1.结果母枝剪留长度:通常按留芽多少可将枝条分成短梢(1—3芽)、中梢(4—7芽)、长梢(8—12芽),具体修剪留梢长度,根据架式、棚驾、树形、品种、特性、肥水条件而定。目前多采用混合修剪,葡萄生长势旺,以长梢修剪为主;生产势弱,以中短梢修剪为主;同一品种,枝蔓壮多留几节,枝蔓瘦弱则少留些。2.留芽量:留芽量要适当,若留架芽量多,则新梢多导致营养不良,直接影响结果。葡萄应兼顾产量和质量并应考虑维护树体以利多产效益,所以不可追求过高产量,亩产控制在1000至1200公斤为宜,如果棚架上每平方米留梢10—15个,宜每平方米留芽20—30个。
1. Results The length of the branch cuttings: usually divided by the number of buds can be divided into shoots short shoots (1-3 buds), the shoots (4-7 buds), long shoots (8-12 buds), the specific length of the pruning shoot , According to frame, shed driving, tree, variety, characteristics, fertilizer and water conditions may be. The current use of mixed pruning, vigorous growth of grapes to long-pruning-based; weak production, mainly in the short shoot pruning; 2 to leave the amount of buds: the amount of buds should be appropriate to stay, if the amount of buds to stay more, the new shoots lead to malnutrition, a direct impact on the results. Grapes should take into account the yield and quality and should consider the maintenance of trees to facilitate the productive benefits, it can not be pursued too much output, the control of 1000 to 1200 kg per mu is appropriate, if per scaffolding stay per square meter 10-15, should Budding 20-30 per square meter.
