摘要

The research was conducted to determine levels of intercrop competition to a varying extent depending on the relative density of each crop under the field conditions that are commonly used in normal production. Soybean was interplanted in green wheat during the jointing (1987, 1989) to fully headed (1988) stage of wheat. Results showed that soybean does not significantly compete with wheat in this cropping system. Crop growth rate in narrow rows soybean, as leaf area increased, eventually approached that of monocrop soybean at 6 to 7 g m -2 d -1 in 1987 and 1989, but not in 1988 when crop growth rate was similar for narrow rows, skip rows and wide rows. Temperature and precipitation data suggest that a residual stress effect on crop growth rate occurred in 1988 despite the use of irrigation. Crop growth rate for skip rows and wide rows soybean never equaled monocrop soybean nor displayed a trend toward `catching up` with monocrop soybean during the sample period indicating that other residual effects may be occurring in addition to the obvious row width differences.
