Embodiment 1
[0048] A method for planting corn in saline-alkali land, specifically comprising the following steps:
[0049] Step 1, deep plowing: deep plowing the saline-alkali land soil in the planting area with a plowing depth of 50 cm to obtain soft soil.
[0050] Step 2, irrigation: pour water into the soft soil, use running water to wash the original salt in the soil, and wash twice with water to obtain mild saline-alkali soil.
[0051] Step 3, open ditches: the depth of the ditches is 25cm, the width is 35cm, and the distance between adjacent ditches is 15cm.
[0052] Step 4, covering and burying organic base fertilizer and inorganic base fertilizer: apply organic base fertilizer and inorganic base fertilizer to the bottom of the ditch, and cover with soil, keep the soil surface of the planting area flat after soil covering, ferment for 8 days, and obtain organic fertilizer soil; the organic base fertilizer It is composed of biogas slurry, crop stalks, methyl cellulose and mixed acc...
