以13年生的‘沾冬2号’冬枣树为试材,在减小环剥宽度的前提下,于行间或株间两侧距树干3倍胸径距离处,隔年轮换进行根系修剪并配施菌根菌剂,探讨根系修剪配施菌根菌剂对减轻冬枣环剥不利影响的作用。结果表明,与常规环剥相比,在减小环剥宽度条件下,根系修剪、根系修剪配施菌根菌剂处理减少了冬枣枣吊和花朵数量,提高了坐果率、叶片过氧化氢酶活性和产量,改善了叶片营养和果实品质,根系修剪配施菌根菌剂的总体效果好于单独根系修剪。综合来看,根系修剪配施菌根菌剂有利于减轻环剥伤害,促进树势的恢复和产量、品质的提高。
Taking 13-year-old ’Zhan-Dong No.2’ jujube tree as test material, under the premise of reducing the width of girdling, Root fungicides to explore the root pruning with mycorrhizal fungi to reduce the adverse effects of jujube ring stripping role. The results showed that compared with conventional circumcision, root pruning and root pruning with mycorrhizal fungi decreased the number of jujube hanging and flowers, increased fruit setting rate, leaf catalase Activity and yield, improve leaf nutrition and fruit quality, root pruning with mycorrhizal fungi agent overall effect is better than single root pruning. Taken together, root pruning with mycorrhizal inoculum is conducive to mitigate the circumcision damage, promote the recovery of tree vigor and the improvement of yield and quality.
