冬小麦是我省主要夏收粮食作物。建国后发展较快,特别是七十年代以来,面积、单产、总产均有较大增长,但问题是:①没有合理的明确品种布局类型区,加以不看条件追求高产,使半冬性品种北移,招致冻害减产;②面积扩大与自然资源、生产条件不相适应,产量不稳;③夏、秋粮之间,粮食与经济作物之间比例失调,造成土壤“超载”,肥力下降,增产不增收;④“三夏”、“三秋”农活紧张,造成管理粗放。因此,搞好小麦生产布局,对协调几方面的关系是 Winter wheat is the main summer harvest food crops in our province. Since the founding of the People’s Republic of China, the development has been rapid. Especially since the 1970s, the area, yield and total output have witnessed significant growth. However, the problems are as follows: ① There is no reasonable and clear type of layout area, (2) the varieties moved northwards, leading to the frost damage reduction; (2) the expansion of the area was incompatible with the natural resources and production conditions, and the yield was unstable; (3) the imbalance between the grain crops and the cash crops in summer and autumn resulted in soil “overloading” Increase production does not increase; ④ “three summer”, “three autumn” agricultural work tension, resulting in extensive management. Therefore, to improve the layout of wheat production, the coordination of several aspects of the relationship is
