(1) Choose varieties that are edible, robust, suitable for shed cultivation, relatively disease-resistant, excellent in fruit quality and beautiful in appearance; Such as longan, milk, red heart, giant peak, white banana and so on.
(2) For planting in the courtyard, a pit with a depth of 0.8~ 1.0 m can be dug under the north wall or on the east and west sides of the courtyard wall at a distance of 1~ 2 m, and weeds, orange stalks and other organic substances can be applied to the bottom of the pit, mixed with poultry manure and pigsty fertilizer. If you are on both sides of the road, you can dig ditches. When the groundwater level is shallow or the soil is poor, you can also change the soil and apply organic fertilizer in the planting pool with the height of 1 meter and any length.
(3) The scaffold is the most type, and the size of the scaffold surface depends on the size of the open space and light. Institutions, schools, factories and other units have wide roads. In order to facilitate the passage of vehicles, it is necessary to erect a horizontal or arched frame with high height, large span and firm support.
Urban residential areas are mostly small yards or buildings, with small front doors, which can be developed to high altitude. The space behind the front room and back room of rural residence can be designed according to local conditions.
Second, potted grapes, potted grapes are different from ordinary cultivation, and the cultivation techniques are special. In general, the following links should be considered:
(1) Choose fresh food varieties with big ear, big grain, beautiful color and many fruits, such as Saba Pearl, Yannong No.1 and Zaogui, which are early-maturing varieties. The middle and late maturing varieties are. All kinds of all-around black lights.
(2) Choose a matching basin, generally choose a pottery pot with a diameter of 30-40 cm, which has good drainage and air permeability. In addition, you can also use other containers, such as bamboo baskets or wicker baskets, sew the bottom with moss, and put them in culture soil to grow grapes.
When preparing pot soil, it is necessary to make the pot soil have the characteristics of maintaining fertilizer, water and air permeability as much as possible. Potted soil is light sandy loam or fertile garden soil, and fermented animal manure or human manure, cake fertilizer, calcium superphosphate and high sugar ash are added.
(3) planting. There are three planting methods: cutting into seedlings, pressing vines and cutting planting.
Planting seedlings: cutting 2-3-year-old seedlings and selecting single plants with full branches and high seed setting rate; Cut off the annual seedlings and leave 1~ 2 buds. No matter how big or small the seedlings are, try to keep the roots and stick them in the pot.
Pressing vines: select vines that are fully mature and bear fruit, prepare the pot soil, then insert the pressed vines into the pot from the seepage holes at the bottom of the pot, and cut off the internodes buried in the soil, so as to leave 2-3 branches at the top of the root pot, and take out new vines from 2-3 leaves at the top of the spike to control their growth. After more than three times of gradual pruning, the branches and vines are cut off together with the mother branches (pruning), which prevents the supply of nutrients and forces the layering to take root. After about 20 days, it was cut again at the cutting place. The last time is layering to take root, cut it once or twice.
