| Abstract: | Based on the geographic information platform ARCGIS,2 817 soil samples were collected by means of GPS network,and 12 high-yield paddy demonstration bases were established in the 107 000 hm~2 paddy farmland of Shanghai suburbs.The examination results indicated that using the method of rapidly testing soil nutrients and the recommended rate of fertilizer application averagely increased paddy yield by(31.5 kg/666.7 m~2,)or 6.04%. |
