Sapphire grape is a high-quality grape, the fruit of sapphire grape is blue-purple, the fruit is relatively long, pointed, sweet to eat, rich in juice, and currently highly evaluated by consumers. Sapphire grape seedlings are a variety that was launched only a few years ago, is an excellent variety of grapes, and is currently planted in large quantities, so, sapphire grapes**, nutritional value, taste, how to plant sapphire grape seedlings? Let's take a look!
First, the prospect of sapphire grape industry
When it comes to the future of the sweet sapphire industry, it is first necessary to understand its supply and demand, as well as the characteristics of fresh fruit. Only then can we draw the corresponding conclusions.
1. Supply and demand
According to the statistics of the past few years, the price of domestic imported sapphires to Hong Kong is only a dozen yuan per catty. However, scarcity is expensive, and at present, our domestic sapphire has just begun to be planted, and the amount is not large. Therefore, in the autumn and winter, when the sweet sapphire of Yunnan Jianshui is listed for the second time, the purchase price of the land can reach more than 25 yuan per catty. In this respect, the price of sweet sapphire is relatively high for a limited period of time in the future, coupled with the relatively simple management, low production cost and high yield, so it is likely to become one of the highest vineyard varieties in existence.
2. Fruit characteristics
According to the Chinese Red Grape Winter Fruit Review Conference held in Jianshui, Yunnan Province last fall, the color of sweet sapphire is very good, but according to tests, it has a sugar content of only about 11 degrees. In other words, it's a typical first color, then added sugar.
In addition, although the sweet sapphire fruit has a unique shape and novel appearance, which makes people want to grab the freshness after looking at it, it has no fragrance, which has become one of its biggest drawbacks. For this type of wine, if the red grower prefers to grow other wine varieties and simply pursues perfect yields without paying attention to quality, it is likely that sweet sapphire will be very risky in the near future.
3. Conclusion
Therefore, for sweet sapphire, fruit friends must remember the following three points, one is to take the lead, because it is the supply and demand relationship that determines the best thing. The second is to rest assured, because at present, we have too many experts who are actively summarizing the production technology of sapphire. The third is to avoid greed, not to blindly expand production because of the high price of sapphire, and not to ignore the quality because it is easy to color. Otherwise, consumers will not form repeat purchases, then our fruits are destined to be unsalable.
In addition, for the growers who have planted sweet sapphires, it is necessary to master the planting technology as soon as possible, take advantage of the highest advantages at this stage, and make quick profits. For those who are still hesitating, we should emphasize that according to the tracking survey of the past two years, most of the Xi and production characteristics of sapphire are almost summarized by many authoritative experts in red planting, and we have technical references to plant with confidence. However, with the passage of time, when sweet sapphire is planted, the large area is to a certain extent, and its cultivation profit is difficult to guarantee.
2. Sapphire grape flavor and nutrients
The sapphire grape fruit is cylindrical, shaped like a little finger, 5 fingers long and blue-black, with a grain weight of about 10 grams. The taste is authentic, sweet and crunchy with little residue. It has more than 10 times more nutrients than regular red grapes and is very sweet. Sapphire grapes are more suitable for cultivation in Shandong.
Third, the cultivation of sapphire grapes
Sapphire grape peach is poorly hardy. Autumn is easy to die of cold. It is best to plant in the spring. In general, both open-field cultivation and greenhouses are planted in the spring. Due to the weak upward trend of plants, greenhouse cultivation must control humidity and temperature for better growth and development. Before planting sapphire grape seedlings, solve the problem of soil subsoiling. After the soil thaws, the seedling problem begins. Prune excess branches and plant grape seedlings at regular intervals. Greenhouses can also be used to plant trees before the shed is built. Sapphire grape seedlings every 7 times after planting; Water every 10 days and resume conservation when fully viable. Generally, the soil is watered after drought, and fertilized 3 times during the growing season. In July, you can gradually reduce the amount of watering and spray strong fruit fertilizer to the bottom of the leaves every 15 days.
