The invention relates to the technical field of agricultural production, and particularly provides a coastal heavy
saline-alkali land potato high-yield cultivation method. According to the coastal heavy
saline-alkali land potato high-yield cultivation method, a series of technical measures including ditching for a raised field, basin
irrigation, additional
organic fertilizer application, ridging, film covering, seeding, under-film adjustment acid
drip irrigation and the like are adopted, a high yield of potatoes in a coastal heavy
saline-alkali land is realized. The coastal heavy saline-alkali land potato high-yield cultivation method has the advantages that through the ditching for the raised field, the underground
water level can be lowered; through the basin
irrigation, salt materials in soil can be subjected to leaching; through the additional
organic fertilizer application,
soil fertility can be enhanced, and soil microbial communities are increased; through the ridging, the film covering and the under-film adjustment acid
drip irrigation, the salt materials on ridges are further subjected to the leaching,
evaporation is reduced, and the surface aggregation property of the salt materials is eliminated; and
irrigation water is used for adjusting potential of
hydrogen, an environment more suitable for growth of the potatoes can be created, and
disease occurrences can be reduced, and therefore the high yield of the potatoes in the coastal heavy saline-alkali land is realized.
