The common cultivation method of rose fragrant grapes is

Answer 1

The common cultivation methods of the rose fragrant grapes were as follows:

* * 1. Planting Techniques **
1. * * Seedlings selection **: Choose an annual seedling with a stem diameter of at least 0.4 cm, more than 5 lateral roots, and 3 - 5 full buds on the side branches.
2. * * Seedlings Treatment **: Soak the roots of the selected seedlings in clear water for 12 - 24 hours. It can be soaked 1 - 2 days before planting. After the roots are full of water, they can be planted.
3. * * Land selection and preparation **
- Soil requirements: Choose a place with fertile soil, convenient drainage and irrigation, moderate underground water level, and neutral or slightly basic loam soil. The soil should have a ph of less than 8, be resistant to salt and alkali-tolerant, and be suitable for land with gentle slope and flat terrain. Before planting, dig deep into the soil, remove debris, and dig planting ditches with a depth of 80 - 100 cm. The ditches were filled with a mixture of 20 cm thick straw crop debris and topsoil, and 3000 - 5000 kg of decomposed farmyard fertilizer was applied per mu. After the filling, the ridge was filled with water, compressed, and raked to prepare for sowing.
4. * * Planting **
- When planting, dig a ditch hole and plant the seedlings with the original soil. The roots should be spread out in the soil and all the roots should be buried. After planting, press the surrounding soil and water them in time.
- The transplanting time was generally at the end of November or the beginning of April of the following year, and the nutrition bowl seedling was suitable for April to May. According to the depth of the seedlings, they could dig holes and plant them.

* * 2. Management Techniques **
1. * * Water and fertilizer management **
- Before sprouting, 30 - 40 kg of dibasic amine and 15 - 20 kg of carboric acid could be applied per mu.
- Before flowering, apply 20 - 30 kg of diammonium orthonate, and spray 0.3 - 0.5% solution of tribution at the early flowering stage.
- After the berries are colored, spray 0.2 - 0.3% of the solution of monobium hydrogen orthonate once every 7 days for 3 - 4 times. Water the soil properly every time you apply fertilizer, and keep the soil slightly moist.
2. * * Trimmed and wiped **
- The growth state of the plant is stable. After the new leaves of the branches are sprouted, they can be trimmed appropriately. In the year of fruit bearing, the heart should be picked in time and repeatedly. The secondary shoots should be cut off and the ears of flowers should be repaired. It is enough to leave 1 - 2 ears on each bearing branch.
- The secondary shoots under the ear were all wiped off from the base, and the secondary shoots above the ear were pinched in time after leaving 1 - 2 leaves.
- In the first year, when the new shoots grew to 1 - 1.5 meters, the core was removed to promote growth. Leave a secondary shoot at the top, leave 3 - 5 leaves and remove the core repeatedly. In the second year, after sprouting, the bamboo shoots were removed, and the small and strong branches were selected as extension shoots, while the other new shoots were left weak and strong, sparse and dense. When the main branch extended to 1.5 - 2 meters long, the heart was repeatedly pinched. In the third year, a strong new sprout was selected from every 30 centimeters above 60 centimeters from the ground as a fruit branch.
3. * * Whole panicle covered **
- Remove 1/5 - 1/4 of the tip of the ear, remove all the worms and deformed particles, and use a paper bag with good ventilation. You can spray a disinfectant such as carbendazim on the ear, and then cover the bag. Remove the paper bag 10 days before harvesting.
4. * * Harvest at the right time **
- It was best to harvest the fruits in the cooler hours such as the morning or evening. During the harvesting process, it was to avoid man-made damage to the fruits and to cut off the sick and insect grains.
5. * * Clean the garden to prevent cold **
- Clean up the orchard thoroughly. Cut off all the insect branches and old branches. Clean up the weeds, fallen leaves, and fallen fruits. You can choose to bury them deep in the distance or burn them all. From mid-November to early winter, the branches and vines were removed from the shelves, tied up, and buried to prevent cold.
