Problems solved by technology

At present, the main measures for improving saline-alkali land include physical methods, chemical methods, and biological methods, among which, no matter whether it is the method of simply using chemical or biological modifiers, or the method of simply using physical salt discharge, the improvement effect on saline-alkali land is not high: simple Using improvers to control saline-alkali land, the salt is not easy to discharge, and it is easy to cause problems such as soil compaction, affecting crop growth and subsequent fertilization operations. Simply using physical salt discharge, free salt can be discharged, but the salt combined in the soil cannot be fully analyzed. And serious waste of water resources

preparation example 1

[0026] The preparation method of the conditioner fertilizer of improving saline-alkali soil, the steps are: get wood vinegar to dilute, aluminum sulfate, urea, polyacrylamide, phosphogypsum, diammonium phosphate, potassium sulfate are added in the wood vinegar dilution, mix uniformly, Obtain mixture A; crush the biological bacterial fertilizer, biochar, and bacterial chaff, and mix them uniformly to obtain mixture B; mix mixture A and mixture B evenly, place for 12 hours, stir once thoroughly, and place for another 12 hours to obtain the conditioner for improving saline-alkali land soil Fat (a).

[0027] Grinding to 80 meshes; the dilution factor of wood vinegar is 700 (V / V) times.

[0028] The mass ratio of aluminum sulfate, urea, polyacrylamide, wood vinegar, phosphogypsum, diammonium phosphate, biological fertilizer, potassium sulfate, biochar and bacterial chaff is 1:1:1:5:4:2:4: 2:10:10.

[0029] The storage temperature is 4°C, the compost size is 1.2m×1.2m×1.2m, and th...

Embodiment 1

[0041] A method for improving saline-alkali soil, specifically:

[0042] 1. Sprinkle the conditioning fertilizer (a) for improving saline-alkali soil evenly on the soil surface and bury it;

[0043] 2. Digging several trapezoidal channels that are parallel to each other and whose cross-section is wide at the top and narrow at the bottom, forming a structure in which wide ridges and channels are arranged alternately;

[0044] 3. Water on the ridge, mulch, remove the film, water several times, and then drip wood vinegar.

[0045] Conditioning fertilizer dosage is 1Kg / m 2 ; The burial depth is 10cm.

[0046] In order to avoid waste of resources, use the ground location of the conditioning fertilizer to avoid the location of the pre-excavation channel.

[0047] The upper side of the channel cross section is 20cm long, the lower side of the cross section is 10cm long, and the cross section is 10cm high. The distance between the closest two sides of two adjacent channels is 0.5m...

Abstract

The invention discloses an improving method of saline-alkali land soil and relates to the technical field of saline-alkali land soil improving. According to the specific scheme, the improving method comprises the steps that conditioning fertilizer for improving the saline-alkali land soil is uniformly scattered on the surface of the soil, and turning burying is conducted; a plurality of mutually-parallel channels are excavated; and watering and film covering are conducted, film removing is conducted, watering is conducted for multiple times, and then dripping irrigation of wood vinegar is conducted. According to the improving method of the saline-alkali land soil, chemical improvement, biological improvement and physical improvement are organically combined, so that the optimal improvementeffect is achieved, and the problems that in chemical improvement, the soil is hardened, subsequent operation is affected consequently, in biological improvement, the cost is high, the consumed timeis long, and in physical improvement, resource waste is serious are also avoided; and through the improvement method provided by the invention, the soil is not hardened, soil fertility is balanced, the soil is suitable for crop growth, and the salinity and the pH value of the soil are decreased to the maximum extent on the basis of saving resources.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a method for improving saline-alkali soil. Background technique [0002] The formation of saline-alkali land in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. At present, the main measures for improving saline-alkali land include physical methods, chemical methods, and biological methods, among which, no matter whether it is the method of simply using chemical or biological modifiers, or the method of simply using physical salt discharge, the improvement effect on saline-alkali land is not high: simple Using improvers to control saline-alkali land, the salt is not easy to discharge, and it is easy to cause problems such as soil compaction, affecting crop growth and subsequent fertilization operations. Simply using ph...
