生产实践表明,山西省北中部存在着程度不同的作物冷害,严重冷害年常造成作物产量大幅度下降。本文初步研究了该区冷害发生的时段、指标、类型分析了冷害的时空分布,有针对性的提出了可操作的防御与减轻冷害的措施建议。
Production practice shows that there are different degrees of cold damage in the central and northern parts of Shanxi Province, and serious chilling damage often leads to a sharp drop in crop yields. In this paper, the time, index and type of chilling damage were analyzed preliminarily. The spatial and temporal distribution of chilling damage was analyzed. Some suggestions were put forward to prevent and reduce chilling injury.
