- 摘要:
- 以“丽江雪桃”为试材，研究比较了长果枝、中果枝、短果枝3种不同的冬季枝条修剪方式对桃树体总糖、粗蛋白、粗脂肪含量及对新梢生长发育的影响。结果表明：长枝修剪后的枝条中总糖含量、粗蛋白含量、粗脂肪含量均高于其它几种修剪方式，长果枝修剪后，1 a生枝抽生新梢发生数量和生长量的能力比中果枝修剪和短果枝修剪后的强；而短果枝修剪的果树抽生的新梢平均长度、最长新梢长度以及全树新梢总长则显著好于长、中果枝修剪方式，说明冬季修剪是一项重要的管理技术。
- Abstract:
- With ‘Lijiang’ peach as material，the effect of 3 different winter pruning methods (long bearing shoot，medium bearing shoot and short bearing shoot) on the total sugar content，crude protein content，crude fat content and the growth and development of new shoot were studied and compared.The results showed that the total sugar content，crude protein content and crude fat content in branch after long bearing shoot pruning were higher than the others.The ability of the number and growth of shoots sprouted from 1 year old branch were stronger than the other two methods.The average length of new branch，the length of the longest branch and the total length of the new branches were significantly better than the other two pruning methods.It proved that winter pruning was an important management technique.
