Cultivation and protection technology of rose grapes

The Sunshine Rose grape growing technique is as follows:

1. Land consolidation and planting.

1) Dig a planting ditch (width, depth 1m) in the orchard, and apply 4000kg of rotting sheep manure per mu, mix it evenly with * and backfill it, and irrigate it to settle down, and then ridge (ridge height 20cm, ridge surface width 60cm).

2) If it is trellis cultivation, the spacing of the planting ditch is 1m, and if it is a trellis cultivation, the spacing of the planting ditch is 70-80cm.

3) Before transplanting, the seedlings were treated with carbendazim 1000 times.

2. Fertilization management.

1) Before germination, apply 15kg of fast-acting nitrogen fertilizer per mu to promote germination.

2) At the early flowering stage, 15kg of phosphate fertilizer and potassium fertilizer should be applied per mu to improve the fruit setting rate.

3) During the fruit expansion period, 30kg of potassium sulfate is applied per mu to promote fruit development.

4) In mid-October, 4000kg of rotting sheep manure and 100kg of compound fertilizer are applied per acre to prepare the vines for the next year.

5) Spray potassium dihydrogen phosphate solution every 10 days or so from late April to before fruit ripening and harvesting. In addition to this, before flowering, a borax solution is sprayed once.

3. Water management.

1) When germinating, combine fertilization with a single irrigation.

2) Water about 7 days before flowering, and control water during the flowering period.

3) During the fruit expansion period, irrigation should be carried out in combination with fertilization, and water control should be carried out during the fruit ripening period

4) Before freezing, water is applied once.

4. Other management.

1) If it is a vigorous fruiting branch, keep 2 inflorescences per branch. If it is a fruiting branch with average growth, keep 1 inflorescence per branch. In the case of weakly growing fruiting branches, the inflorescence is not retained.

2) 7-10 days before flowering, thin several longer meristem spikelets at the base of the ear, and cut back the remaining base spikes by 2-3cm.

3) At the beginning of flowering, pinch off the top part of the ear by 1-2cm.

4) Sunshine Rose grape trellis cultivation adopts natural fan-shaped pruning.

5) Winter pruning is carried out about 30 days after the fall of leaves in autumn to about 20 days before germination in the second year, and the principle of winter pruning is that the strong vines are long, the weak vines are short, the upper is long, and the lower part is short.

Choose a garden close to the water source, convenient drainage and irrigation, flat terrain, and sufficient sunlight to build a garden, the garden requires the soil to be rich in organic matter, the pH value is between 6-8, slightly acidic or slightly alkaline, too high and too low will affect the normal growth of grapes, in addition, saline-alkali land is not suitable for gardening, and there are polluted areas nearby are not suitable for gardening. Clean up the early grass and residues in the garden, and then apply 2000 clean organic fertilizer and 100 kg of phosphorus fertilizer per mu in combination with land preparation, do a good job of planting furrows, and build a good grape trellis.

After the grafted seedlings are cultivated, it is recommended to start planting, and it is recommended to choose 15-20 days before the spring grape bud break, and the planting method should also be combined with the local climatic conditions. For example, there is a large difference in spring temperature between the north and the south, so when planting in the north, it is necessary to dig deep planting holes and plant after filling farmhouse fertilizer; In the south, ridge planting after deep ploughing, deep digging of drainage and irrigation ditches, and shallow soil covering after planting.

The above is the Sunshine Rose grape planting technology, I hope to help you if it is convenient, you can please help me like it, thank you.

1. Seedling preparation: Rose-fragrant grapes need to prepare annual winter seedlings before planting. 2. Colonization method:

When planting, lay the root system of the plant flat to ensure that the root system is in close contact with the soil. 3. Apply water and fertilizer: apply fertilizer based on urea or diammonium phosphate during the fruiting period.

4. Management measures: Before the rose-fragrant grapes bloom, it is necessary to take measures such as topping for the plants.

1. Seedling preparation

Rose-scented grapes need to prepare annual winter seedlings when planting, winter seedlings require more than five lateral roots, with three to five full buds, soak in water for 12 to 24 hours before planting, to ensure that the seedling roots absorb enough water, planting time in late November of the current year or early April of the following year.

2. Colonization method:

Dig holes in the soil according to the depth of the roots of the seedlings, lay the root system of the rose-scented grapes during planting, so that the roots are in close contact with the soil, and water them in time after planting.

3. Apply water and fertilizer

Rose grapes have high requirements for water and fertilizer, and sufficient water and fertilizer are required during the fruiting period to meet the growth needs of plants, increase fruit yield, improve high humidity quality, and fertilize fertilizers based on urea or diammonium phosphate.

4. Management measures

Rose grapes before flowering, need to take measures such as topping and pinching the tip of the ear for the plant, pruning the weak branches, over-dense branches, and ensuring sufficient sunlight during the daily maintenance, in addition to paying attention to the prevention and control of pests and diseases, so as not to affect the healthy growth of the plant.

<> giant rose has a strong rose flavor, high yield, disease resistance, and comprehensive traits far exceed the Jufeng and rose varieties, and is the most ideal early generation variety to replace the Jufeng grape. Let's take a look at the viticulture techniques and management methods of the Giant Rose.

The row spacing of the planted plants is meters, and the width of the furrow is 50 centimeters and the depth is 40 centimeters. When planting, 1500 kg of rotting organic fertilizer, 50 kg of calcium, magnesium and phosphorus fertilizer, and an appropriate amount of boron-zinc fertilizer are applied per mu, and the drainage ditch is dug around the orchard to prevent water accumulation.

