试验比较了盛果期灰枣树对不同修剪方法的反应。结果表明,枣树连年修剪,根的数量、冠幅、干周均大于(牙刂)枣处理树。萌发枣头的数量、质量和抽生有效枣拐的数量等也表现出相似的结果。修剪树有效枣股数多于(牙刂)枣树,差异显著;百果鲜重较(牙刂)枣处理多40.1g,单株产量提高15.3%。叶片总糖和全氮测定结果:修剪处理在6月下旬含量较高,此时正值枣吊、枣头生长,花芽分化,开花和幼果发育的关键时期,这对树体的生长发育和产量提高都起到良好的作用;其次,修剪与环切结合的效果优于修剪+(牙刂)枣,但次于修剪处理。
The experiment compares the response of jujube tree to different pruning methods. The results showed that jujube tree pruning year after year, the number of roots, crown width, dry weeks are greater than (Teeth) jujube tree. The number of germinated jujube heads, the quality and the number of jujube shives that have been drained, also showed similar results. Pruning tree effective jujube shares more than (Teeth) jujube tree, the difference was significant; fresh fruit weight more than (Teeth) jujube treatment 40.1g, yield per plant increased 15.3%. Results of total sugar and total nitrogen in leaves: The content of pruning was higher in late June, which was the critical period for the growth of jujube, jujube head, flower bud differentiation, flowering and young fruit development. Yield increase have played a good role; Second, the combination of trimming and circumcision effect is better than pruning + (Teeth) jujube, but second to pruning.
