摘　　要：[目的]分析鲁东地区花生空秕原因。[方法]通过全面测定和调查花生常规地块和空秕发生地块的土壤pH、养分含量等指标及种植制度,明确造成鲁东地区花生空秕原因和空秕植株的特征特性。[结果]土壤酸化和缺钙是造成花生空秕的主要原因,连作较轮作更容易产生空秕,而花生与禾本科作物轮作较果树苗木间套轮作更容易避免空秕现象的发生。空秕植株较正常植株主茎高变高、侧枝变长、分枝数和主茎绿叶数增加,发生空秕的荚果较正常荚果粗糙,果皮变厚。[结论]该研究明确了花生空秕原因及空秕植株特征特性,可以为花生生产提供服务。[ Objective ] To analyze the cause leading to blighted peanuts in Eastern Shandong. [ Method ] The research mainly studied the farming system, soil pH, soil nutrient content in conventional plots and blighted peanuts plots,in order to find the cause of blighted peanuts and the char- acteristics of blighted peanuts in Eastern Shangdong. [ Result] Soil acidification and calcium deficiency were the major causes of blighted peanuts. Continuous cropping was easier to generate blighted peanuts than crop rotation,rotation of peanut and germanous crop were more likely to avoid empty pods phenomenon than rotation of peanut and fruit trees. The main stem height of blighted peanuts got higher and branch length got longer, at the same time, the number of branch and greenery increased. In addition, the pod of blighted peanuts was rougher and peel was thinner than the normal. [ Conclusion] The study identified the causes of blighted peanut and the characteristic of the blighted plant, which can provide service for the peanut production.
