Embodiment 1

[0021] (a) Ditching terrace fields: Excavate a salt drainage ditch 2 every 15 m in the flat coastal heavy saline-alkali land, with a width of 3 m, so that the relative height difference between the top of the terrace 1 and the bottom of the ditch reaches 1.5 m;

[0022] (b) Flood irrigation: dam 3 around the surface of the terrace, and use fresh water 4 to irrigate terrace 1 with an irrigation volume of 150 mm;

[0023] (c) Increase the application of organic fertilizer: when the surface of the terrace 1 is flooded with water and naturally infiltrates, spread the decomposed farmyard manure on the surface of the terrace 1;

[0024] (d) Ridge: Rotary tillage after fertilization, ridge 6, ridge height 10 cm, ridge width 58 cm;

[0025] (e) Membrane covering: at the same time of ridge formation, plastic film 7 is used to cover the surface of ridge 6, and drip irrigation tape 8 is laid under the film;

[0026] (f) Sowing: On March 20, 2011, a puncher was used to drill holes on rid...

Embodiment 2

[0033] (a) Ditching terrace fields: excavate a salt drainage ditch 2 every 20 m in the flat coastal heavy saline-alkali land, the ditch width is 5 m, so that the relative height difference between the top of terrace field 1 and the bottom of the ditch reaches 2 m;

[0034] (b) Flood irrigation: dam 3 around the surface of the terrace, and use fresh water 4 to irrigate terrace 1 with an irrigation amount of 200 mm;

[0035] (c) Increase the application of organic fertilizer: when the surface of the terrace 1 is flooded with water and naturally infiltrates, spread the decomposed farmyard manure on the surface of the terrace 1;

[0036] (d) Ridge: Rotary tillage after fertilization, ridge 6, ridge height 12 cm, ridge width 60 cm;

[0037] (e) Membrane covering: at the same time of ridge formation, plastic film 7 is used to cover the surface of ridge 6, and drip irrigation tape 8 is laid under the film;

[0038] (f) Sowing: On March 22, 2012, a puncher was used to drill holes on ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a high-yield cultivation method for potatoes in coastal heavy saline-alkali land. Background technique [0002] There are about 1.5 billion mu of various saline soils in my country, accounting for 26.3% of the world's saline soil area. The coastal and inland areas have a large area of ​​saline-alkali land, and most of the saline-alkali land has been waiting for development. In particular, heavy saline-alkali coastal areas have high groundwater levels, high soil salinity, soil compaction, low soil fertility, and poor air permeability, making it difficult to produce various economic crops. potato[ Solanum tuberosum L.] is the fourth largest grain crop in the world after rice, wheat, and corn. It has extremely high yield and nutritional value, and is an important economic crop. Potatoes are suitable for growing in acidic soils with a pH value of 5.5-6.0. In high-...
