Method for planting wine grapes in gentle slope saline-alkali soil

According to the method for planting the wine grapes in the gentle slope saline-alkali soil, longitudinal ditches are formed in the downhill direction of the gentle slope saline-alkali soil, transverse ditches are formed in the downhill direction perpendicular to the saline-alkali soil, the depth of the longitudinal ditches and the depth of the transverse ditches are 1.5-1.8 m, the distance between the longitudinal ditches is 150-200 m, and the distance between the transverse ditches is 150-250 m; after furrowing is completed, water in the longitudinal furrows and the transverse furrows converges and flows into the downstream direction along the longitudinal furrows, after soil on the surface layer of the saline-alkali soil is scraped to 5 cm to 10 cm, grape planting furrows are formed in the direction of the saline-alkali soil and grape vine rows, the row spacing ranges from 3 m to 3.5 m, the width and the depth range from 1 m to 1.5 m, the planting furrows are filled and leveled up with soil for planting, t
