Sapphire grapes due to the blue and black sapphire fruit is about 5 cm long, it resembles a small cylinder. For this reason, it is also known as the "Tears of The Moonlight". After the fruit is cut, there is no extra juice, it is very sweet and delicious. Therefore, it is particularly popular and loved in fruit varieties.
Sapphire viticulture techniques:
Moisture management requirements: Sweet sapphire grapes have several periods to pay attention to when growing and cultivating:
First, before germination, this is the first critical period, one of the critical periods of its needs.
The second is that 10 days before its flowering is the second critical period, and during this period, we should pay attention to sprinkling water.
The third is about 10 days after the fall of flowers, which is the third critical period, but also the period of fertilizer and water, when the beginning of the coloring of sweet sapphire grape berries is the second peak period of berry growth, at this time we must pay attention to the supply of suitable fertilizer water.
Soil requirements: Sapphire grapes are still relatively adaptable to soil, especially suitable for sandy loam soils rich in organic matter and fat.
Generally speaking, the thickness of the soil layer of the vineyard is generally more than 80-100cm. The more suitable groundwater level should be below 1.5-2 meters, generally in the slightly acidic environment with a PH of 6-6.5, the growth results of grapes are better.
Fertilizer nutrient requirements: Sapphire grape nutrient requirements have in common with other fruit trees, nitrogen, phosphorus, potassium, calcium, magnesium, boron, etc., but also have their own characteristics, each 1000KG grapes, need to absorb 3-6.6 kg (kg) nitrogen, 1-3kg phosphorus, 3-6.5kg potassium from the soil, the demand for potassium is at least as much as nitrogen, and even more than a certain amount.
"Nitrogen and phosphorus" are mainly based on the absorption of organic states. This supply of fertilizer ensures that the grape variety is sweet and not sour, and also controls the growth of the grape branches and leaves.
The growth cycle of sapphire grapes is relatively short, and the harvest period from the growing period only takes 4 months, while the more ordinary varieties save almost two months of time, and they are basically ripe at the end of August!
Sapphire grapes are delicious and well fed, simple and easy to use, planting skills are all here, hurry up and collect
Although the sapphire grape looks very noble and seems to be very difficult to raise, in fact it is very good to maintain, as long as you master the corresponding skills, it can grow well and produce a lot of fruit.
Sapphire grapes are very promising varieties, because for a new variety can not have good prospects for development, generally to meet the conditions of large grains, high sugar, good planting, good fruit shape, and sapphire grapes are just satisfied.
