Grape supports commonly used in production include cement columns, stone columns and wooden columns. In some arid and rainy places in the north, there are also no-support and no-frame cultivation. In some areas, in order to save the cost of garden construction, the existing trees in the garden are used as living piles. What kind of support should be used specifically should be based on local actual conditions and local conditions. But no matter what material is used, we should pay attention to the firmness of the pole.
1. The total length of cement pile is 2.5-2.6m, and the diameter is12cm2. When making, leave four holes (for iron wire) at 0.5 m, 1.0 m, 1.5 m and 2.05 m on the ground, and the bottom of the cement pile should be buried in the soil for 50-60 cm. Generally, a cement pile is erected every 8- 10 meter in the planting line, and about 40 cement piles are needed every 666.7 square meters.
The column is 2.5m long and12-15cm in diameter. Before use, the part of the lower end of the pile buried in human soil should be coated with asphalt. Asphalt can be used for 3-4 years after treatment, otherwise it can only be used for 1-2 years. The amount of wooden poles is the same as that of cement columns.
3. Shelf-free cultivation is only suitable for arid areas and some upright varieties, such as red roses. In fact, frameless cultivation is to cultivate grape plants into upright trees by means of shaping and pruning, but some short columns are still needed to support them after fruiting. In order to improve the yield and quality of grapes, trellis cultivation should be carried out wherever possible, which is not only convenient for field management, but also can fully extend the trellis surface and make maximum use of light energy and space. The supports used for grapes in the courtyard can be flexibly determined according to the buildings and trees in the courtyard.
