【Abstract】 Precision Agriculture is the main trend of global agriculture development. Variable Rate Fertilization is an important way of utilizing this kind of technique. The traditional fertilizer application in our country is based on experience of farmers. A lot of fertilizer can not be absorbed by plants due to extra fertilizer,and the extra fertilizer would pollute environments. This doesn’t meet the needs of agricultural modernization of our country. Therefore changing the traditional way of fertilizer application is imperative for sustainable development. The fertilization intelligent decision-making sustaining system according to the foreign advanced experience was put forward,which can meet the situlation of our country.Moreover ,the function,structure and implementation of the system were expounded .Finally,the key techniques in the research work of the system design were mainly discussed.更多还原
