“麦玉苕”是我省丘陵区的主要复种轮作方式。近年来,小麦预留行里间作早熟大麦,既增加小春粮食收入,又利于大春玉米早播早收和玉米红苕高产,是一种值得大力发展的间作方式。但是,现有用于间作的早熟大麦品种植株较高,容易倒伏,影响小麦的生长发育和本身产量潜力的发挥,限制了大小麦间作方式的发展,不利于我省粮食生产的进一步提高。多效唑对多种作物具有延缓生长,促进分蘖,抑制节间伸长,提高产量等作用。缩节胺对棉花等作物具有抑制生
“Mai Yu 苕” is the main crop rotation in the hilly areas of our province. In recent years, wheat reserve in the middle of the barley for early maturity, not only increase the spring grain income, but also conducive to early spring sowing spring corn and corn high yield, is a worthwhile development of intercropping. However, the existing early-maturing barley varieties used for intercropping have higher plants and easily lopsided, which affects the growth and development of wheat and the potential of its own yield, restricting the development of wheat-wheat intercropping and is not conducive to the further improvement of grain production in our province. PP333 can retard the growth of many crops, promote tillering, inhibit internode elongation and increase yield. Reduced amines inhibit cotton and other crops
