Embodiment 1
[0060] A comprehensive method for biological improvement of saline-alkali land, characterized in that the specific steps are as follows:
[0061] Step 1, deep plowing and plowing, deep plowing the saline-alkali soil twice with a tiller, the plowing depth is 30cm; loosen the soil, increase the permeability and porosity of the soil; expose to the sun, expose the soil after each deep plowing for 2 times, 10 days each time, to promote soil loosening and the precipitation of saline-alkali components;
[0062] Step 2, drilling wells, averagely every 2000m 2 Setting up a deep well can effectively lower the groundwater level and lay the foundation for the next step;
[0063] Step 3, build high-pressure saline-alkali, with an average of 80m 2 Build a high ridge, the ridge is 40-50cm high, and then inject it with a water height of 20cm, once, 10 days each time, use the dissolution and dilution of water to dissolve the saline-alkali components in the soil, discharge it into the ditch, ...
Embodiment 2
[0069] A comprehensive method for biological improvement of saline-alkali land, characterized in that the specific steps are as follows:
[0070] Step 1, deep plowing and plowing, deep plowing the saline-alkali soil twice with a tiller, the plowing depth is 35cm; loosen the soil, increase the permeability and porosity of the soil; expose to the sun, expose the soil after each deep plowing for 2 times, 15 days each time, to promote soil loosening and the precipitation of saline-alkali components;
[0071] Step 2, drilling wells, averagely every 2500m 2 Set up a deep well, through the setting of the deep well, effectively lower the groundwater level and lay the foundation for the next work;
[0072] Step 3, build high-pressure saline-alkali, with an average of 100m 2 Build a high ridge, the ridge is 40-50cm high, and then inject it with a water height of 20cm, once, 10 days each time, use the dissolution and dilution of water to dissolve the saline-alkali components in the soi...
Embodiment 3
[0078] A comprehensive method for biological improvement of saline-alkali land, characterized in that the specific steps are as follows:
[0079] Step 1, deep plowing and plowing, deep plowing the saline-alkali soil twice with a tiller, the plowing depth is 30cm; loosen the soil, increase the permeability and porosity of the soil; expose to the sun, expose the soil after each deep plowing for 2 times, 15 days each time, to promote soil loosening and the precipitation of saline-alkali components;
[0080] Step 2, drilling wells, on average every 3000m 2 Set up a deep well, through the setting of the deep well, effectively lower the groundwater level and lay the foundation for the next work;
[0081] Step 3, build high-pressure saline-alkali, with an average of 110m 2 Build a high ridge, the ridge is 40-50cm high, and then inject, water 30cm high, twice, 10 days each time, use the dissolution and dilution of water to dissolve the saline-alkali components in the soil, discharge...
