本文通过对小麦套种玉米不同带型的试验研究表明，套种作物总产与玉米产量呈高度正相关（ｒ＝０．９４），玉米产量与玉米占地面积比例呈正相关（ｒ＝０．７３）。据此，建立回归方程ＹＺ＝３９９．５０＋０，８５Ｘ和Ｙｙ＝－６．４９＋１５５９．５４Ｘ，预测宁夏引黄灌区小麦套种玉米“吨粮田”产量构成，玉米产量应为７０６．４７ｋｇ／ｍｕ，其占地面积为４５．７２％依不同带型作物产量和生育状况分析，处理Ｃ（小麦带宽１．２０ｍ，玉米带宽０．９０ｍ，下同），处理Ｇ（０．７０ｍ，０．５０ｍ）和处理Ｅ（１．２０ｍ，０．６０ｍ）为较佳带型。
In this paper, different types of wheat intercropping maize experimental study showed that intercropping crop production and corn yield was highly correlated (r = 0.94), corn yield and corn area ratio was positively correlated (r = 0.73) . Based on this, the regression equations YZ = 399.50 + 0,85X and Yy = -6.49 + 1559.54X were established to predict the grain yield of wheat intercropping corn in Ningxia Yellow River irrigated area. The yield of maize should be 706.47kg / mu The land area was 45.72%. According to the analysis of yield and reproduction status of different belt type crops, C (0.70m, 0.50m) and Treatment E (1.20m, 0.60m) is the preferred belt type.
