Transverse-ridge double-row micro-spraying interception type drought-resisting potato cultivation method

The invention belongs to the technical field of potato cultivation, and discloses a transverse-ridge double-row micro-spraying interception type drought-resisting potato cultivation method. Soil preparation, ridging and sowing are performed, a micro-spraying pipe belt is laid, auxiliary fertilization management is performed, field water spraying irrigation is performed, water spraying irrigation is performed after potato sowing is completed for 2-3 days, and water spraying irrigation is performed for 3-5 times from the full-bloom stage to the mature harvest stage. During each time of water spraying irrigation, an earth ridge with the height of 10-15 cm in a furrow performs blockage for interception irrigation, so that the earth ridge performs blockage intactly; and a hole is directly punched in a film when plastic film mulching occurs at the bottom of the furrow, so that intercepted water during each time of water spraying irrigation can immerse and wet a potato planting ridge. The method solves the problem t
