目前黄河流域冬麦区(北方冬麦区)的小麦产量最高,亩产千斤以上是常事,最高可达1800—2000斤,比长江流域冬麦区和西南冬麦区(南方冬麦区)的小麦产量高很多,南方冬麦区的农户对北方高产小麦非常心动,加上媒介对一些超高产北方品种的报道,南方冬麦区的农户更是跃跃欲试,大量引种,但结局大多不尽人意,部分更是颗粒无收。北麦南引存在许多误区:
At present, the winter wheat area in the Yellow River Basin (northern winter wheat area) has the highest yield of wheat, and it is common for more than one kilogram per mu to reach 1800-2000 kg, which is higher than that of the winter wheat area in the Yangtze River Basin and the winter wheat area in the southwest Far higher wheat output, farmers in the southern winter wheat area are very eager to produce high-yielding wheat in the north. Coupled with media reports of some ultra-high yielding northern cultivars, farmer households in the southern winter wheat region are eager to introduce large quantities, but the results are mostly unsatisfactory. Part of the crop is confiscated. North Mai Nan cited many errors:
