1, excellent quality. The rich rose fragrance is mixed with osmanthus fragrance, the flesh is crisp and juicy, the skin is thin and not astringent, and the sugar degree is generally 22, and the highest is 28 degrees.
2. Disease resistance. The comprehensive disease resistance was higher than that of Xiahei and Jufeng.
3. The flower buds are well differentiated and can be pruned with short tips.
It is developing vigorously. The newly-built garden can be quickly formed and has high bearing capacity. The yield per mu is more than 4000 Jin, and the sugar content can reach more than 23 degrees.
5, it is easy to be seedless, and the flavor is better after seedless.
6. The fruit granules are large, and after puffing treatment, the fruit granules of more than16g can be obtained, and the flavor is not affected.
7. The branches are lignified.
8, the fruit is resistant to storage and transportation. When the ear shape is not good, cut and package the fruit with stem, which can be transported for a long distance and stored in cold storage.
Second, the shortcomings of sunshine rose grape seedlings
1, the size and size of granules are heavier, especially in the case of improper hormone treatment.
2. The symptoms of virus disease are common, especially the grafted seedlings of Peking University rootstock, and the seriously diseased plants cannot form yield.
3, easy to produce fruit rust, where the fruit color reaches golden yellow, almost all produce fruit rust, under normal circumstances, consumers will not care too much.
4. It is prone to sunburn. When planting, short branches near the ear must leave 1 ~ 2 leaves to cover the ear and increase the density of branches.
Third, the cultivation and management of sunshine rose grape seedlings
Sunshine roses grow vigorously and are suitable for grafting with relatively strong rootstocks. In the process of cultivation, it is necessary to provide sufficient growth space for sunshine roses.
Cultivation frame: Sunshine rose should be planted sparsely, and large H frame (horizontal flat shed frame and V-shaped horizontal frame) and straight frame (wide V frame and flying bird frame) should be adopted to provide enough growth space for root extension and branch growth of Sunshine rose.
The 3-year-old Sunshine Rose Vineyard in Changzhou, Jiangsu Province has a linear structure and long branches every year. The skeleton of this tree is very big, which is beneficial to the growth of the tree.
Pruning: Sunlight rose trees form quickly. After one year's cultivation, the stems can be 2-3 cm long and thick.
In winter pruning, two buds are used for short pruning, and a word frame can be updated by combining long and short pruning. The flower buds are well differentiated.
Some growers report that the flower buds of Sunshine Rose are not well differentiated. In fact, the flower bud differentiation of sunshine rose is better, which is related to cultivation management. Generally speaking, excessive temperature in greenhouse and unreasonable use of fertilizer affect flower bud differentiation, and serious downy mildew planting in the open air leads to insufficient nutrient accumulation and poor flower bud differentiation.
Prune in summer, keep good fruiting branches, with an average of 20 cm per ear, take 6 leaves for coring, and leave 1-2 leaves for secondary shoots to be picked repeatedly. If it is extended a little, it will not be coring. Sunshine roses are easy to get sunburned, so it is recommended to leave two leaves near each ear and pick them before and after the discoloration period.
Four, the prevention and control of diseases and insect pests of sunshine rose grape seedlings
Sunshine rose is not well cultivated in the open air, and various diseases are serious. In addition, the anti-fruit-hanging advantage of sunshine rose (it can be sold step by step and get better income) cannot be realized by open-air cultivation. It is suggested that sunlight rose should be cultivated in greenhouse or shelter from rain.
Prevention and treatment of green blind stinkbug: The harm of green blind stinkbug is widespread in vineyards in southern China. Insect pests occur early, often at the stage of grape pilling and when the buds turn green. It develops rapidly, and the juice on the ear can be sucked dry in a day or two. Because pests can be transferred, it is suggested that adjacent orchards cooperate to control them.
Prevention and control of downy mildew, gray mold and anthracnose: Downy mildew and gray mold are easy to be infected before and after the sunshine rose period, so we should do a good job of prevention at ordinary times, and remember that bagging is also necessary for shelter from rain and greenhouse cultivation.
Diagnosis and control of grape diseases and insect pests can normally prevent downy mildew, anthracnose, gray mold and white rot.
