| 中文摘要: |
| 以“夏黑”葡萄为试材,通过花前两段摘心中第1段穗上不同留叶数处理,研究其对结果枝蔓、叶片、花穗、果实生长的影响。结果表明：花前两段摘心中以第1段穗上2叶重摘心最佳,处理时间4月1日-4月6日,结果枝叶片总数保留17片,顶端留1根二次副梢4叶重摘心,其后顶端副梢1叶反复轻摘心,至8月中旬后,顶端不留副梢技术模式。既降低结果枝的生长势,又保持结果枝足够总叶面积和花对叶大小,从而达到果实品质提升,增大花穗和花梗长度的目的。 |
| 英文摘要: |
| Taking "Summer Black" grape as test material, the effects of different leaf numbers on the growth of fruiting branches, leaves, flower spike and fruits were studied. The results showed that in the first two stages of top-cut, the heavy top-cut by two leaves above the spike during the first stage was the best. The treatment time was from April 1 to April 6. The total number of leaves on the fruiting branch was 17, keep only one secondary shoot at the top, heavy top-cut by four leaves, and then top-cut by one leaf repeatedly on the top secondary shoot. After mid August, all secondary shoot at the top should be removed. Thus not only reduce the growth potential of fruiting branches, but also maintain sufficient total leaf area and the size of leaf close to the fruiting branches, so as to improve fruit quality and increase the length of flower spike and stem. |
