Field observation about the influence of ridge tillage on the growth of rape in rainfed cropland;

Combining conservation tillage and ridge tillage is a useful method to solve the problems of low-temperature, spring drought and wind erosion.

Ridge tillage is a kind of soil and water conservation tillage used frequently in the rainfed farmland of sandy areas.

Efeects of different ridge culture and mulch pattern on soil physico-chemical properties,water consumption feature and maize yield;

To research further function of maize by planting of ridge culture and straw mulch, the paper summarizes the influence of physical and chemical characteristics, the temperature and moisture of soil and the farm microclimate.

Aiming at the water resources waste of conventional flood irrigation,ridge culture combining with film mulching for spring wheat was applied in this paper.

Effect of bed-planting on grain yield and quality of wheat;

Mechanism of yield formation and decrease of winter wheat yield in bed-planting in rain-fed areas;

The effects of bed-planting system on the soil environment in the rhizosphere, photosynthetic characteristics of flag leaf, grain yield and quality of three kinds of gluten wheat were studied in Henan province during the period 2003～2005.

Analysis of use efficiencies of irrigation water, nitrogen fertilizer and solar energy for bed planting system in wheat;

Through the experiment of winter wheat on furrow planting and bed planting,the results showed that soil water of different irrigation treatments had fallen on 0~120 cm soil layer,the significant fall on 0~90 cm layer and the slight fall on 100~120 cm layer.

Preliminary study on raised-bed planting for common wheat after rice in Sichuan basin;

The paper summarizes the suitable types of crop raised-bed planting for different areas and the improvement of the soil system.

Influences of combing ridge and no-tillage on pore characteristics of soil aggregates in a rice-based cropping system;
