临泽县1988年粮食单产达到617公斤,成为全国粮食高产县,1989年又获得自1983年以来的第7个丰收年,粮食单产达到628公斤,创历史最高水平。但是在高产地区并不都是高产区,也存在有相当部分的中低产田。为了挖掘生产潜力实现全面均衡增产,改造高产县中的中低产田势在必行。一、中低产田形成原因浅析在同一气候和耕作条件下,在一个区域内为什么会出现土壤生产力高低不平衡的差别,
Provisional grain yield in Linze County in 1988 reached 617 kilograms, making it the country with the highest grain yield in the country. In 1989, it was the 7th harvest year since 1983 with grain yield reaching 628 kilograms, the highest record in history. However, not all high-yielding areas are high-yielding areas, and there is also a considerable part of low-yielding fields. In order to tap the potential of production to achieve a comprehensive and balanced production increase, it is imperative to transform middle-low yield fields in the high-yielding counties. First, the formation of low-yield fields Analysis of the reasons for the same climate and farming conditions, why there will be an imbalance in the level of soil productivity,
