Water consumption characteristics and soil environment for summer corn under no-tillage with mulch;

Analyzing reason that low water use rate in karst area,combining with the characteristic of no-tillage with mulch,it is suggested that no-tillage with mulch is an effective approach improving water use in karst area.

Effects of no-tillage with straw mulch on water saving and soil temperature;

Effects of no-tillage with straw mulch on evapotranspiration and soil water for pea under storage irrigation;

(2) The project will reduce vegetation coverage rate 0.

After analyzed,the exciting laser intensity,the coverage rate and the numerical aperture of objectives are selected for experimental research.

In addition, the sandstorm decreasing is directly resulted by the coverage rate increasing in recent years.

The characteristics of hydrogen permeation were explained in terms of the hydrogen coverage and the porosity of deposits during the electrodeposition of Zn-Ni alloy.

The distributing characterastics of the polymetallic nodule s coverage in China Pioneer Area;

The inconsistency of the density degression grid ring is listed as incresing the fabric density and the retain of the original fabric coverage.

Methods Bias of estimates and coverage of 95% confidence intervals were compared across the three statistical methods through computer simulations according to a pupil based somatic study under different values of the regression coefficient parameters and intraclass correlation coefficient.
