扩大灌溉面积是发展农业的重要措施之一。各小麦对灌水的反应是很敏感的,但不是所有的品种都能充分利用灌溉条件。在溉灌条件下高秆类型品种增产不甚明显,有时甚至比在旱地条件下减产。近来选种工作者育成一批矮秆小麦新品种,它们秆矮、抗倒,更适于水浇条件。 The expansion of irrigated area is one of the important measures to develop agriculture. The response of wheat to irrigation is sensitive, but not all species make the most of irrigation. Under irrigated conditions, the production of high-stalk type varieties is less pronounced, and sometimes even lower than in dryland conditions. Recently, breeders have bred a new crop of dwarf wheat, which is short in stalk and lodging resistant, and is more suitable for watering conditions.
