摘　　要：以6年生‘绿化9号’桃为试验材料,采用环状沟施的方式施用4种不同浓度的氰氨化钙,研究其对桃树生长发育、产量及土壤理化性状的影响。结果表明,不同浓度的氰氨化钙处理能显著改善桃园土壤理化性状,使土壤容重降低8.72%~12.75%,土壤孔隙度、有机质含量和pH值均有不同程度的增加;显著提高土壤中有效氮、磷、钾、钙等元素含量,最高较对照增加20.40%、25.50%、27.30%和11.57%,有效铜含量下降50%以上;促进桃树生长,使侧根数量、新梢数量、叶片厚度和相对叶绿素含量显著增加;单株产量升高,果实可溶性固形物含量升高10%以上。综合分析,氰氨化钙处理以浓度250 g/株为宜,可在桃树上推广应用。The six-year-old‘Lvhua No.9’peach was used as the material,four treatments with different concentrations of calcium cyanamide were set up in the way of circular ditch application.The effects of different concentrations of calcium cyanamide on peach growth,yield,quality,soil physical and chemical properties were studied.The results showed that different concentrations of calcium cyanamide significantly improved the physical and chemical properties of peach orchard soil.Soil porosity,organic matter and pH increased,while soil bulk density decreased by 8.72%-12.75%.The contents of nitrogen,phosphorus,potassium,calcium and other elements in soil were significantly increased,the highest increase compared to the control was 20.40%,25.50%,27.30%,and 11.57%.While the content of available copper was reduced more than 50%.The number of lateral roots,new shoots,leaf thickness and chlorophyll content increased significantly.The yield per plant increased,soluble solid content of quality indexes increased more than 10%.Through comprehensive analysis,the optimum concentration of calcium cyanamide treatment was 250 g/plant,which could be popularized and applied in peach trees.
