| Abstract: | The effect of different irrigation levels on the growth of Pinus tabulaeform is, Platycladus orientalis and Robinia pseudoacacia were studied in drought. The results showed that the growth of trees in diameter and height was fastest at the irrigation level of 1. 0 times the rainfall than others,volume growth of Pinus tabulaeformis and Platycladus orientalis was 2. 9 times and 1. 6 times of the controlled experiment respectively,and it can make a profit of 575 Yuan/hm2 and 2566 Yuan/hm2 in a year. |
