(I) Selection and planning of gardens Grapes are highly adaptable. They are warm, happy, and sandy. They are suitable for going down the mountain and entering the village. They are the preferred tree species for the rural courtyard economy. Areas such as mountains, floodplains, and salt and alkaloids can be used to develop grapes after improvement. The large-scale construction of the park mainly considers local climate zones, makes full use of natural resources such as light, heat, and soil, avoids weaknesses, and exerts advantages. The establishment of vineyards for processing varieties pays particular attention to the requirements of the processing plants, and should not be blindly developed.
The planning principle of the vineyard is roughly the same as that of other fruit trees. It also includes the division of the community, the planning of roads and irrigation and drainage systems, and the construction of ancillary facilities. In practice, according to the biological characteristics of the grape and the local topography, soil, climate and other conditions, eclectic, flexible use.
(2) Pre-planting soil preparation Grapes are deep-rooted crops. Before the planting, the soil must be deep-ripened, matured and improved to create suitable growth conditions for the root system so that the plants can maintain their robustness and achieve stable production and high yield.
Most of the old grape growing areas in China use local methods of deep plowing and custom soils; in the establishment of vineyards on flat grounds, digging belts are used to improve the soil.
(3) Planting density The factors affecting the planting density of grapes mainly include climate, soil and fertility conditions, species, shelf type, pruning methods and management methods. In cold regions, it is necessary to install large-scale rows to facilitate over-wintering, and there is a small gap between areas that do not need to be buried in winter. Soil fertility and water conditions are good, varieties grow vigorously, and scaffolding is used for cultivation. The row spacing should be large; the row spacing using fences can be small. The current production line spacing is shown in Table 4-1.
(D) The colonization of the north is generally planted before and after the budding of the grapes, in Shandong around around mid-April. The orchards that cover the mulch after planting the seedlings may be planted one week earlier than the orchards that cover the mulch. Film coverage is not only conducive to the early growth of grapes, but also can significantly improve the survival rate of planting. Areas with water shortages must be buried in shallow trenches.
Before planting, 2-3 shoots of the aerial part of the seedlings were cut off, and then they were disinfected with 5 Baumide Lithosulphide, and the roots were finely pruned to expose new shoots, and the length was 15-20 cm. When planting, the root system will be stretched. 2-3 buds will be left on the surface of the seedlings to expose to the surface of the lotus root. Irrigation will make the root system and the soil close. The branches exposed on the surface of the earth are covered with wet sand or sandy loam, and the thickness of the cover soil is about 3-5 cm. The arid and semi-arid regions are very dry in early spring. The air humidity is low, and the thickness of the cover soil can be increased to 10-15cm. When germination occurs, a part of the cover soil can be removed to a distance of 3cm from the shoots. Do not cover clay.
When planting grafted grafts of cold-resistant rootstocks in the northern region, the shoots on the ground must be 20-30cm thick, and they should be planted obliquely in planting holes when planting. With an inclination angle of 30-45, wet soil is used to embed the anvil section and the upper scion section in the soil so that the apical shoots are 3-5 cm from the top surface of the soil pile. After the new shoot reaches 20cm, the mound is removed and the anvil section is exposed.
