1992—1993年度小麦生育期间,河南省的气候特点既有有利于小麦生产的方面,也有不利于小麦生产的方面,总的讲无大的自然灾害发生,且病虫害发生较轻。在领导重视,群众努力,气候有利,品种利用相对合理的共同作用下,小麦又获丰收。但从大面积生产情况看,小麦品种的抗病、抗冻、抗干热风等抗逆力没有得到充分考验,目前推广的多数品种均表现不错,品种间没确大的差异。因此在当前小麦品种利用中,特别是对一些新品种的宣传,又出现丁各吹各的号的现象,“高粱玉米麦、咸阳大穗麦”等也在广告中不断出现,易给生产上造成无所适从的局面。如何正确认识和评价大面积生产 During the period of wheat growth in 1992-1993, the climate characteristics of Henan Province are not only beneficial to wheat production, but also unfavorable to wheat production. Generally speaking, no major natural disasters occur and pests and diseases occur less. In the leadership of attention, the masses work hard, climate is favorable, the use of varieties of the relative reasonable under the common action, the wheat bumper harvest. However, from the perspective of large-scale production, the resistance of wheat cultivars to disease resistance, frost resistance and anti-dry-hot air have not been fully tested. Most of the varieties currently promoted have performed well with no significant differences among varieties. Therefore, in the current use of wheat varieties, especially for some new varieties of publicity, there are the phenomenon of Ding Blowing the number of “sorghum corn, Xianyang big spike wheat” are also constantly appear in the ad, easy to produce Resulting in a loss of situation.
