地膜穴播条件下冬小麦品种的南种北用试验

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％。

A Study on Making Use of Southern Winter Wheat Variety in North under Cultivation of Film-mulching and Bunch-seeding

In 1997～1998,technology of film-mulching and bunch-seeding was used to study semiwinter wheat adaptability in Jinzhong region. The results indicated that when south wheat variety was planted in the north, its plant height is universally over 25cm lower, No of grains/ear and weight/ 1 000 grain of most growing wheat are all higher than ck, and southern good strains of seeds Jinmai 47 was selected. Its yield was prominently higher than Jinmai 51 and Jinmai 43, and the increment rate was 22.2% ～ 34.0% .
