无棣县枣树栽培历史悠久,全县现有金丝小枣园6 720 hm~2,仅树龄80年以上的低产园就有840 hm~2。由于树龄偏大、管理不善等原因,造成树冠逐渐缩小、稀疏、树冠内出现大量枯死枝、生长势转弱、产量明显下降,甚至没有产量。为此我们于2014-2016年进行了低产金丝小枣园更新复壮技术研究,取得了较好效果。试验点的枣树平均株产增产明显,3年平均株产8 kg,比试验前增产142.4%。试验点的枣树树势有了 Jujube jujube cultivation has a long history, the county existing Ziziphus jujuba Park 6 720 hm ~ 2, only the age of 80 years or more in low-yielding garden have 840 hm ~ 2. As the age is too large, poor management and other reasons, resulting in canopy shrinking, sparse, a large number of dead branches within the crown, the growth potential of weakening, the output decreased significantly, or even no output. To this end, we conducted a research on the regeneration and rejuvenation of low-yielding golden jujube gardens in 2014-2016 and achieved good results. The average yield of jujube in the experimental site was significantly increased, with an average yield of 8 kg in 3 years and an increase of 142.4% compared with that before the test. Jujube tree test point with the potential
