Rose-scented grape planting technology

Rose grape is a kind of fruit variety with a long history, which can be seen in most parts of our country. Generally mature before and after the annual Mid-Autumn Festival, the ripe fruit is dark purple or black, sweet with a little sour taste, eaten in summer, especially Shengjin appetizer.

Planting techniques of Rose-fragrant Grape

1. Seedling preparation. One-year-old winter seedlings with thickness above 0.4cm, lateral roots more than 5, stem diameter more than 0.6cm, with 3 ~ 5 full buds, soaked in 1d~2d for 12 ~ 24 hours before planting, made the seedling roots absorb enough water, and the green leaf seedlings cultivated in the same year required the seedlings to be above 15cm and three leaves with one heart.

2. Planting period. In the cultivation of rose grape, it is suitable for winter storage seedlings in late November or early April of the following year, and nutrition bowl seedlings from late April to early May.

3. Planting method:

Annual winter storage seedlings. Dig holes in the planting ditch according to the depth of the seedlings in the nursery. When planting, make the root system extend around and connect closely with the soil, and water it in time after planting.

Nutrition bowl, green leaf seedlings. When planting in a large area, a self-made punch can be used to make a circular cylinder with upper 6.5cm, lower 5.5cm and high 20cm, which is made of thin iron plate, and the upper handle is welded bottom down to take soil and drill holes. Take off the nutrition bowl, put the seedlings with soil into the hole, fill the soil around and water it. Planting in small areas is the same as storing seedlings in winter.

In the cultivation of rose grape, it is appropriate to plant deep and shallow soil in arid areas with difficult water sources, cultivate soil year by year, increase root quantity and improve drought resistance.

Fertilization method of Rose fragrant Grape

1. Sprouting and fertilizing. In the first and middle of April, before sprouting, fully mature organic fertilizer was applied, 15-20 kg of urea and 30-40 kg of diammonium phosphate per 667m2. If the base fertilizer is sufficient, this fertilization can be avoided.

2. Fertilize the flowers. About 10 days before flowering, 15-20 kg urea or 20-30 kg diammonium phosphate was applied per 667m2. 0.3% boric acid or borax solution was sprayed once at the early flowering stage and at the full flowering stage.

3.Fruit fertilizer. During the expansion period of grape berries, fully mature organic fertilizer or urea 15 kg and diammonium phosphate 30-40 kg were applied.

4. accelerate ripening and fattening. The grape berries were sprayed with foliar fertilizer before and after coloring, and 0.2-0.3% potassium dihydrogen phosphate solution was sprayed outside the roots, once every 7 days or so, for a total of 4 times, or a multi-component compound fertilizer containing phosphorus, potassium and calcium. 0.5% calcium amino acid or calcium acetate is sprayed for storage to facilitate fresh storage.

Tips on pruning Rose-fragrant Grape

The grape mainly grasps the principle of "one look, two thinning, three cuts and four checks" in the pruning steps.

1. "look" is the premise and a pruning survey. First, look at the climate, soil, variety, tree shape and tree potential, and then look at the relationship with neighboring plants to determine the plant load, pruning plan and the number of pruning eyes.

2. "sparse" is to remove disease and insect branches, thin and weak branches, withered branches, over-dense branches, local renewal of weak main and side vines, remove useless rhizosphere sprouting branches, and cut out the outline.

3. "cutting" is processing, that is, according to the habits of the variety, determine the cutting length of each branch according to different conditions, including tree age, frame type, tree shape, growth, different parts and different branch quality.

4. "check" is the end, that is, check again after the pruning to see if it is missing, and check for errors to make up for it.

Water and Fertilizer Management of Rose fragrant Grape

1. Water the sprouts thoroughly and water them 7 to 10 days before sprouting.

2. Water thoroughly before flowering, 7 to 10 days before flowering, and no watering for 10 to 15 days.

3. Water should be watered thoroughly during the fruit expansion period, once every 10 to 15 days.

4. Water should be controlled during the coloring period, mainly small water, which is easy to crack fruit with large water.

5. Water should be thoroughly watered during the winter irrigation period, and watered before freezing after falling leaves.

6. fertilization is mainly concentrated fertilization after harvest, while topdressing four key fertilizers for a total of five times.

The most important thing in the cultivation of rose grape is that the fertilizer and water technology should be done well, and the later management is also very important. Only by doing a good job of these tasks can we ensure that the quality of the grapes will be excellent in the later stage, otherwise there will be grain loss and uneven grape size.
