The invention discloses a planting method using under-film drip irrigation in saline-alkali land, which at least includes the following steps: (1) Ridging the land: forming water collecting ridges on the leveled land to be sown (4), the ridge distance is 180 cm or 240 cm, and the ridge distance is 180 cm or 240 cm. 10-15cm high, ridge width 30cm; (2) Seeding, pipe laying and film laying: longitudinally sow, pipe laying and film laying between the water collection ridge (4) and the water collection ridge (4), when the distance between the ridges is 180cm, take a film The mode of two tubes and four rows is used to sow seeds in wide and narrow rows, with a width of 60 cm and a narrow row of 30 cm. The drip irrigation tape (2) is laid in a narrow row with a tube distance of 90 cm; or when the ridge distance is 240 cm, one film, two tubes and six rows are used. The pattern is carried out operation, adopts equidistant sowing, row spacing 60cm, pipe spacing 120cm, drip irrigation belt (2) distance near water collection ridge (4) 90cm. Compared with the prior art, the present invention has the advantages of improving the utilization rate of water resources, preventing "rainfall dead seedlings" and the like. |
