Embodiment 1
[0037] A comprehensive improvement method for saline soil, comprising the steps of:
[0038] S1, fertilization: add organic mineral fertilizer 200kg per mu, organic mineral fertilizer composition is: humic acid 10 weight parts, chicken manure 100 weight parts, calcium superphosphate 20 weight parts, ammonium sulfate 15 weight parts;
[0039] S2. Soil preparation: dig low and fill high, turn the fertilizer into the soil plow layer. Create an arc-shaped gentle slope every 5 meters, with a slope of 1%. An open ditch is excavated between the bottoms of the adjacent arc-shaped gentle slopes. The width of the ditch is 0.5 meters, the depth is 0.3 meters, and the longitudinal slope of the open ditch is 0.5%, so that the salt water can be discharged ;
[0040] S3, pipe laying irrigation: the slope top of the arc-shaped gentle slope is laid with a rotating micro-spray nozzle, and the spray radius is adjusted to 0.1 meters according to the pressure, and then permeable irrigation is car...
Embodiment 2
[0047] A comprehensive improvement method for saline soil, comprising the steps of:
[0048] S1, fertilization: add organic mineral fertilizer 250kg per mu, 15 parts by weight of humic acid, 110 parts by weight of chicken manure, 23 parts by weight of superphosphate, 18 parts by weight of ammonium sulfate;
[0049] S2. Soil preparation: dig low and fill high, turn the fertilizer into the soil plow layer. Create an arc-shaped gentle slope every 8 meters, with a slope of 4%. An open ditch is excavated between the bottoms of the adjacent arc-shaped gentle slopes. The width of the ditch is 0.8 m, the depth is 0.4 m, and the longitudinal slope of the open ditch is 1.5%, so that the salt water can be discharged ;
[0050] S3, pipe laying irrigation: the slope top of the arc-shaped gentle slope is laid with a rotating micro-sprinkler, with a spray radius of 1.0 meters, and then permeable irrigation is carried out;
[0051] S4, sowing Suaeda salsa: sowing in early March, 1.3kg of se...
Embodiment 3
[0057] A comprehensive improvement method for saline soil, comprising the steps of:
[0058] S1, fertilization: add 300kg of organic mineral fertilizers per mu, 20 parts by weight of humic acid, 120 parts by weight of chicken manure, 25 parts by weight of superphosphate, and 20 parts by weight of ammonium sulfate;
[0059] S2. Soil preparation: dig low and fill high, turn the fertilizer into the soil plow layer. Create an arc-shaped gentle slope every 10 meters with a slope of 6%. An open ditch is excavated between the bottoms of the adjacent arc-shaped gentle slopes. The width of the ditch is 1 m, the depth is 0.5 m, and the longitudinal slope of the open ditch is 3% to facilitate the discharge of salt water. ;
[0060] S3, pipe laying irrigation: the slope top of the arc-shaped gentle slope is laid with a rotating micro-sprinkler, and the spray radius is adjusted to 0.1-1.5 meters according to the pressure, and then permeable irrigation is carried out;
[0061] S4, sowing ...
