Leveling the land before 65438+February, digging planting ditches according to the determined row direction and row spacing, with a width of 80 ~ 100 cm and a depth of 60 ~ 80 cm. Pay attention to the separation of topsoil and core soil when digging trenches. Apply base fertilizer, 3000 ~ 4000 kg of decomposed organic fertilizer and 0/00 kg of phosphate fertilizer/kloc per mu. Base fertilizer and planting ditch are applied in two layers, combining soil and fertilizer, filling core soil at the bottom and filling surface soil at the boundary.
2. Suitable planting period
Mid-March, that is, half a month before the temperature rises to the germination of grapes, is the suitable planting period.
The varieties with moderate row spacing should adopt double cross V-shaped frame, with row spacing of 2.5m, plant spacing of1.2 ~1.5m, and planting of 170 ~ 250 plants per mu. The vigorous varieties should adopt scaffolding, with row spacing of 3m, plant spacing of1~1.5m and planting of 150 ~ 220 plants per mu.
3. The planting method is to dig shallow holes according to the determined row spacing, and put the seedlings vertically into the holes, so that the roots are fully extended and evenly distributed in the holes. When cultivating soil, first cultivate half of the soil on the root system, then gently lift the seedlings upward to make the soil fully enter the root system, then cultivate the remaining soil, step on it steadily and pour it thoroughly.
4. Cultivation rack
A single hedge frame runs north and south, and a row of grapes has a hedge frame. The height of the hedge frame is 1.6 ~ 2m, and four iron wires are pulled on the frame, each with an interval of 0.5m. The first wire should be 0.6 ~ 0.8 meters from the ground, which can reduce the sensitivity of leaves and fruits to this wire.
The scaffold surface is parallel to the ground, and the column spacing is about 4 meters. At the place about1.8m from the ground, lay a steel wire grid with a length of 40cm in the vertical and horizontal directions. Around the column to tilt outward about 30 degrees, fixed with iron wire.
The upper beam of the double cross V-shaped frame100 ~10cm, the lower beam 160 cm off the ground, and the lower beam 1 10 cm off the ground, and a small hole is made at the edge of the two beams 5 cm. Pull two bottom wires on both sides of the pole 80 cm above the ground to form a double cross six wire frame.
Extended data
There are many excellent varieties of grapes, among which Kyoho, Fujiminori, Jingxiu, Meirenzhi, Ruby, Honey Juice, Hutai No.8 in Shaanxi and Tizi in Turpan, Xinjiang are suitable for cultivation in Northeast China.
Grapes are planted in fertile plots with good ventilation, sunshine and drainage. Spring sowing is mostly used in northern China, and it can be planted in the field in the middle and late April. Before planting, clean the dressing on the outside of the grafting interface with a sharp knife (after the grafted seedlings survive, the rootstock sprouted on the rootstock at the lower part of the grafting interface should be erased in time to ensure the purity and growth of the varieties), bury the planted seedlings in the soil so that the root neck can get enough water for planting, and then bury them in a small mound with fine soil to keep moisture and prevent drying, so as to make them germinate early.
