摘　　要：以 6年生“贵农 5号”刺梨为材料 ,探索了更新修剪对树体的营养状况、枝梢生长和产量、品质的影响。结果表明 ,不同程度的回缩更新修剪 ,能够显著促进刺梨的新梢生长 ,增加新梢抽生数量 ,提高刺梨的产量和品质 ,增加刺梨新梢叶片的N、P、K、Zn等营养元素的含量 ,降低刺梨一年生休眠枝中N、P、K元素和淀粉、可溶性总糖含量 ,但对刺梨新梢叶中的Ca、Mg。Renewal pruning was used on 6 year old Rosa roxburghii Tratt cv.Guinong No.5 in order to study the effects of different renewal pruning levels on the nutrient status,shoot growth,yield and quality of the fruit in cili tree.The results showed that different levels of renewal pruning could promote effectively the shoot growth,increase the number of shoot,the yield and quality of fruit,and the contents of mineral nutrition N,P,K,Zn in shoot leaf of cili.It could also reduce the content of N,P,K,starch and water soluble sugar in annual dormant branch of the plant,but the contents of Ca,Mg,Fe in shoot and the contents of reducing sugar in annual dormant branch had no such changes.
