- Abstract:
-
In order to explore effects of different fertilization and cultivation ways on soil profile moisture content and corn yield in red soil under seasonal drought conditions, the field experiment was launched in 2012 which includes treatments of straw coverage, pig manure, tillage. Soil profile moisture content, soil temperature in continuous drought and grain yield of spring and autumn corns were analyzed. The results showed that under the same cultivation and pig manure condition, soil profile moisture content was affected significantly by straw cover or no cover. Compared with no straw cover, the soil water contents in 0—5 cm, 5—10 cm, 10—20 cm of straw coverage increased by 27.93%, 5.91% and 1.41%, respectively, in the period of spring corn growth, and the increment rates were 15.74%, 7.71%, 2.59% in autumn corn. Meanwhile, the straw coverage could significantly increase surface soil temperature at corn flowering stage, the soil temperatures in 0—10 cm and 10—20 cm of straw coverage reduced by 13.92% and 2.26%, respectively, in spring corn, and they decreased by 0.30% and 2.69% respectively in autumn corn. In all treatments, the biomass and grian yield were the highest when straw coverage, pig manure and tillage were combined in spring and autumn corn.
