How to lay the film of the grape rain shelter, can the grape rain shelter be insulated with two film

1) Bamboo structure rain shelter.

Traditionally, the rows of vineyards are spaced 3 metres apart, and the ground is separated by a 30 cm wide ditch that is deep enough to facilitate drainage. The top of the shelter is high meters, and the shelter is built above the meter, the width of the shed is meters, and the height of the shed is meters. The roof and the edge of the shed are fixed with wooden strips, and the bamboo pieces are made into a bow shape.

Nail 1 piece of bamboo every 50 cm. The bamboo sheet is covered with film, the film thickness is millimeters, every 50 cm with a laminating film line (can be replaced by a machine packaging tape), and the width of the film is appropriate to cover the edge of the shed or slightly wider.

Each single frame plus two cross arms (beam), 140 cm from the ground to frame the first (60 100 cm long), 180 cm from the ground to frame the second (120 160 cm long), beam can be steel pipe or miscellaneous wood strips or thick bamboo, etc. Each single frame has three layers of six wires, the first layer is 80 100 cm above the ground, and two lanes (around the column); The second layer of iron wire and the third layer of iron wire are fixed at both ends of the cross arm respectively, and the No. 10 iron wire or the corresponding thickness of steel strand are generally used. The end post is 12 cm 12 cm (270 300) cm, buried in the soil 60 cm, and the anchor stone is buried in the soil with wire or the column is used as a side support to prevent collapse.

The middle column is 10 cm 10 cm (270 300) cm, the fixed place of the cross arm can leave 1 hole to pass through the wire, the column spacing is 4 8 meters, and the middle column is buried in the soil 60 cm.

2) Steel structure rain shelter.

In recent years, galvanized steel tube plastic greenhouses or multi-story plastic greenhouses have been promoted in various places to cultivate grapes in a large-scale rain shelter. The technology of facility design, construction and viticulture facilities has become increasingly sophisticated.

You should be talking about rain shelter cultivation. In the southern region, there is a lot of rain in summer, and many grape diseases are spread by wind and rain, and the general quality of Eurasian grapes with poor disease resistance is poor, and the use of rain shelter cultivation can make some Eurasian grapes with poor disease resistance avoid rain, so as to reduce the diseases spread by wind and rain, and produce high-quality grapes in rainy areas. 9111

OK. The rain shelter is an arched shelter made of stone pillars, bamboo chips, steel frames, iron wires, and plastic sheets built on the upper part of the grapes. Among them, the stone pillar and steel frame play a supporting role, and the bamboo sheet and steel frame play a fixed role.

Although the one-time consumption cost of the rain shelter is high, it is effective. First, it interrupts the spread of pathogens. Some germs will be splashed with rainwater on the wounds and fruits of the tree, causing various diseases.

The rain shelter can block all the rainwater in the upper part of the grapes, so that the rainwater flows down the edge of the canopy to the middle open space, so as to reduce the dripping of rainwater, thus reducing the chance of fruit disease.

Grape pests and diseases have been reduced, which means that pesticides have been used less frequently. The use of rain shelters not only ensures the quality of the fruits, but also reduces the degree of air pollution. Compared with the cost of pesticides spent on diseased grapes over and over again, building a rain shelter may be more cost-effective, durable, labor cost and workload.

There must be a reason why canopies are widely used over a large area, and planting experiments have proven that the grapes in the canopies are generally healthy. The soil in the shed has a higher moisture content and the trees are healthier. In addition to reducing the incidence of grape pests and diseases, the rain shelter can also control the amount of water in the soil, the leaves are greener and more intact, the probability of fruit cracking is reduced, and the sugar content is higher and the quality is better.

Rain shelters generally have a triangular structure. The length of the column is about two meters eight, the lower part of the column is buried 50 centimeters deep underground, the longer the underground is buried, the more stable the scaffolding, but the above-ground part should be retained at least two meters two, and the height of the scaffolding should be higher than the height of the farmer, which is convenient for field management and operation. There should be a sloping pillar next to the column to support the column.

The highest point of the inclined column cannot exceed the pull line at the highest point of the column. There are three steel wires on each column. The wire is made of galvanized steel wire, which plays a windproof and stable role. The lowest part of the cable should be 40 centimeters from the ground, and the highest part of the cable should have a bow made of iron wire.

