| Abstract: | From sowing to mature, corn experienced a number of fertility and reproductive period. The demand for nutrients of corn, which is totally different in each growth period, shows a downtrend after rising at the maximum in the period which corn grow exuberantly.According to corn characteristics of fertilizer requirement at different growth stages, it is important to apply fertilizer pertinently with the aim to guarantee a high and stable yield of corn. The current research status of Chinese topdressing machinery of corn was generalized and summarized in this paper, besides the whole type Chinese corn fertilizer machines had been elaborated respectively from two aspects of roof fertilizer and top dressing. Therefore the development prospects of mechanical fertilizer were discussed. |
