批發(fā)供應(yīng)維多利亞葡萄苗金立葡萄果苗

 金華市金東區(qū)金立葡萄果苗基地專業(yè)培育各種葡萄果苗，品種有夏黑、金手指、巨玫瑰、美人指、甬優(yōu)一號(hào)、巨峰優(yōu)系、京亞、京玉、維多利亞、比昂扣、巨峰、醉金香等各種扦插苗和嫁接苗，竭誠(chéng)歡迎新老客戶光臨指導(dǎo)。交流合作。（一）溫度葡萄各種群在生長(zhǎng)各個(gè)時(shí)期對(duì)溫度要求是不同的。如早春平均氣溫達(dá)10℃左右,地下30cm土溫在7－10℃時(shí),歐亞和歐美雜交種開始萌芽；山葡萄及其雜種可在土溫5－7℃時(shí)開始萌芽.隨著氣溫增高,萌發(fā)出的新梢便加速生長(zhǎng),較適于新梢生長(zhǎng)和花芽分經(jīng)的溫度是25－38℃。氣溫低于14℃時(shí)不利于開花授粉。漿果成熟期較適宜的溫度是28－32℃，氣溫低于16℃或超過38℃時(shí)對(duì)漿果發(fā)育和成熟不利，品質(zhì)降低。根系開始活動(dòng)的溫度是7－10℃，在25－30℃時(shí)生長(zhǎng)較快。不同熟期品種都要求到有效積溫，如早熟品種莎芭珍珠有效積溫需2100℃，中熟品種葡萄園皇后需2500℃，晚熟品種龍眼需3300℃才能充分成熟。葡萄對(duì)低溫的忍受能力，因各種群和各器官不同而異，如歐亞種和歐美雜種，萌發(fā)時(shí)芽可忍受－3至－4℃的低溫；嫩肖和幼葉在－1℃、花序在0℃時(shí)發(fā)生凍害。在休眠期，歐亞品種成熟新梢的冬芽可忍受―16℃至―17℃，多年生的老蔓在－20℃時(shí)發(fā)生凍害。根系抗寒力較弱，歐亞群的龍眼、玫瑰香、葡萄園皇后等品種的根系在―4℃至―5℃時(shí)發(fā)生輕度凍害，－6℃時(shí)經(jīng)兩天左右被凍死。北方地區(qū)采用東北山葡萄或貝達(dá)葡萄作砧木，可提高根系抗寒力，其根系分可耐－16℃和－11℃的低溫，致死臨界溫度分別為－18℃和－14℃，可減少冬季防寒埋土厚度。（二）光照葡萄是喜光植物，對(duì)光的要求較高，光照時(shí)數(shù)長(zhǎng)短對(duì)葡萄生長(zhǎng)發(fā)育、產(chǎn)量和品質(zhì)有很大影響。光照不足時(shí)，新梢生長(zhǎng)細(xì)弱，葉片薄，葉色淡，果穗小，落花落果多，產(chǎn)量低，品質(zhì)差，冬芽分化不良。所以建園時(shí)，要求選擇光照好的地方，并注意改善架面的風(fēng)、光條件，同時(shí)，正確設(shè)計(jì)行向、行株距和采用合理的整形修剪技術(shù)。（三）水分水在葡萄生命活動(dòng)中有重要作用，營(yíng)養(yǎng)物質(zhì)經(jīng)水溶解后運(yùn)輸?shù)礁鱾�(gè)器官，所以水是營(yíng)養(yǎng)物質(zhì)的載體通過水分蒸騰作用，調(diào)節(jié)樹的體溫并能促進(jìn)水、肥的吸收。如土壤過分干旱，根很難從土壤中吸收水分和養(yǎng)分，光合作用減弱，易出現(xiàn)老葉黃化、脫落，甚至植株凋萎死亡。但水分過多也有害生長(zhǎng)，汛期淹水，一般不超過1周，水滲下后仍能照常生長(zhǎng)；淹水10天以上，會(huì)使根系窒息，同樣可造成葉片黃化、脫落，新梢不充實(shí)，花芽分化不良，甚至植株死亡。葡萄各物候期，對(duì)水分要求不同。在早春萌芽、新梢生長(zhǎng)期、幼果膨大期均要求有充足的水分供應(yīng)，一般隔7－10天灌水1次，使土壤含水量達(dá)70%左右為宜。在漿果成熟期前后土壤含水量達(dá)60%左右較好。但雨量過多要注意及時(shí)排水，以免濕度過大影響漿果質(zhì)量，還易發(fā)生病害。如雨水過少，要每隔10天左右灌1次水，否則久旱逢雨易出現(xiàn)裂果，造成經(jīng)濟(jì)損失。（四）土壤葡萄對(duì)土壤的適應(yīng)性較強(qiáng)，除了沼澤地和重鹽堿示適宜生長(zhǎng)外，其余各類型土壤都能栽培，而以肥沃的沙壤土較為適宜。不同土壤對(duì)葡萄生長(zhǎng)發(fā)充和品質(zhì)有不同的影響。不適宜地區(qū)，可以通過農(nóng)業(yè)工程及栽培技術(shù)進(jìn)行改土栽增。如遼寧盤錦鹽堿地區(qū)，土壤含量0.3%以上，直接栽培葡萄不能成活。但經(jīng)過挖溝臺(tái)田，灌水洗鹽，綠肥改土或局部換土以及選用抗鹽砧木品種等項(xiàng)措施，2－3年后使土壤鹽分降至0.2%以下，就能栽植葡萄。（五）其它在葡萄栽培中，除了要考慮葡萄對(duì)適宜氣候條件的要求外，還必須注意避免和防護(hù)災(zāi)害性的氣候，如久旱、洪澇、嚴(yán)重霜凍，以及大風(fēng)、冰雹等。這些都可能對(duì)葡萄生產(chǎn)造成重大損失。例如：生長(zhǎng)季的大風(fēng)常吹折新梢、刮掉果穗，甚至吹毀葡萄架。夏季的冰雹則常常破壞枝葉、果穗，嚴(yán)重影響葡萄產(chǎn)量和品質(zhì)。因此，在建園地時(shí)要考慮到某項(xiàng)災(zāi)害因素出現(xiàn)頻率和強(qiáng)度，合理選擇園地，確定適宜的行向，營(yíng)造防護(hù)林帶，并有其它相應(yīng)的防護(hù)措施。fghdhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghfjhfhfghfhgfhfhfghdhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghfjhfhfghfhgfhfhfghdhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghfjhfhfghfhgfhfhfghdhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhdghfdhfghhd
