1、防凍:在葡萄樹四周鋪蓋一層稻草,進行保溫,避免植株被低溫凍傷。2、澆水:入冬前澆一次封凍水,不用勤澆水,避免土壤積水,影響植株正常生長發(fā)育。3、施肥:定期施薄肥,保持土中有充足的養(yǎng)分,增加植株的耐寒性。

  葡萄適宜栽植在通風(fēng)、向陽、排水良好的肥沃地塊。我國北方多采用春季栽植,一般在4月中下旬即可進行田間定植。

  葡萄對水分要求較高,嚴(yán)格控制土壤中水分是種好葡萄的一個前提。葡萄在生長初期或營養(yǎng)生長期時需水量較多,生長后期或結(jié)果期,根部較為衰弱需水較少,要避免傷根免影響品質(zhì)。

  葡萄忌雨水及露水,雨多年份易造成日照不足,光合作用受限制,過多吸收水量易引起枝條徒長及濕度過高。缺水及易干旱地區(qū)要適當(dāng)墊蓋稻草,用以保持土壤濕度,同時也可控制草的生長。
