| Abstract: | Applying orthogonal method,the study of high-yield cultivation techniques of poplar plantation was carried out for 8 a. The results showed that the volume of 4m×2m area was the highest and the current annual increment of 4m×4m per hectare was the highest .Arid area contained with carbonated chernozem was the superior area to fertilize phosphatic fertilizers. The suitable depth of soil preparation were 50～60cm and the optimum combination was: Phosphatic fertilizers were fertilized 150g per cave and the density were 4m×2m and the depth of soil preparation were 50～60cm. |
| Keywords: | arid area high-yield forest of poplar density volume |
