- Abstract:
-
To ascertain the mechanism of different soil moisture conservation and soil structure improvement measures on water use of wheat and maize, a field experiment was conducted to determine the growth, photosynthetic physiological characteristics, yields, water use efficiency of water and maize and soil structure under the straw mulching, plastic film mulching, water retaining agent and organic fertilizer. The results showed that the ground cover and soil structure improvement measures effectively improved the soil aggregate structure and increased the content of soil organic carbon. What’s more, the different measures improved the photosynthetic characteristics of wheat and maize at different growth stages. The plant height, leaf area and biomass of wheat and maize at different growth stages increased, and the factors on production increased significantly, too. The plastic film mulching was more conducive to the improvement of wheat yield than the other measures, which increased the yield by 14.7% compared with the conventional tillage. For maize, the straw mulching and plastic film mulching treatments were conductive to the improvement of the yield, which increased the yields by 10.4% and 10.3%, respectively, compared with conventional tillage. For the total yields and water use efficiency of wheat and maize, the plastic film mulching treatment was the highest, increasing yields by 12.5% and 17.1%, respectively, compared with the conventional tillage. Correlation analysis showed that the annual total yields and water use efficiency of wheat and maize were closely related to soil moisture at different growth stages of wheat, leaf area in the filling stage, wheat yield, leaf area in big trumpet period of the maize, and soil organic carbon content.
