最近有很多热心网友都十分关心冬季的葡萄是反季节的吗,请问反季节葡萄是如何种出来的?这个问题。还有一部分人想了解冬季的葡萄是反季节的吗。对此,绿润百科小编「初心不变i」收集了相关的教程,希望能给你带来帮助。
反季节葡萄是通过一种叫“花芽分期”的技术实现的。主要理由如下:
1、反季节葡萄种植要控制好温度。种植过程分为早、中、晚期,葡萄种植需要在11月底种完,12月开始增温,达到积温后葡萄长得快,20多号开始发芽。前期白天温度要达到二十七八摄氏度,晚上需要保持在十七八九摄氏度。到了中后期温度就要缩短至二十二摄氏度左右;
2、反季节葡萄种植要控制好光照。种植大棚玻璃上要有日光纹,它可以增强光照,隔离紫外线,这有利于加快葡萄的授粉过程,缩短其生长期;
3、反季节葡萄种植要控制好水分。到了中后期,要少浇水,拉开白天与晚上的温差有利于葡萄生长。早期则要多浇水。并且先用氮肥,后用钾肥。铁、锌、钙、镁、钼等9种微量元素也是葡萄生长所必须的。
问:冬季的葡萄是反季节的吗?
答:是的,冬季的葡萄属于反季节水果。
那么,什么是反季节水果呢?
反季节水果是指在其正常成熟期外采摘或处理的水果,这种水果的供应期要比它们正常成熟期出现的早或晚。
为什么会有反季节水果出现?
现代科技的进步,使得人们可以进行人工控制种植环境,逆境生长,以及通过提前摘取、储藏和生长等方式调整水果成熟周期,使得这些水果在不同的季节里生长,实现了供应期的延长。
但是,冬季的葡萄虽然被称为反季节水果,但是也并非完全违反其自然生长规律,因为人们通过北半球地区温室、光照、水分等条件的控制,使得葡萄的生长环境接近其在南半球地区正常生长的时期,因而能够保持葡萄的原有品质和口感。
【英文介绍/For English】:
Off-season grapes are achieved through a technique called "flower bud staging". The main reasons are as follows:
1. The temperature should be well controlled in off-season grape planting. The planting process is divided into early, middle, and late stages. The grapes need to be planted at the end of November, and the temperature will start to increase in December. After reaching the accumulated temperature, the grapes will grow quickly, and the 20th will begin to germinate. In the early days, the temperature should reach 278 degrees Celsius, and it needs to be kept at 1789 degrees Celsius at night. In the middle and late stages, the temperature will be shortened to about 22 degrees Celsius;
2. For off-season grape planting, the light should be well controlled. There should be sunlight patterns on the glass of the greenhouse, which can enhance the light and isolate ultraviolet rays, which is conducive to speeding up the pollination process of grapes and shortening their growth period;
3. Water should be well controlled in off-season grape planting. In the middle and late stages, less watering is required, and the temperature difference between day and night is conducive to the growth of grapes. In the early days, water more. And use nitrogen fertilizer first, then potassium fertilizer. Nine trace elements such as iron, zinc, calcium, magnesium and molybdenum are also necessary for the growth of grapes.
