Analysis of relationships among different parameters of irrigation uniformity in fully-compensated micro-irrigation system;

Experimental research on drip irrigation uniformity at low-pressure

Furthermore,a mathematical equation of irrigation intensity and uniformity of the menbrane hole irrigation has also been abtained and the conflict of irrigation uniformity and extending length is solved.

This paper deduces respectively the formula calculating the flux deviation rate based on the influence of different warp, and put forwards the method to calculate irrigation uniformity.

The application of the BP model shows that the simulated efficiency of the application Ea and the distribution uniformity DU from two models have similar variatio.

Field experiments were conducted to investigate the influences of border dimensions and irrigation variables on the performance of water advance under straw mulch,irrigation efficiency and distribution uniformity(DU).

For a typical field, the resulting performance parameters, such as application efficiency and distribution uniformity were appreciably reduced with increase in the standard deviation of field surface elevations (S d), which was used to evaluate the land.
