不同修剪方法对沃柑幼树成形及早期产量的影响

Effects of Different Pruning Methods on the Formation and Early Production of Fertile Orange Saplings

[目的]研究不同修剪方法对沃柑幼树成形、早期产量的影响,为沃柑幼树修剪整形提供参考。[方法]对桂林市农业科学研究中心3年生枳砧沃柑进行春夏秋梢摘心以及留梢长30、20、15 cm短截整形修剪处理,记录新梢数、新梢长度、末级枝梢数、果实可溶性固形物含量、平均单果重和单株产量等。[结果]沃柑幼树不同修剪程度对其早期产量的影响表现为留梢30 cm短截>轻剪>留梢20 cm短截>留梢15 cm短截。留梢30 cm短截处理后的3年生沃柑株高173 cm、冠径146 cm(东西)×218 cm(南北),产量高达51180 kg/hm^(2)。[结论]以留梢30 cm短截处理效果最好,更有利于沃柑早期产量的提升,能有效提高橘园前期经济效益。

[Objective]The effects of different pruning methods on the formation,early yield and quality of fertile orange saplings were studied in order to provide reference for the pruning and shaping of fertile orange saplings.[Method]The three-year-old fertile orange in Guilin Agricultural Science Research Center was topped in spring,summer and autumn,and the length of 30,20,15 cm was short-cut,and the number of shoots,length of shoots,and ends were recorded.The number of branch shoots,fruit soluble solid content,average fruit weight and plant yield,etc.,were recorded.[Result]The effects of different pruning degrees on the early yield of fertile orange saplings were in the order of 30 cm short cut with top left>light pruning>20 cm short cut with top left>15 cm short cut with top left.The three-year-old fertile mandarin after the 30 cm short-cut treatment had a plant height of 173 cm,a crown diameter of 146 cm(east-west)×218 cm(north-south),and yield of 51180 kg/hm^(2).[Conclusion]The treatment effect of 30 cm short truncation was the best,which was more conducive to the improvement of the early yield of fertile orange,and could effectively improve the early economic benefits of orange orchards.
