摘要
以3年生"玫瑰香"葡萄为试材,设置了修剪间隔为10、15、20、30d4个处理,对葡萄新梢生长、叶绿素含量、干物质含量、养分含量、果实品质进行了测定,以探讨"玫瑰香"葡萄模式化修剪对其植株生长和果实品质的影响。结果表明:模式化修剪对新梢生长有显著的影响;20d修剪1次处理的叶绿素含量一直保持较高的水平,处理60d后叶绿素含量为1.53mg/g;10d修剪1次处理的干物质含量最高,为55.69%;修剪处理对枝条中氮和蛋白质含量的影响不显著,但钾含量均显著高于对照;模式化修剪对葡萄的果实大小、色泽影响不显著,但总糖含量显著提高;综合评价,20d修剪1次的处理效果最适合Y型架。
Taking 3-year-old ‘ Muscat Hamburg' grape as materials, 4 pruning interval treatments of 10 d, 15 d, 20 d and 30 d were set for the test. Shoot increment, chlorophyll, dry matter,nutrient and fruit quality of ‘Muscat Hamburg' grape were determined,in order to investigate the pattern pruning effect on growth and fruit quality. The results showed that pattern pruning had significant effect on the growth of shoots. Chlorophyll content of 20 d pruning treatment had maintained a high level,and chlorophyll content of 60 d after the treatment was 1.53 mg/g. Dry matter content of pruning after 10 d was the highest,it was 55.69%. The effect of pruning on nitrogen and protein in shoot was not significant,but potassium content was significantly higher than that of the control. The effect of pattern pruning on grape's size and color was not significantly,and total sugar content increased significantly. Comprehensive evaluation of all aspects, the treatment of 20 d was the most suitable for Y type rack.
