摘要
[目的]筛选最佳修剪叶幕厚度.[方法]以巨峰葡萄为试材,研究机械修剪的工作效率及4种叶幕厚度(30、40、50、60 cm)对葡萄生长、果实品质的影响.[结果]随着叶幕厚度增加,葡萄枝条节间变细变长,叶面积减小,叶绿素含量降低,果穗质量、果粒质量、果实纵横径减小,果实可溶性固形物含量下降;采用机械修剪比常规夏季修剪方式省工约57.69%,显著提高了工作效率.[结论]40 cm为最佳修剪叶幕厚度.
Abstract
[Objective]To screen the optimum canopy thickness.[Method]Taking Kyoho grape as the experimental material, the work efficiency of mechanical pruning,and the effect of mechanical pruning with different canopy thicknesses of 30, 40, 50, 60 cm on growth and fruit qualities were researched.[Result]The increasing canopy thicknesses made the shoot thin and longer, increased leaf area, lowered leaf chlorophyll content, which also decreased the panicle and single fruit weight ,the length and diameter of berry and soluble solids content.Mechanical pruning can save work than normal summer pruning way about 57.69% and dramatically improve work efficiency.[Conclusion]40 cm was the best canopy thicknesses.
