Effects of Spring Wheat/Maize, Spring Wheat/Sunflower Intercropping on Soil Moisture
soil moisture in 0-120 cm soil depth of spring wheat/maize and spring wheat/sunflower intercropping during annual crop growth periods and crops yields were determined in Hetao irrigation district
Inner Mongolia Autonomous Region. The results showed that the seasonal changes of soil moisture evapotranspiration intensity of spring wheat/maize
spring wheat/sunflower intercropping were bimodal curve
while spring wheat
maize and sunflower sole cropping were unimodal curve
and the soil moisture evapotranspiration amounts of intercropping patterns were higher than sole cropping patterns. The crop yields and land equivalent ratio of intercropping patterns were higher than sole cropping patterns
but intercropping patterns reduced soil water use efficiency and water equivalence ratio
reduced irrigation use efficiency and irrigation water equivalence ratio in crop growth periods and annual crop growth periods. In order to improve soil water use efficiency
the intercropping area should be reduced
or intercropping crops should be segregated with a bank
and crops should be irrigated respectively according to the different water requirement.
