黄河三角洲小麦低产的原因及改进对策

Reasons for Low Yield of Wheat and Its Improving Countermeasures In Yellow River Delta

黄河三角洲土壤盐渍化影响小麦高产稳产。本文通过分析小麦低产的主要原因,并提出改进对策。通过培育并选用耐盐品种、以水调盐、合理施肥、覆盖压盐和适当深耕等技术的综合运用,可以显著减轻盐渍化对小麦生产的影响,改变该区域小麦产量低而不稳的局面。

The soil salinization of Yellow River Delta is the main factor to affect the yield of wheat. This paper analyzed the reasons for low yield of wheat and singled out the improving countermeasures. Using anti - saline cuhivars, reducing salinity by water management, applying fertilizer reasonably ,controlling the salinity by covered with plastic film or straw, and deep ploughing. By use these techniques, the effects of soil salinization on wheat could be reduced, and the situation with low and unstable wheat yield would be changed.
