Planting mountain grape requires cutting or grafting seedlings, and then arrange the planting density. The pruning of mountain grape in winter and summer is mainly based on branches and buds, and the rate of fruit setting can be increased by equipped with pollination trees. Vitis amurensis has poor resistance to downy mildew and gives priority to prevention in management.

Planting method of mountain grape

First, raising seedlings

1. Cutting seedlings: it is difficult for mountain grape cuttings to take root and survive, but soaking cuttings with 100ppm-200ppm 's sodium naphthalene acetate and keeping them at 25-30 ℃ for 24 hours, the rooting rate of cuttings can reach 85%, 90%, which is 20-40 times higher than that without chemical treatment. When using this method, the temperature should not be too high or too low, otherwise it is not easy to take root or die.

two。 Grafting seedlings: collect mountain grape seeds, sow seedlings, graft bisexual Huashan grape varieties; you can also use Beida rootstock to graft excellent mountain grape varieties.

Second, increase the rate of fruit setting

The main way to increase the fruit setting rate: equipped with pollination trees, the planting ratio of complete Huashan grape to male plants is 5:1 or 3:1, the effect of natural pollination is good. Spraying 0.3% boric acid solution at flowering stage can increase the fruit setting rate by 66.7%.

III. Prevention and control of diseases and pests

Bordeaux solution can be sprayed before the rainy season in late June. After that, Bordeaux solution can be sprayed every 7 ∽ every 10 days, and its concentration is 180 ∽ 200 times. If the disease occurs, it can be sprayed with 300 times aqueous solution of 40% ethyl aluminum wettable powder, which has a good therapeutic effect.