In the year of planting, select 1 new shoot to be tied upright and upward, and pluck the top when it grows to the meter, and then leave 2 secondary shoots at the top to be tied to the first wire in the opposite horizontal direction, cultivate the main vine, and leave 1 of the secondary shoots germinating on the main vine at an interval of 18 20 cm, so that it forms a T-shaped tree shape.

3 to 5 days before flowering of the fruiting mother branches, leave 5 7 leaves outside the inflorescence for topping, and 15 leaves for vegetative shoots for topping.

As a result, only 1 secondary tip was left at the top of the mother branch, and when the secondary tip was long with 3 4 leaves, only 1 secondary tip was left on the vegetative branch, and 2 3 leaves were left to be topped repeatedly, and the rest of the secondary shoots were all removed, and the ratio of fruiting branches to vegetative branches was 4:1.

You can bag it at the sealing stage, and choose a special bag for white grapes of 23 cm and 32 cm.

Before bagging, select pesticides that have no effect on the production of fruit powder, such as 75% Nadiwin 2000 times liquid + 50% Kaiser 1500 times liquid + 25% amicida 1500 times liquid mixture, spray and dry with mist and finch machine, and complete the bagging operation within 1 2 days.

Giant rose has good yield, mainly with organic fertilizer, nitrogen, phosphorus and potassium combination, medium and trace element supplementation, soil fertilization and root topdressing.

After fruit picking, 1000 1500 kg of rotting organic fertilizer is applied per mu of ditching, adding zinc, boron, magnesium appropriate amount, in mid-May, 15 20 kg of puffed fruit fertilizer (potassium sulfur compound fertilizer, 15-15-15) per mu, 15 days later, 1 more time after 15 days, and 10 15 kg of 50% potassium sulfate fertilizer in mid-June.

It can be combined with spraying pesticides to add zinc, magnesium, iron and other trace elements.

Giant rose has strong disease resistance, and the main diseases are gray mold, powdery mildew and downy mildew under the condition of rain shelter facilities.

When clearing the garden, it is necessary to do a good job of field hygiene; During the pom-pom stage, spray the whole garden with 5 Baumé stone sulfur mixture to reduce the bacterial potential.

During the flowering period, the focus is on the prevention of gray mold and downy mildew; The focus is on the prevention of powdery mildew at the heading sealing stage.

The diseases in the mature stage are mainly gray mold and anthracnose, and the control agents include 20% azoxystrobin 1500 times, 50% Kaiser 2000 times and 37% difenoconazole water dispersible granules 2000 times.

The main insect pests are green blind bugs, Spodoptera litura, aphids, etc., which can be sprayed with 2000 times of 5% wild thorn wettable powder or 1500 times of 5% emamectin benzoate or 2500 times of 70% imidacloprid for control.

1.Choose land to build a garden.

The rose garden has fertile soil, easy drainage and irrigation, high groundwater table, and is planted with neutral alkaline loam, it is best to choose a place with a gentle, flat slope. Before planting, dig deep into the soil and remove debris. Planting furrows are generally dug straight with a depth and width of 80-100 cm.

After digging the planting ditch, fill the 20 cm thick straw crop, mix the straw with the topsoil and fill it up, apply 3000-5000 kg of cooked farm fertilizer per mu, and mix the topsoil and straw to fill the bottom of the ditch. After backfilling, repair the ridges on both sides of the ditch, add water, compact, fine rake, and prepare for sowing.

2. Transplantation. When transplanting, seedlings that grow for 1 year, cm or more, more than 5 lateral roots, and 3-5 flower buds should be selected. Soak the seedlings in water 1-2 days before transplanting, and transplant them after the roots absorb enough water.

Rose grapes are usually planted at the end of November or early April, and in the case of nutrient bowl seedlings are best planted in April and May.

Each year, the seedlings are dug in the planting furrow and then planted according to the depth of the seedlings in the nursery. The large-area nutrient bowl seedling planting can be made with a hole punching machine, the seedlings are filled into the hole with soil, and the surrounding soil can be watered according to the truth, and the area is small and the annual seedlings can be raised.

3. Plastic decoration.

In the first year, when the new shoots have grown to meters, the core can be plucked out to make them grow boldly. Generally, leave 1 secondary tip at the top, leave 3-5 leaves and repeat the core pulling, and leave 1-2 leaves to repeatedly pull the core.

In the second year, after germination and plucking of bamboo shoots, the tendrils of the main branch pick out a small and strong branch as an extension tip, and the other new shoots are left weak and strong, dense and thin, and the main branch is stretched and the long branch grows in cm and is repeatedly topped.

In the third year, the main tendrils grow a strong new shoot every 30 cm from more than 60 cm above the ground, which remains as the mother branch of the fruit.

4.Management of soil, fertilizer and water.

Shelf in the spring, according to the old, in early spring when the temperature is very low, in order to increase the number of bales and cover the ground, in July this year, weeding is generally in May - September, deep and unsuitable and fruits, 8 - 10 cm is appropriate, must be carried out 4 to 8 times a year, can break the hardening of the soil, promote the growth and development of the root system.

Fertilization should be mainly fertilization, supplemented by top dressing; Farm fertilizer is the main fertilizer, supplemented by chemical fertilizer, fertilizer should be determined according to soil fertility and forest size, more application of thin land, less fertilizer; There are many large trees and few small trees.

When planting annual young trees, it is necessary to combine top dressing with timely watering, and the watering of fruiting trees should be flexibly grasped according to the growth needs and water. Generally, the grape buds are watered once before watering, 10 days before flowering, top dressing and watering are set up half a month after flowering, and the combined basal fertilizer is applied once after fruit picking, and cold irrigation is carried out before watering in winter.
