龙眼是我国的名贵特产。目前龙眼结果大小年现象十分严重。“大年”结果的产量往往是“小年”结果产量的2～5倍,现就龙眼大小年结果原因及其克服途径,介绍如下。一、龙眼大小年结果的原因(一)龙眼夏梢抽生情况与开花结果的关系龙眼的夏梢和夏延秋梢是主要的结果母枝,夏梢抽生的数量和质量与次年开花结果的多少密切相关。龙眼新梢大多是从已充实的枝梢顶芽延生,也有从短截枝上的腋芽抽出。所以,肥水不足,管理不善,树势衰弱的龙眼逢“大年”开花结果多,任其开花结果,必然是养分
Longan is China's expensive specialty. Longan results of the current size of the year is very serious. The yield of the “big year” results is often 2 to 5 times the output of the “small year” result. The reasons for the longan size year results and the ways to overcome them are as follows. First, the size of the results of the longan size (a) the longan summer shoots the situation and flowering the relationship between the longan and the summer dwarf autumn tip is the main result of the mother branch, summer shoots the number and quality of the next flowering and flowering results The number of closely related. Longan shoots are mostly from the tip of the bud has been full of extension, but also from the axillary buds on the short branch out. Therefore, lack of fertilizer and water, poor management, frail long-term downturn in the “New Year” flowering more, let it flowering, must be nutrients
