大棚条件下对弗雷无核葡萄生长及果实品质的影响

Effects of Greenhouse Cultivation on the Grown and Fruit Quality of Flame Seedless Grapes

葡萄大棚栽培前期促成、后期避雨(简称促成-避雨栽培)模式是新近发展起来的一种保护性栽培模式。试验通过对弗蕾无核枝条生长量、物候期、果实品质及病虫害防治等的调查,进行对比分析。结果表明:大棚栽植可以有效的规避晚霜的伤害,提早萌芽,新稍生长量显著高于露地栽培,物候期比露地栽培的早7d左右。且病虫害发生显著低于露地栽培,防病次数少于露地栽培,药品也多用于预防病害发生,浓度较低。大棚栽培的葡萄果面干净、果实鲜红靓丽,单粒重、单穗重均比露地栽培的高,可溶性糖高于露地栽培。因此大棚栽培的弗雷无核葡萄果实品质和商品性都好于露地栽培。

Greenhouse grape cultivation can contribute to mature in the early and take shelter from rain in the late,the mode is a newly developed a kind of protective cultivation mode. The data about Flame seedless branches growth, phenologieal period, fruit quality,disease and insect prevention and control were comparatived and analyzed. The results showed that greenhouse cultivation can effectively avoid late frost damage, early germination,new growth slightly higher than open field cultivation, phenology than outdoor cultivation as early as about 7 d. The occurrence of plant diseases and insect pests was significantly lower than that in open field. The frequency of disease prevention was less than that in open field cultivation,and the drugs were also used to prevent the occurrence of diseases, and the concentration was low. In greenhouse, grape fruits were clean and bright and beautiful. Single grain weight and single panicle weight were higher than those in open field, and soluble sugar was higher than that in open field. So Flame seedless grape fruit quality and commodity by the greenhouse cultivation were the better than that of open ground.
