| Abstract: |
| The experiment was conducted to study the effects of fertilization on water utilization,agronomic characters and economic benefit of dryland wheat planted on sides of film in furrow lines.The results showed that the application of fertilizers could significantly increase WUE by 1.1～3.1 kg/(mm·hm2),and advance the development of wheat.Under the treatments of low fertilizer,mid fertilizer and high fertilizer,the yield of wheat was increased by 731.5 kg/hm2,1 461.0 kg/hm2 and 1 648.5 kg/hm2,respectively,compared with the unfertilized treatment;and the yield increase rate was 25.5%,50.9% and 57.4%,respectively.The economic benefit was found to be the highest under the mid fertilizer treatment with N 118.1 kg/hm2,P2O5 94.5(kg/hm2) and K2O 60.0 kg/hm2. |
