| Abstract: | Based on the geographic information platform ARCGIS, 2002 soil samples were collected by means of GPS network, and 22 high-yield paddy demonstration bases were established in the 4 000 hm^2 paddy farmland of Shanghai suburbs Dimensions farm. The examination results indicated that using the method of rapidly testing soil nutrients and the recommended rate of fertilizer application av- eragely by 10 402.95 kg·hm^-2, 9 429.0 kg·hm^-2 increased paddy yield by 973.95 kg·hm^-2, or 10.33%, or 1 558.2 yuan ·hm^-2. This provides grounds for the population of precision fertilizing technique of rice farmland. |