The grapes are planted in the greenhouse to increase the temperature at the beginning of the growing season, not to be afraid of rain, and it is useless to have a canopy.

Rain shelters are mainly disease-proof, especially varieties such as red grapes, which have great benefits.

Shelters are needed in rainy areas in the south, and can also be planted in the open air in the north.

Hello, I am very happy to serve you in the grape rain shelter can be insulated with two membranes pro 1, as far as the material is concerned, the old closed grape rain shelter film with polyethylene film, polyvinyl chloride film, vinyl acetate film can be, but with longevity, no dripping, anti-aging and good light transmittance of vinyl acetate film and polyvinyl chloride film is better. As far as the film color is concerned, white is better to facilitate light transmission. In terms of thickness, the narrow shed should be silk), and the wide shed should be silk.

2. During the mulching period, it should be noted that the greenhouse film should be rolled up, so that the plants can receive more sunlight and dissipate the stuffiness, so as to enhance photosynthesis, accumulate nutrients, and improve the coloring and quality of the fruit and the leaky state.

To build a grape trellis you need to start from the aspects of site selection and planning, trellis materials, construction specifications and construction techniques. Choose a place with sufficient sunlight but not too strong to build a shed, use wooden or iron poles as materials, build a curved shed or a straight shed, and build a complete and laminated one after another.

1. Site selection planning

Before building a grape trellis, we must first choose a suitable address, the first thing to consider is the light situation, whether it is a large-scale breeding base grape trellis or an ordinary grape trellis used in furniture, we must choose to build in a place with sufficient light, but there are shading means, so that it can receive suitable light.

2. Scaffolding material

The materials used in grape trellis are generally iron or wood, iron is suitable for long-term, large-scale and uniform grape planting, while wooden is suitable for small-scale garden planting, whether iron poles or wooden poles must be treated with anti-corrosion or anti-rust to prolong the use time.

3. Building specifications

No matter what kind of scaffolding you plan to build, you must first measure the size, in a limited space, accurately plan the distribution of the scaffolding, its length, width and other data must be measured and estimated, and leave a certain amount of empty space, the general base scaffolding is based on the round vault, and the courtyard scaffolding is mainly based on the square flat top.

4. Construction techniques

The prepared poles are cut and trimmed one by one according to the distance measured and estimated before, and arranged according to the length, width and height according to the previous planning, and the fixed construction of a group of groups, tightening the screws, etc., and covering with a transparent film after the construction is completed to prevent rainwater from seeping in.

How to build:

The rain shelter is composed of canopy columns, beams, arches, canopy films, pull wires, etc.

The shed is one meter wide, the bow is one meter high, and a bow-shaped bamboo piece or 1 cm thick bamboo pole is fixed every 1 meter.

Bamboo slices or bamboo poles are meters long.

Buckle film in late May. The two sides of the membrane are fixed on the bamboo pole or steel wire with clips, and the membrane can be fixed with a film wire every 1 meter above the membrane. Remove the film after harvesting in late September. The thickness of the membrane should be in millimeters.

The width of the canopy is equivalent to the width of the leaf curtain or 10 cm wider. The canopy is 30-50 cm above the leaf curtain.

To build a rain shelter, bamboo chips or bamboo poles with a thickness of 1 cm are required, and beams (can be replaced by 10 gauge steel wire).

Grapes do not need to build a rain shelter, grapes are not afraid of watering, the more rain the better

High and compliant with the legalization of the house.

Hello, the following is a little sister to solve your doubts for you, I hope it can help you. Kiss, grape canopy is not unloaded in winter, and the time of covering and uncovering the film mainly considers two factors: disease and light. The film cover time is set in mid to late May before flowering, with the main purpose of protecting flowers and fruits, and at the same time not allowing the growth of new shoots before flowering to be affected by film shading, which is suitable for European and American hybrids.

For Eurasian grapes, due to the serious damage of black pox in early spring, the film capping time should be advanced to the end of March and early April of the budding stage, which is conducive to disease prevention. I really hope I can help you, and I wish you happiness every day!
