过去的研究指出,冬小麦在不同的生长阶段,对水应力(water stress)是敏感的。而现在的试验证明,如果在冬小麦播种期间土壤贮水量适当的话,那么,在其各个生长阶段抑制灌溉水,都不会影响谷物的产量。 在美国科罗拉多州阿克伦中央大平原研究...过去的研究指出,冬小麦在不同的生长阶段,对水应力(water stress)是敏感的。而现在的试验证明,如果在冬小麦播种期间土壤贮水量适当的话,那么,在其各个生长阶段抑制灌溉水,都不会影响谷物的产量。 在美国科罗拉多州阿克伦中央大平原研究站(The Central Great Plains Research Station)的一些研究中,ARS的农学家Bohn Dumbar和发展灌溉的管理专家R.Wayne Shawcroft,对冬小麦的春季生长阶段。展开更多
