- Abstract:
- A field experiment was carried out in the Loess Tableland to study the effects of fertilization and soil water storage before sowing on the grain yield of winter wheat. The results showed that the soil water contents of the 3 types of soil water storage before sowing were relatively high, and the soil relative water contents of the 2 m soil layers were 72%, 82% and 94%, respectively; the precipitation during wheat growth period was 301 mm in the experimental year, exceeding the average annual precipitation of 39%. The results also showed that the yield varied with the soil moisture contents significantly, the yield and harvest index decreased due to high water content when no fertilizer was used, and the nutrient input could significantly increase the yield of winter wheat and the yield was of little difference under different soil water contents; fertilization significantly increased the spike number, kernel number per spike, 1000-grain weight and plant height of winter wheat, and could improve water utilization efficiency and precipitation utilization efficiency; fertilization increased water consumption of winter wheat, but the yield was improved significantly; under the condition of precipitation in the test year, the high soil moisture content could cause the deep leakage of soil moisture, the depth of water permeation was over 5 meters.
