一、掌握脐橙特性 脐橙不同于温州蜜柑,除较不耐寒外,一般花量比温州蜜柑多十几倍,导致营养不足,树势衰弱,春梢发生量少,着果率低,到6月霉雨季节发生大量早夏梢,这些早夏梢第二年又大量着花、落花、落果,形成恶性循环。树势中庸而着花少的树,春梢有叶花比例高,花蕾脱落减少,反而结果率高,产量稳定。 脐橙着果位置,树冠内膛比外围高,所结的果实品质好。直立的长枝不着花,即使着花,所结的果实皮厚汁少,因而不能象温州蜜柑养成凹凸树冠。内部要有弱光,结果层要一定的受光量,副主枝间隔可少些,近
First, grasp the characteristics of navel Orange Navel orange is different from the Wenzhou, in addition to less cold, the general spend more than ten times more than the Wenzhou Satsuma, leading to lack of nutrition, tree weakness, spring shoots occur less fruit rate is low, to June A large number of summer rainy summer early summer shoots, these early summer shoots a large number of flowers, falling flowers, falling fruit, forming a vicious cycle. Tree moderate and less flowers trees, spring shoots have a high proportion of leaf flowers, buds off to reduce, but the result rate is high, the output is stable. Navel orange fruit position, crown crown than the outer high, the fruit of good quality. Upright long branches do not flower, even if the flower, the fruit of the skin thick jujube less, which can not be as concubine crown of Wenzhou Satsuma. Internal weak light, the results of the layer to a certain amount of light, Deputy main branch interval less
