Problems solved by technology

[0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. From the perspective of soil structure, saline-alkali land is all compacted soil. The air permeability and water permeability of the soil are very poor, and the salt is mixed in In compacted soil, it is difficult to be separated, resulting in precipitation year by year, and the salt content is getting higher and higher. However, when the existing saline-alkali land is repaired, the repair is not complete, and the soil surface is often repaired; after a long time, The salt in the bottom soil will return to the surface; at the same time, in the process of land restoration in the past, crops were also planted on saline-alkali land, but after the crops were harvested, only the root system was left, but the straw of the crops did not Being well utilized will result in a waste of resources

Embodiment 1

[0015] A method for improving saline-alkali land restoration, comprising the following steps: 1) flushing: digging a 3.4m-deep ditch around the land to be repaired, inserting a layer of cement board on the ditch; connecting a polyethylene Drainage pipes; use pumps to draw water to flush the land to be repaired. The flushing cycle is 7 days and 11 consecutive flushes; 2) Deep plowing: the land to be repaired must be turned over. Gradually plow towards the center; and during the plowing process, it is necessary to manually screen out non-perishable organic matter; use a plow machine to plow the land to be restored after plowing; plow the land to be restored after plowing Rinse again; use a sprinkle of restorative after rinsing is complete.

[0016] 3) Configuration of restoration agent: 6 parts of calcium oxide, 23 parts of silicon dioxide, 7 parts of aluminum oxide, 1.5 parts of sulfur trioxide, 9 parts of iron oxide, 0.9 parts of magnesium oxide, 0.5 parts of titanium dioxide,...

Embodiment 2

[0018] A method for improving saline-alkali land restoration, comprising the following steps: 1) flushing: digging a 2.3m-deep ditch around the land to be repaired, inserting a layer of cement board on the ditch; connecting a polyethylene Drainage pipes; use pumps to draw water to flush the land to be repaired. The cycle of flushing is 4 days and 10 times in a row; Gradually plow towards the center; and during the plowing process, it is necessary to manually screen out non-perishable organic matter; use a plow machine to plow the land to be restored after plowing; plow the land to be restored after plowing Rinse again; use a sprinkle of restorative after rinsing is complete.

[0019] 3) Configuration of restoration agent: 5 parts of calcium oxide, 22 parts of silicon dioxide, 6 parts of aluminum oxide, 1.4 parts of sulfur trioxide, 8 parts of iron oxide, 0.8 parts of magnesium oxide, 0.1-0.5 parts of titanium dioxide, and 1.1 parts of potassium oxide , 0.5 parts of manganese ...

Abstract

The invention discloses a saline-alkali land restoration method by improving soil. The method includes the following steps that 1, flushing is conducted, wherein a trench with the depth of 2.3-2.4 m is dug around to-be-remedied soil, a cement plate is inserted in the trench, a water suction pump is used for pumping water to flush the to-be-remedied soil once every 4-7 days, and flushing is continuously conducted for 7-11 times; 2, the soil is ploughed repeatedly in a turning mode, and a restoration agent is spread, so that the restoration agent is mixed evenly with soil of the saline-alkali land and can enters the bottommost portion of a soil layer and saline-alkali soil in the deep of the ground can be conveniently remedied; 3, at the same time, after crops are harvested, plant ash obtained after incineration returns to the saline-alkali land again, the pH value of the saline-alkali land can be greatly improved, the properties of the land are thus improved, and replantation in the later period is facilitated.
