What should be paid attention to in the latest planting of Vitis amurensis

With a wide variety of grapes, grapes are now the main fruit and dried snacks commonly sold. Vitis amurensis is an important wild economic crop, which has attracted a lot of investment or planting in large areas in recent years. So what are the details that we should pay special attention to you in the process of planting mountain grapes? I will enumerate and explain them one by one.

I. Establishment of a garden

Choose the leeward and sunny soil for planting. In autumn or early spring, dig the planting line which is about 0.5 meters wide and about one meter wide, leaving a ditch of about 15 centimeters to facilitate drainage and irrigation. After digging, the dug soil will be mixed with fallen leaves, and the base fertilizer will be added to the row as a nutritious soil for cultivation. It is planted by the way of fan-shaped scaffolding, otherwise the disease is infected by rainfall.

II. Colonization

Choose a longer stem, more purebred grafted seedlings, the best stem thickness of more than 0.5 cm, plant height of 80 cm. The buds are full and the internodes are short and thick. The planting time must be from April to May. Autumn planting should be carried out before the frost. The root system can be soaked with rooting powder and water before planting, so as to take root quickly after planting and to restore the root system. Planting pits are generally one meter deep and wide. First fill back the subsoil mixed fertilizer, and then water some topsoil and base fertilizer at one time, put in the seedling, one hand to support the seedling, while backfilling the soil, and then tread on the soil again, help the seedling to lift the seedling to pour water, in the soil to the root neck, even if the planting is finished.

III. Management

1. Fertilizer and water

Base fertilizer is the use of farm organic fertilizer, usually before the autumn frost. Topdressing was carried out by stages: 15.0kg urine + 7.5kg calcium superphosphate + 15kg potassium sulfate at budding stage, 20 kg+ per mu of urea at one mu before flowering, 10kg calcium superphosphate + 20kg potassium sulfate. Results A certain amount of phosphate fertilizer was needed before discoloration. If the stem is unable to climb, you need to use some plant ash to supplement potash to strengthen the stem. The grapes should be watered once before sprouting, once before flowering, once in the period of fruit coloring, once in freezing before cold protection in winter, and then buried after the water seeps into the soil. Generally, the flowering period can not be watered, which is not conducive to flower protection.

two。 Guard against cold

From October to November, cultivate the soil to protect against the cold, take the soil from far away from the root to beat fine disinfection, add rotten farm manure and stir and pour it at the base of the root, covering the soil to about 20 cm of the stem in order to effectively prevent the cold. The soil was slowly dug off when the soil warmed up the following spring.

The problems that need to be paid attention to in the planting of mountain grape are mainly the above points, although there will be various details in the actual production. But I believe that most of the problems can be avoided by doing what is said above.
