Embodiment 1

[0038] This example provides a method for improving saline-alkali land by using solid-liquid bio-organic fertilizer produced from slaughtering and breeding waste sewage and biogas residue from diseased and dead livestock and poultry. Bio-organic fertilizer is used as fertilizer and carried out in accordance with the following steps:

[0039] (1) Establish a grid management module: divide the saline-alkali land to be improved into grids, each grid size is 400m wide, and the length of each grid size can be extended until the terrain changes and it is not suitable for further extension. The 3-meter-wide working road is set up with drainage ditches according to the terrain. For the plots with an area of ​​more than 10,000 mu of saline-alkali land to be improved, a reservoir is set at the lowest depression of the saline-alkali land to be improved for drainage.

[0040] (2) Straw returning to the field: After harvesting in autumn, before applying base fertilizer and improving soil f...

Embodiment 2

[0045] This embodiment provides a method for improving saline-alkali land by using solid-liquid bio-organic fertilizer produced from slaughtering and breeding waste sewage and biogas residue from sick and dead livestock and poultry. The difference between this method and Example 1 is: step (3) Apply 5m per mu of moderate saline-alkali land to be improved 3 ~10m 3 solid bio-organic fertilizer and the covering thickness is not less than 0.7 cm, and the liquid bio-organic fertilizer of 15kg to 80kg is applied to the surface of the moderate saline-alkali land to be improved per mu; The amount of fertilization per acre of mild saline-alkali land to be improved in step (4) of Example 1.

Embodiment 3

[0047] This example provides a method for improving saline-alkali land using solid-liquid bio-organic fertilizer produced from slaughtering and breeding waste sewage and biogas residue from sick and dead livestock and poultry. The difference between this method and Example 1 is: Apply 7m in severe saline-alkali land 3 ~20m 3 The solid bio-organic fertilizer and the covering thickness are not less than 1 centimeter, and the liquid bio-organic fertilizer of 20kg~100kg is applied to the ground surface of each mu of severe saline-alkali land to be improved; in step (4), the fertilization amount of each mu of severe saline-alkali land to be improved is the same as that of Example 1 In step (4), the amount of fertilizer applied per acre of mild saline-alkali land to be improved.

[0048] For illustrating the control effect of the inventive method, carried out following experiment:

[0049] Experiment 1. Corn planting experiment in severe saline-alkali land

[0050] 1. Experimenta...

Abstract

The invention discloses a method for improving saline-alkali land by solid-liquid bio-organic fertilizer produced from slaughtering and breeding waste sewage and diseased and dead poultry straw biogasresidue and biogas slurry, and belongs to the technical field of saline-alkali land improvement. The method is to establish a grid management module; after the fall of the geogas and returning of thestraw to the field in autumn, the solid organic fertilizer and the liquid bio-organic fertilizer are applied to the mild saline-alkali land, the moderate saline-alkali land or the heavy saline-alkaliland that is to be improved, and after the rise of the geogas in spring, sowing is performed, the liquid bio-organic fertilizer is applied, and after the emergence of seedlings, the liquid bio-organic fertilizer is applied by foliar spraying or watering or drip irrigation; the steps are repeated for continuous non-stop cultivation management for 3 years to 5 years. The method of the invention canimprove the saline-alkali soil, does not require irrigation and salt elimination, and can fundamentally solve the problem of saline-alkali hardening, barrenness, no water storage, and almost no microorganisms.

Description

technical field [0001] The invention relates to a method for improving saline-alkali land with solid-liquid bio-organic fertilizer produced from slaughtering and breeding waste sewage and biogas residue from diseased and dead livestock and poultry, and belongs to the technical field of saline-alkali land improvement. Background technique [0002] There are about 99.13 million hectares of saline-alkali land in my country. Most of the formation of alkalized soil in China is related to the accumulation of soluble salts in the soil, which contains more water-soluble salts or alkaline substances. Most of the soil is compacted into lumps and has poor water permeability. It is mainly characterized by being sticky when wet, hard when dry, and poor air permeability. Due to the high salinity and high alkalinity, the content of humic acid and beneficial bacteria in the soil is extremely low; therefore serious In saline-alkali soil areas, plants can hardly survive. Saline-alkali land i...
