Problems solved by technology

[0002] Saline-alkali soil contains a large amount of carbonate. The formation factors of saline-alkali land include climatic conditions, geographical conditions, farming management, etc. The formation of saline-alkali land will affect the normal growth of crops. When the soil salinization is serious, plants will not be able to survive.
[0003] Corn is one of the main cultivated plants in my country. Generally, the yield of corn per mu can reach more than 500 kg, but the yield of corn planted in most saline-alkali soils is less than 400 kg, which greatly reduces the land utilization rate.
In the process of traditional corn planting, chemical fertilizers are usually used. Although chemical fertilizers have quick results, due to the poor water and fertilizer retention capacity of saline-alkali land, the fertilizer effect time of chemical fertilizers is reduced and the utilization rate of fertilizers is reduced.

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...

Abstract

The invention discloses a method for planting corn in saline-alkaline soil, comprising the steps of deeply turning over, irrigating for washing, making ditches, covering with organic base fertilizer and inorganic base fertilizer, shallowly turning cover, making drain ditches, sowing corn, irrigating for washing once a month in the growth stage of corn, and applying a nutrient solution after each irrigation for washing until the corn is mature, wherein the organic base fertilizer is made by mixing biogas slurry, crop stalks, methyl cellulose and soap powder at a mass ratio of (300-500):(1000-2000):(0.5-1):(0.5-1), and the nutrient solution is made by mixing biogas slurry and crop stalks at a mass ratio of (1000-2000):(300-500), fermenting at 30-35 DEG C for 10-15 days, and filtering to obtain filtrate. By increasing the amount of organic fertilizer to be applied herein, the amount of the inorganic fertilizer to be applied is decreased; suitable soil improving measures are taken, less salt is accumulated during corn planting, and yield of corn per mu is increased. In addition, both the organic fertilizer and nutrient solution used herein are prepared mainly from stalks, returning stalks to field is achieved, and utilization rate of stalks can be increased.
