１９９７～１９９８年，采用地膜穴播技术，对山西省南部麦区的半冬性小麦品种在晋中地区进行了适应性试验。结果表明，冬小麦品种南种北用，植株高度普遍降低２５ｃｍ以上，大多数供试品种穗粒数、千粒重都高于对照。并且初步筛选出了南部优良品种晋麦４７号，比对照晋麦５１号、晋麦４３号显著增产，增产幅度达２２２％～３４０％。 From 1997 to 1998, the semi-winter wheat varieties in the wheat-growing area of ​​southern Shanxi Province were tested in the Jinzhong area by using the technique of film-mulching. The results showed that the winter wheat cultivars were used southward and the plant height was generally reduced by more than 25cm. The grains per spike and 1000-grain weight of most of the tested cultivars were higher than those of the control. In addition, we screened out Jinmai 47, a fine variety in the south, which increased yield significantly by 222% -340% compared with Jinmai 51 and Jinmai 43.
