Sunshine rose grapes are now a very hot plant, with very good fruit quality, strong rose scent and high fruit sugar, which is popular with consumers. However, solar rose grapes are generally grown in the rain sheds, especially in the southern regions, which are prone to decomposition and have a significant impact on quality and yield due to heavy rainfall, high temperatures and humidity, and the absence of rain shed cultivation. The main diseases of grapes, such as grey disease, albinism, acidosis, black pox, etc., are also well controlled by rain-shield cultivation, which has been widely promoted in the country's hot and rain-fed areas。
1. Determination of line spacing
Sunshine roses require a leaf fruit ratio of at least 16:1, so they require a higher range, a simple shelter flyer, with a recommended range of 2. 8 to 3 m; for long distances, trees are too strong or too weak to contribute to the production of high-quality sunshine rose grapes, so that the length of the plant is adjusted to the species of gillwood and soil conditions. 3-4 m range is used if the sun roses that are grown up to be 5bb, 3009m and so4 are in good condition, and 2-3 m range is used if the logs are in summer black or beida, or if the soil and the water are in poor condition (figure 1)
Figure 1 determination of line spacing
In order to ensure the production of the sun rose vineyards, the primary shear period, and the use of 1. 5 metres for many new seedlings, we have to separate them from each other in the third year of planting, and eventually reach the standard distance of 3 metres。
2. Choice of configuration
The vast majority of vineyards built before 2015 are double-crossed “v” shelves, with a backbone height of not more than 0. 8 metres and a shed height of not more than 2. 2 metres, usually with a range of 2. 3 to 2. 5 metres, or so-called low-dry “v” shelves. After many years of practice, this type of frame is not suitable for the production of high-quality sun rose grapes, and it is used to grow sun rose grapes in such a way that they are nourished by hyperplastic growth, ill-photernized branches, suboptimal lumbering of flowers, heavy grains of fruit size, light smell of fruit and low sweetness. According to the growth patterns of sun roses and the practice of many years at home and abroad, high-yielding sun roses are best achieved by using a high-crystal type — the “flying bird shelf” (figure 2) — which transforms the growth state of the result branches from a straight-slash growth to a tilted growth and a downsliding at the front end of the medium term, in order to inhibit excessive nutritional growth and promote flowering and fruit growth。
Figure 2 flying birds
Flying birds are the first of its kind to be created by wu jiang researcher at the zhejiang agricultural institute. The flyer not only overcomes the pittings: the head of the heart, the fruit, the raising of the hand, or the risk of falling on the stool, but also solves the risk of the double-crossing “v” frame bending, crouching down, with strong upper edges, a high number of heart breaks, high labour intensity, low efficiency, insecurity, etc., thereby increasing labour efficiency, as well as reducing tree positions, increasing the rate of seating, improving the colour and quality, and being suitable for mechanized field operations, such as lacquering and cutting, stripping or circumcising。
3. Design of the shelter
The construction of a shelter can effectively reduce the incidence of disease, reduce the number of medicines used and facilitate the production of healthy and high-quality fruit. The main parameters for the construction of the shed are as follows:
3. 1 cement poles planted
The sunshine rose vineyard, which we recommend, is about 3. 2 metres long with a concrete pole at a distance of 7 metres, which is buried 50 centimetres beneath the ground, with a 50 centimetre null zone. A beam is set at 2. 2 m, with a steel pipe (or triangle) and a beam of 1. 5 m long, permeating each side at a mid-point of the beam at a point of 35 cm each, with a total of four holes and a total of four wires. Then a wire shall be used to fix the bells on each pillar。
Figure 3 cement pole planting
The north and the south are going to plant, the top of the pole is pierced 5 cm down, the north and the south are poignant, and the top is fixed at the top of each pillar; the top of the pole is traverse in the direction of east and west 40 cm down, connecting each pillar in the direction of east and west with a thicker steel winch, both of which are fixed at a 60 cm anchor. And draw from each side the edges of the shelter of 1. 1 metres north and south at the intersections of the two branches。
3. 2. Shed arch diameter
If the distance is 3 metres, the ventilation belt between the two sheds is to be kept at 30 to 50 centimetres, with a diameter below the bow of about 2. 5 metres。
3. 3. Upper shampoo
The cape is made of a bamboo chip or a suppressed hollow iron tube, 2. 5 metres long and a piece every 0. 6 metres, with the medium spot of the piece fixed on the top of the top, fixed on both sides and on the edges, and made up of the roof; when the roof is ready, it is able to go up to the sheet film; and when the upper membrane is completed, the wind is secured by a membrane cord。
4. Forming

4. 1. The first layer of the fowl
The first layer of wire, using concrete poles from the shelter, is at 1. 4 m above ground level (which can be controlled between 1. 2 and 1. 4 m depending on the owner's height and with a view to farming operations), using 30 to 40 cm cross-arms and pulling 2 wires。
4. 2. Flyingbird shelf, second layer of steel
The second layer of wire, on the cement pole, 15 cm from the first layer of wire, with a 70-80 cm stretch and two wires。
4. 3. The third layer of steel on the bird shelf
A third layer of wire, 15 cm from the second layer of steel wire on the concrete pole, with a carry of 1. 7 to 1. 8 m, pulling two wires。
4. 4. The fourth layer of steel on the bird shelf
The fourth layer of wire can hang on the beam, parallel to the third。
Note by the secretariat
The radians in 1 are not too large, the slopes of the bow are slightly steep, preventing heavy snow and crushing the shed。
The ventilation belt between the two huts, which is 30 to 50 centimetres, is too wide and easily causes sunburning of fruit and leaves; it is too narrow and the ventilation of light is not working well; depending on the terrain, it is easier to have sunburn than it is to travel east-south。
