When white rot, downy mildew and ear axis brown blight of low temperature and rainy grape occurred in 2005, Royer rose, seedless cold honey, jasmine and honey grape still had a bumper harvest. two。 The taste is good and the commodity price is high: Royer roses can be sold at 3 yuan per jin in the nine Taiwan market because of their rose red, strong rose fragrance and moderate sweetness and sour; seedless honey is seedless and can be eaten with skin because the skin is crisp and soft, and the market price is 4 yuan per jin; jasmine can be sold at 5 yuan per jin because of its strong jasmine fragrance Although honey is an old variety, because it is a red and large-grained variety, it is moderately sweet and sour, and the price is 3 yuan per jin. As these varieties are rare in the market, they are in short supply and have a bright future. 3. There is no phenomenon of big and small years when the branches mature well: if the grapes of general varieties leave too much fruit in normal years, the fruit branches are not mature (green) in autumn, and the buds do not sprout in the coming year, resulting in blindness. Even when the fruit is kept normally, the fruit branches can only mature more than half. Royer roses, no matter how many ears are left, the branches mature to the top: seedless honey, jasmine and honey ripens better under normal fruit. The above varieties do not appear the phenomenon of big or small years because the branches are mature well. 4. Very hardy: the lowest temperature in winter in Changchun can reach about 34 ℃ below zero. Generally, grape varieties grafted with hardy rootstock Beida have to bury the soil in winter with a thickness of not less than 20 cm on the vines. And the above grape varieties, cold-proof soil buried 10 cm thick can safely survive the winter, which is inferior to the general varieties. 5. The seedling rate of grafting is high: grape varieties can be grafted with Beida as rootstock, but the affinity is different. For those varieties with weak affinity, they appear to have healed, but the seedlings grow weakly after planting, and as a result, they die due to weak resistance. As long as the above grape varieties are correct grafting techniques without peeling seedlings, the seedling rate is very high.
