通过九个试验点的试验结果表明,本试验设计的“一间二”、“二间二”、“二间三”、“二间四”等四种玉米大豆间作方式均比对照增产,尤其是大豆增产显著。试验结果还表明,无前作的空地可采用“一间二”、“二间二”和“二间三”三种方式中的任何一种;有前作的土地可根据前作的行、幅宽度选用“一间二”或“二间二”;在土壤肥力低的下等地,采用“二间四”,既可多得大豆,又不影响玉米的收益。 The results from the nine test points show that the four kinds of soybean intercropping methods such as “one two”, “two two”, “two three” and “two four” Is a significant increase in soybean. The test results also show that no pre-open space can be used “one two”, “two two” and “two three” in any one of three ways; pre-made land according to the previous line, width selection “One in two” or “two in two”; in the lower soil fertility, the use of “two four” can not only increase the yield of soybean, but also does not affect the corn.
