摘　　要：[目的]研究氰氨化钙不同施用量对桃树产量和品质的影响。[方法]以绿化9号为供试材料,研究氰氨化钙不同施肥量对桃树营养生长、产量和品质的影响。[结果]桃树施用氰氨化钙能明显增加根系数量、叶片面积和叶片厚度,显著提高叶绿素含量,增加桃产量,改善桃品质。盛果期桃树每棵施用氰氨化钙250g,0～40cm土层根系数量较CK增加41.94%,叶片厚度增加25.63%,叶绿素含量提高25.33%,单果重提高20.5%,单株产量增加21.6%,硬度提高12.5%,可溶性固形物增加13.2%。[Objective] The research aimed to study the influences of calcium cyanamide concentration on yield and quality of peach.[Method] With Lvhua9 as tested materials,the effects of calcium cyanamide concentration on vegetative growth,yield and quality of peach were studied.[Result] Using calcium cyanamide on peach obviously increased the number of root,the leaf area and the leaf thickness,and the chlorophyll content increased significantly,which improved the production and quality of peach.Using calcium cyanamide with 250 g per plant in the period of full fruits,compared with the control the number of root in depth 0-40 cm increased 41.94%,the leaf thickness increased 25.63%,the chlorophyll content raised 25.33%,the single fruit weight improved 20.5%,yield per plant increased 21.6%,the rigidity increased 12.5% and the soluble solids increased 13.2%.[Conclusion] The optimum application of calcium cyanamide on peach in the period of full fruits was 250 g per plant.
