1 选用高抗旱品种早熟品种比晚熟品种躲过生长后期干旱的机率要大的多,因此可以考虑选用早熟品种。然而,早熟毕竟只是适应干旱环境的一个重要性状,而具有能在不同水分状况、不同田块和不同年份均表优良特性的抗旱品种才是稳产、高产的品种,如山东省农业科学院玉米研究所培育的鲁单9002等。
1 The selection of early-maturing varieties with high drought-resistant varieties is much more likely to evade late-stage drought than that of late-maturing varieties, so early maturing varieties can be considered. However, precocious puberty, after all, is only an important trait adapted to the arid environment. However, drought-resistant cultivars that have excellent characteristics in different water conditions, plots and years have been stable and high-yielding varieties such as Maize Research Institute of Shandong Academy of Agricultural Sciences Cultivation of Ludan 9002 and so on.
