巨峰葡萄简介

巨峰葡萄,属中熟类、四倍体品种,欧美杂交种,原产日本。大井上康于1937年用大粒康拜尔早生为母本,森田尼为父本杂交培育。1959年引入中国,并在全国各地大面积推广,成为深受果农欢迎的主栽品种。

巨峰葡萄败花严重,坐果率低,果穗松散,重摘心可以提高巨峰葡萄坐果率,增加产量,改善品质。葡萄开花前7-10天,结果枝在花穗以上保留2-3张叶片、营养枝保留5-6张叶片摘心,主蔓延长枝到立秋前后摘心。结果枝和营养枝除保留先端1个副梢外,其余副梢全部抹除。结果枝和营养枝先端的副梢长到一定长度时分别保留6-8张叶片和8-10张叶片摘心,其上发生的两次副梢和主蔓延长枝的副梢均保留1张叶片反复摘心。

在摘心和处理副梢的同时,根据负载量疏去多余果枝、营养枝和果穗,留下的果穗去掉穗尖的1/4至1/5,并去掉副穗。

巨峰葡萄,果实成熟时果穗上的果粒应着生一致,粒重10-14克,紫黑色,果粉多,汁多有肉囊,味甜酸,有草莓香味。无核率达95%以上,糖度17度以上,果穗自然、完整、紧凑,无病斑、无病果、果粒大小均匀、外观着色度基本一致,果实新鲜清洁、无异味、口感好。大、粒大、单粒重10克左右。巨峰葡萄生长需水特性,在湿度管理上有不同的要求:芽萌动期到花前,相对湿度控制在70%~80%为宜;花期要求相对干燥,利于花药开放和花粉散发,过于干旱又易出现花冠不开裂脱落干枯在花蕊上不正常现象,影响坐果。

常吃巨峰葡萄的好处和坏处

常吃葡萄好处多多,葡萄的营养价值很高,各种维生素、氨基酸、蛋白质、碳水化合物、粗纤维、钙、磷、铁、胡萝卜素、硫胺素、核黄素、尼克酸、抗坏血酸、卵磷脂等,特别是现代医学发现,葡萄皮和葡萄籽中含有一种抗氧化物质白藜芦醇,对心脑血管病有积极的预防和治疗作用。中国古代医学对葡萄药用也有记载。葡萄性味甘,酸,平,入肺,脾,肾经,能补益气血强筋骨、通经络、通淋消肿、利小便、滋肾益肝。

医疗上能起到补肾、壮腰、滋神益血、降压、开胃的作用。科学吃葡萄吃葡萄时,我们一般都把葡萄皮吐掉,殊不知,葡萄皮是一种良药。科学研究发现,葡萄皮中含有一种叫白藜芦醇的化学物质,可以防止正常细胞癌变,并对小鼠皮肤癌具有防治作用,说明这种物质具有良好的防癌、抗癌作用。建议一定不要贪吃,否则坏处就随着到来,会影响食欲,不好好吃饭,造成某些微量元素过多,其次糖类含量过高会对身体各方面造成影响,如龋齿、酸中毒等等。

种植巨峰葡萄对温度的要求

保护地果树栽培的成败,温度的调控是关键。因此,扣膜初期的3~5天是全盖帘期,待地面完全解冻后,葡萄经过自然预备、短暂适应后,开始白天揭帘升温。升温按生长阶段的不同,大致分为三个阶段管理。前期,萌芽到开花前,由于棚内白天温度可迅速提高到23~25℃。采光好、保温佳的温室可提高到27~28℃。要注意,超过25℃时应及时小放顶风,控制温度。

前期温度过高,往往生长发育不整齐。放风的同时,能补充CO2。此时夜间应注意保温,使温度维持在7~8℃。中期,开花前后,由于开花授粉对光照的要求极为敏感,白天要尽量增加日照,升温,同时及时换气。温度控制范围是25~28℃为宜。超过30℃,应注意开放顶风,换气降温。夜间做好保温,使温度维持在14℃以上,以利于授粉受精,提高坐果率。

后期,浆果膨大至成熟,自然温度开始回升,棚内外温差小,容易控制棚内温度,可维持棚内白天28~32℃,夜间15~17℃。昼夜温差控制在10℃以上,利于浆果上色。

巨峰葡萄是碱性水果还是酸性水果?

葡萄是碱性水果。酸性食品和碱性食品的划分不是根据口感,而是根据食物在人体内最终的代谢产物来划分的。

如果代谢产物内含钙,镁,钾,钠等阳离子,即为碱性食物;反之,硫,磷较多的即为酸性食物,所以醋和苹果味道虽酸却是碱性食物.碱性食物有瓜果,蔬菜,豆制品,乳制品,海带等;常吃的鸡,鸭,鱼肉,蛋,米,面,油糖,酒都属于酸性食物。

葡萄科葡萄属木质藤本植物,小枝圆柱形,有纵棱纹,无毛或被稀疏柔毛,叶卵圆形,圆锥花序密集或疏散,多花,与叶对生,基部分枝发达,果实球形或椭圆形,种子倒卵椭圆形,花期4-5月,果期8-9月。

如上所述,巨峰葡萄虽然营养价格丰富,但也不能经常大量使用,过多食用会食欲下降,糖分过多对身体有一定的影响,所以要适合而止哦!小孩吃的话记得吃完漱口小心长蛀牙。
