摘　　要：基于沿海旱砂地土壤肥力特征及花生养分需求规律,研制防治花生空秕的含钙专用肥、钙质物料及含钙有机肥等。通过田间试验,研究不同含钙肥料对花生农艺性状、土壤化学性状、产量及品质的影响,结果表明,施用不同含钙肥料均有利于降低空秕率,提高土壤pH、交换性Ca2+含量和Ca饱和度,增加产量,改善花生品质,并以施用含钙花生专用肥(975kg/hm2)+含钙有机肥(3000kg/hm2)效果较好。Following the fertility character of coastal drought sand and nutrient requirement characteristics,the calcium special fertilizer,calcium material and calcium organic fertilizer were developed to prevent sterile pod of peanut.By field experiment,the effect of calcium fertilizers on chemical characters of soil,agronomic characters,yield and quality of peanut was studies.The results showed it could prevent sterile pod of peanut,improve the soil pH,exchangeable calcium and calcium saturation,increase the yield of peanut,improve the quality of peanut by applying the different calcium fertilizers.The best effect was the treatment of the calcium special fertilizer（975kg/hm2） ＋ the calcium organic fertilizer（3000kg/hm2）.
