湖南省温州蜜柑栽培面积已达290多万亩,其中以尾张温州蜜柑居多。其生长快,发枝力强,封行早,平地亩栽60株约10年、亩栽80株7～8年就封行郁闭,树冠内膛光秃,平面结果,产量逐年下降。一般采用主枝轮换更新或露骨更新改造,但损失枝叶多,第一、二年将减产或无产。为此,我们进行了以扭枝曲枝为主,结合疏删短截更新改造封行桔园树形试验。初步结果表明,采用此技术,不仅使树形得以改造,而且更新当年仍能增产。
Satsuma Wenzhou, Hunan Province has reached more than 290 acres of cultivated area, of which the most tail mandarin orange. Its fast growth, strong twigs, seal line as early as 60 acres planted acres for about 10 years, planted acres of 80 7 to 8 years sealed the canopy closed, crown bore bare, flat results, the output decreased year by year. Generally use the main branch rotation update or explicit renewal transformation, but the loss of branches and leaves more, the first two years will cut or no production. To this end, we conducted a twisted twig-based, combined with sparse short cut update transformation of the Enclosure tree test. Preliminary results show that using this technology not only allows the tree to be rebuilt, but it can still increase production in the current year.
