ZNF),Recommended nitrogen fertilization(RNF),Traditional nitrogen fertiliza2tion(TNF). The results showed that neither RNF nor TNF could obviously improve dry matter accumulation,LAI,ear2leave photosynthetic rate and grain yield in the first year. However,in the second year,ZNF achieved yield reduction of1210 % and 1116 % comparing with RNF and TNF respectively. Furthermore,RNF could not only reduce nitrogen input,but also improve dry matter transportation from other organs to grain,the proportion of which reached 2211 %,and was611 % higher than TNF.

Key words: Spring maize, Dry matter partition, Dry matter transportation
