当前,我县小麦产量由中产向高产迈进,1997年全县10万hm2小麦平均产量达到5580kg/hm2,其中6.67万hm2产量在6000kg/hm2以上。随着产量水平的提高,麦田群体大、个体弱、田间荫蔽、中下部通风透光不良,出现早衰或倒伏,降低穗重而减产问题日渐突出。因此,我们进行了小麦不同种植方式 At present, the output of wheat in our county moves from middle-level to high-output. In 1997, the average output of 100,000 hectares of wheat in the county reached 5580kg / hm2, of which 667,000 hm2 was above 6,000kg / hm2.
