- 摘要:
- 以9年生梨枣树(Ziziphus jujube Mill.）为试材，在无灌溉条件下，通过2种旱作管理技术处理，研究节水型修剪技术和竹节式聚水沟技术对梨枣枣吊、坐果及产量的影响。结果表明：节水型修剪技术与竹节式聚水沟技术的单独及联合实施，均提高了结果枣吊数量及枣吊的坐果能力，提高梨枣的产量；与对照相比，节水型修剪技术（HL）可提高产量83.14%，竹节式聚水沟技术(CJ)可提高产量38.44%，节水型修剪技术+竹节式聚水沟技术（HJ）效果最好，产量可提高155.00%。研究认为，在旱地无灌溉条件下的陕北黄土丘陵区应该以节水型修剪为主，最好结合节水型修剪在林下采用聚水沟措施。
- Abstract:
- Under the condition of non-irrigation，taking the 9-year-old pear jujube (Ziziphus jujube Mill.) trees which grafted on wild jujube (Ziziphus jujube Mill.var.spinosa (Bunge) Hu ex H.F.Chow.) as test material，different dry farming technologies were set，which included water saving type pruning technology，bamboo type poly ditch technology，and the different effects of each treatment on pear jujube fruitful bearing branchlet，fruit setting and yield were compared.The results showed that water saving pruning and bamboo type contour ditch，either singly or in combination，could increase significantly the number of fruitful bearing branchlet，fruit setting and yield.Compared with the control，water saving pruning (HL) could raise the yield by 83.14%，and bamboo type poly ditch (CJ) could raise by 38.44%，while the treatment (HJ)，combining the HL and CJ technologies，harvested the most and the yield by 155.00% of the control.In Loess Hilly Regions in Northern Shaanxi，under the condition of nonirrigation，the saving water pruning technology could play a main positive role in raising pear jujube yield，especially combining the bamboo type contour ditch technology.
