　　作為水果中的神話，龍眼可謂是牛掰了。鮮龍眼吃起來(lái)甜美可口，還可以曬干制成龍眼干，作為保健藥材使用，這也讓很多果農(nóng)們對(duì)龍眼的種植青睞有佳!那么種植一顆龍眼樹(shù)需要多久開(kāi)花呢?龍眼樹(shù)什么時(shí)候結(jié)果?下面果果就帶領(lǐng)大家來(lái)了解一下吧!

　　龍眼樹(shù)什么時(shí)候結(jié)果

　　成熟的龍眼樹(shù)什么時(shí)候結(jié)果
龍眼樹(shù)什么時(shí)候結(jié)果 龍眼樹(shù)種多久開(kāi)花結(jié)果

　　3--4月開(kāi)花，5月下旬至8月底為龍眼結(jié)果和果實(shí)生長(zhǎng)期。7～8月果實(shí)成熟呈黃褐色時(shí)采摘。為無(wú)患子科植物，果供生食或加工成干制品，肉、核、皮及根均可作藥用。原產(chǎn)于中國(guó)南部及西南部，世界上有多個(gè)國(guó)家和地區(qū)栽培龍眼，如：中國(guó)，泰國(guó)、印度尼西亞、澳大利亞的昆士蘭州、美國(guó)的夏威夷州和佛羅里達(dá)州等。

龍眼樹(shù)什么時(shí)候結(jié)果 龍眼樹(shù)種多久開(kāi)花結(jié)果

　　龍眼定植后,經(jīng)過(guò)3-4年的正常栽培管理,已基本形成了早結(jié)豐產(chǎn)的樹(shù)冠和發(fā)達(dá)的根系,具備了開(kāi)花結(jié)果的營(yíng)養(yǎng)物質(zhì)條件,開(kāi)始進(jìn)入低齡結(jié)果階段。龍眼樹(shù)一般能活幾十年，果農(nóng)種的話果齡高峰期一過(guò)就不要了。

　　龍眼樹(shù)的生長(zhǎng)習(xí)性

　　龍眼是亞熱帶果樹(shù)，喜高溫多濕，溫度是影響其生長(zhǎng)、結(jié)實(shí)的主要因素，一般年平均溫度超過(guò)20℃的地方，均能使龍眼生長(zhǎng)發(fā)育良好。耐旱、耐酸、耐瘠、忌浸，在紅壤丘陵地、旱平地生長(zhǎng)良好，栽培容易，壽命長(zhǎng)，產(chǎn)量高，經(jīng)濟(jì)收益大，群眾喜種植。

　　龍眼樹(shù)如何過(guò)冬

龍眼樹(shù)什么時(shí)候結(jié)果 龍眼樹(shù)種多久開(kāi)花結(jié)果

　　冬季氣溫逐漸下降，龍眼樹(shù)在越冬期間，需進(jìn)入相對(duì)休眠，營(yíng)養(yǎng)生長(zhǎng)暫緩和停止，累積充足有機(jī)營(yíng)養(yǎng)，內(nèi)源激素活動(dòng)，促進(jìn)花芽開(kāi)始生理分化，是翌年早結(jié)豐產(chǎn)的重要環(huán)節(jié)。因此，龍眼園冬季管理應(yīng)引起重視。

　　1、加強(qiáng)冬季低產(chǎn)果園改造

　　冬季是低產(chǎn)龍眼改造的好時(shí)機(jī)，可利用冬閑勞力，開(kāi)展果園基礎(chǔ)建設(shè)，修整果園梯壁、園埂，清理排、灌水溝，興修水利及水土保持工程。作好擴(kuò)穴、增施遲效性農(nóng)家肥改良土壤或客土培土等工作，提高土壤肥力。

　　2、開(kāi)展冬季清園工作

　　冬季低溫，病蟲(chóng)都處于不活躍的弱勢(shì)。因此，應(yīng)趁機(jī)搞好清園工作，剪除龍眼樹(shù)上的病蟲(chóng)枝、交叉杖、蔭蔽枝、枯枝，集申燒毀。

　　3、控制龍眼冬梢

　　近年來(lái)，因氣候變暖，出現(xiàn)暖冬現(xiàn)象，引發(fā)龍眼冬梢抽生，消耗龍眼樹(shù)體營(yíng)養(yǎng)成份，不利花芽分化。

　　龍眼樹(shù)的防凍措施

龍眼樹(shù)什么時(shí)候結(jié)果 龍眼樹(shù)種多久開(kāi)花結(jié)果

　　龍眼樹(shù)喜溫忌凍，正常年份我市龍眼都可安全越冬，但遇個(gè)別年份，寒流襲擊，在低洼地、沿海沙質(zhì)地的龍眼園會(huì)造成凍窖，特別是幼齡樹(shù)，應(yīng)引起警惕。防寒防凍方法：在樹(shù)體基部培土，樹(shù)干刷白，用稻草、薄膜包扎、覆蓋樹(shù)冠，增施火燒土等熱性肥料，使植株健壯，增疆抗寒能力，在霜凍來(lái)臨前采取灌溉、噴水、熏煙等防凍措施。

　　種植龍眼樹(shù)收益還是不錯(cuò)的，但是龍眼樹(shù)要防寒防凍，龍眼樹(shù)喜溫，一般龍眼都種植與熱帶!了解完龍眼樹(shù)什么時(shí)候結(jié)果，猜您還想知道：
