| Abstract: |
| Jujube Mills of 2a was used in a barrel planting experiment to study the effects of different water deficit treatments on soil moisture and growth of the trees at the flowering to fruit-setting stage. Two deficit treatments were set in the experiment. The result indicated that after irrigation, the moisture of T1(CK) and T2 dropped obviously, in addition, the process can be divided into two stages, and the descend rate of T3’s moisture was slow; Deficit irrigation restrained the growth of the trees’ diameter significantly; Deficit irrigation also restrained the growth of branches, and the growth of branches in three treatments pr
esented linear relation. In the period of deficit irrigation, the spad value between the CK and the other treatments had no significant difference. |
