| Abstract: | The experiment in the model of fertilizer application in rape was carried out in Jinsha county and the superiorly planning model of fertilizer application was obtained.The result was as follows: 10.7 kg N,7.5 kg P,6.0 kg K,and the proportion of N∶P∶K was 1∶0.7∶0.6 so that the average rape output may reach above 2 250 kg/hm~2. |
