摘　　要：为探究调环酸钙对冬枣生长及果实品质的影响,以3年生冬枣为试材,于枝条萌动时,间隔10 d连续叶面喷施不同浓度调环酸钙可湿性粉剂2次,浓度分别为300、500、700、900、1100倍液,以同期喷施500倍液烯效唑可湿性粉剂和清水作为对照。5月底定株观测植株新梢枝条数量、长度、粗度、叶片长宽、SPAD值等指标,果实着色后测定果实硬度、可溶性固形物含量、可滴定酸含量等品质指标。结果表明,叶面喷施调环酸钙能够有效抑制冬枣侧枝新梢萌发数量,其中500倍液对侧枝新梢萌发数量抑制效果最显著;喷施调环酸钙500倍液、700倍液对新梢长度、粗度及节间数的抑制效果显著;喷施调环酸钙500倍液能显著增加冬枣果实单果质量和可溶性固形物含量。因此,结合当地冬枣生产实际,在新梢萌芽初期叶面喷施调环酸钙700~900倍液1次,间隔10 d再喷1次,可以有效控制营养生长,提升果实品质,增加果农经济效益。In order to investigate the effect of prohexadione-calcium on the growth and fruit quality of winter jujube,3-year-old winter jujube was used as the test material.During the sprouting of branches,different concentrations of prohexadione-calcium wettable powder were sprayed twice on the leaf surface at intervals of 10 days,with concentrations of 300,500,700,900 and 1100 times,respectively.Meanwhile,500 times liquid of imidazole wettable powder and water were sprayed simultaneously as controls.At the end of May,the number,length,roughness,leaf length and width,SPAD value and other indicators of new shoots and branches of plants were observed and planted.Quality indicators such as fruit hardness,soluble solid content,and titratable acid content were measured after fruit coloring.The results showed that foliar spraying of prohexadione-calcium could effectively inhibit the number of new shoots sprouting on the lateral branches of winter jujube,with 500 fold solution having the most significant inhibitory effect on the number of new shoots sprouting on the lateral branches.The inhibitory effects of spraying 500 fold and 700 fold prohexadione-calcium solution on the length,roughness,and number of internodes of new shoots are significant.Spraying 500 times prohexadione-calcium solution significantly increased the single fruit weight and soluble solid content of winter jujube fruit.Therefore,in combination with the actual production of local winter jujube,spraying 700 to 900 times prohexadione-calcium solution on the leaves during the early sprouting stage of new shoots,and spraying again every 10 days,could control nutrient growth,improve fruit quality,and increase the economic benefits of fruit farmers.
