不同处理方法对温州蜜柑保果效应的研究

EFFECTS OF DIFFERENT TREATMENTS ON FRUIT RETENTION IN SATSUMA MANDARIN

以10年生枳砧温州蜜柑(宫川)为试材,在谢花前后采用抹春梢、环剥后包膜与不包膜、环割,环缢等方法保果。结果表明,各种方法均有保果效应,以抹春梢、环剥后包膜的保果效应最显着;环肃后包膜可促进愈合组织的形成,既促进了着果,又不削弱树势;各处理的树体内总糖含量与着果率呈正相关。

In order to study the fruit retention in ten-year-age Satsuma mand-arin with trifoliate orange stock (miyagawa), the following treatments of erasingspring shoots, ring-barking with and without plastic enveloping after treatments,ring-cutting and ring-banding were adopted. The results showed that all treat-ments had effect on fruit retention, of which the erasing spring shoots andring-barking with plastic enveloping had the best effect on fruit retention. Thetreatment of ring-barking with plastic enveloping could promote the woundedtissue formation without weakening the tree vigour. The fruit-setting percentagehas positive correlation with the total sugar in treated trees.
