When planting in the courtyard, you should choose a sunny, dry and well-drained place. Because grapes like sunshine, the lack of light forms slender internodes, and the ears are few and the grains are small, which affects the ornamental and quality. In addition, build large scaffolding or small scaffolding. Replacing columns with courtyard walls can not only save frame materials, but also be used as a arbor, and can also use the dense branches and leaves of grapes to shade the summer. Under the shed, we can develop aquaculture, plant flowers and vegetables, make full use of courtyard space and develop three-dimensional planting. The specifications of general scaffolding are as follows: large scaffolding: frame length 10 ~ 15 m, plant spacing 1 ~ 3 m, frame height 2 ~ 22 m, roof with 8 ~ 10 lead wire horizontally drawn into a grid of 50 cm and 50 cm. Generally, fan-shaped pruning with multiple main vines is adopted.
Small scaffolding: generally inclined. The frame length is 3 ~ 6m, and the plant spacing is 1 ~ 2m. The height of the back of the frame is about 0.5 ~1m, and that of the front beta card is 18 ~ 22m. This posture leads to early plastic surgery.
When potted grapes, the pot soil should be fertile, not cracked when dry, not sticky when wet, not hardened after watering, and have good water and fertilizer retention performance. The proportion of potted soil can be 5 parts of fermented and decomposed sawdust, 2 parts of vegetable garden soil and 3 parts of decomposed manure, or 5 parts of cinder, 3 parts of decomposed soil and 2 parts of decomposed manure.
Because the nutrients in potted soil are limited, the amount of branches left should not be too much and the plant shape should not be too big. The principle of plastic trimming is: small and compact play, beautiful shape, generous and elegant.
