| Abstract: | The formula application by measuring soil method was tested in rice field with lower yield to gain the aim of rational application and raise economic benefit in Weng'an county,Guizhou.The results showed that the mathematics model between application amount and yield y= 298.538 12.074N 6.083P 13.061K-0.53N2-0.759P2-0.703K2 0.438NP 0.106NK 0.154PK,the optimum application amount of N,P2O5 and K2O was 12.11 kg/667m2,6.65 kg/667m2 and 8.99 kg/667m2 respectively and the optimum yield was 490.65 kg/667m2. |
