What are the cultivation techniques of Xinyu grape?

Xinyu grape is a hybrid variety of Hongti and Rizamat, which is a mid-late ripening grape variety with high and stable yield and strong fruiting ability. it generally matures in late August. The following is to introduce its cultivation techniques.

Cultivation techniques of Xinyu Grape

1. Land preparation

On the basis of deep ploughing in autumn and ripening soil by winter irrigation, the whole garden was ploughed again at the end of March and the first ten days of April of the following year, then leveled the bed, opened a planting ditch with a width of 1.2 meters and a depth of 0.2 meters according to the row spacing of 2.75 meters, and opened a planting pit in the middle of the planting ditch. The planting pit is 60 cm deep, 60 cm in diameter or 60 cm wide and 60 cm deep. Before planting, 800 kg of dung, cattle and sheep manure and 120 kg of superphosphate per mu were mixed with several times of topsoil and evenly applied into the pit or ditch to fill the bottom water.

two。 Planting

Choose the best planting time according to local weather and climate conditions. The seedlings should be pruned properly before planting, cut off the dead piles, the planting depth should not be too deep or too shallow, the roots of the seedlings should be scattered around, covered with soil, irrigated once after planting, and then covered with soil after water infiltration to keep the roots from being exposed.

3. Build a shed

According to the local topography to build scaffolding, the general topography is more complex areas can use funnel scaffolding (sector scaffolding), the general area can be horizontal scaffolding, roof-ridge scaffolding and so on.

4. Fertilizer application

In addition to applying sufficient basal fertilizer, it is generally necessary to topdressing 2-3 times a year in high-yield orchards during the grape growing season. The first topdressing was carried out when the early spring bud began to expand; the second topdressing was carried out at the early stage of fruit expansion after flowering, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer; and the third fertilization was carried out at the initial stage of fruit coloring, mainly phosphorus and potash fertilizer. the amount of fertilizer applied accounts for about 10% of the amount of fertilizer used in the whole year.

5. Pruning

In addition to inflorescence pruning, ear arrangement should be carried out for fresh varieties, and the time of ear arrangement should be carried out after the physiological fruit drop is basically stable.

6. Intermediate ploughing and weeding

Middle ploughing is the soil tillage carried out during the grape growing period, and the middle tillage should be shallow, usually 3-4 cm. After irrigation or rainfall, the soil should be ploughed and loosened in time to prevent soil consolidation and water evaporation. It can be ploughed 6-8 times throughout the year. The removal of weeds in vineyards during the growing season is an important management work, and mid-tillage and weeding should be combined.
