摘 要：
为充分掌握和合理应用驿新圆大枣在花蕾开花不同时期最佳的环剥宽度,以10~12a生的驿新圆大枣为试材,进行了不同环剥时期、环剥宽度试验,结果表明:驿新圆大枣花蕾50%左右开花时进行0.5cm宽度的环剥产量最高,达33.114 0t/hm~2;与花蕾开花70%左右时采用0.5cm宽度环剥,花蕾开花50%左右时采用0.4cm、0.6cm宽度环剥和花蕾开花30%左右时采用0.5cm宽度环剥的相比,产量分别提高6.9%、12.4%、15.4%和17.8%;花蕾开花50%左右采用0.5cm宽度环剥,与其他4种处理之间在产量上存在极显著差异。

摘 要：
In order to get and use the best girdling width of Yixinyuan jujube flower bud at different blooming stages,10 to 12year-old Yixinyuan jujube trees were selected as the experimental material,and the girdling width experiment was taken at different blooming stages of flower buds.The results showed that the Yixinyuan jujube trees with the flowering rate of 50% and girdling width of 0.5cm had the highest fruit yield,which was 33.114 0t/hm~2.Compared with the treatments of girdling width of 0.5cm when the flowering rate was 70%,girdling width of 0.4cm when the flowering rate was 50%,girdling width of0.6cm when the flowering rate was 50%,and girdling width of 0.5cm when the flowering rate was 30%,the highest yield increased by 6.9%,12.4%,15.4% and 17.8%,respectively.As a result,there were extremely significant differences between the girdling width of 0.5cm when the flowering rate was 50% and the other four treatments.
