不同砧木对浙东海涂地红美人柑橘生长发育和果实品质的影响

Effects of different rootstocks on the growth and fruit quality of‘Hongmeiren’citrus on the coastal soil of Eastern Zhejiang

以红美人柑橘为试材,研究了7种砧木对柑橘生长发育和果实品质的影响,以期筛选出耐盐碱砧木,开展浙东地区海涂地红美人适栽砧木的运用推广。结果表明:资阳香橙砧的树高、冠幅、新梢长度及新梢粗度均最大;朱栾砧的单叶重、叶面积最大,其次为资阳香橙砧;朱栾砧和资阳香橙砧的叶片厚度最大;枳雀砧的可溶性固形物含量最高,但可滴定酸含量也最高;朱栾砧的可滴定酸含量最低,固酸比最高。综合树体生长量和果实品质,朱栾可以作为海涂地红美人栽培的优良砧木。

In order to screen out saline-alkali resistant rootstocks and promote the application of suitable rootstocks of‘Hongmeiren’citrus cultivated on the coastal soil,the effects of seven kinds rootstocks on the growth and fruit quality of‘Hongmeiren’citrus were studied in eastern Zhejiang.Among them,tree height,crown width,new shoot length and coarseness of‘Hongmeiren’citrus grafted on‘Ziyangxiangcheng’rootstock were the largest.‘Hongmeiren’citrus’s single leaf weight and area were the largest when grafted on‘Zhuluan’rootstock,followed by‘Ziyangxiangcheng’rootstock.In addition,‘Hongmeiren’citrus performed the thickest leaves when grafted on‘Zhuluan’rootstock and‘Ziyangxiangcheng’rootstock.The content of fruit soluble solid of‘Hongmeiren’citrus grafted on‘Zhique’rootstock is highest,however the titrable acid content was also the highest.The lowest titrable acid content and the highest solid acid ratio were found when grafted on‘Zhuluan’rootstock.Therefore,based on the analysis of tree growth and fruit quality,it is suggested that‘Zhuluan’rootstock is an excellent rootstock for‘Hongmeiren’cultivated on the coastal soil of eastern Zhejiang.
