Problems solved by technology

Among them, the production process of the liquid soil conditioner is relatively complicated, the cost is high, the use is also relatively troublesome, and the aftereffect is short.
The composition of inorganic solid soil conditioner is relatively single, the effect is poor, and most of them are used to improve alkaline soil, but the effect of improving and repairing saline soil mainly containing salt is poor

Abstract

The invention discloses a saline-alkali soil improvement and repairing agent. The saline-alkali soil improvement and repairing agent is prepared from the following components in parts by mass: 120 to 180 parts of desulfurized gypsum, 250 to 400 parts of citric acid residue, 160 to 200 parts of diatomite, 120 to 160 parts of lobster shell, 80 to 120 parts of bamboo leaf extract, 30 to 60 parts of seaweed residue, 8 to 20 parts of fly ash, 800 to 1200 parts of vinegar dreg and 10 to 14 parts of microelement fertilizer. According to the saline-alkali soil improvement and repairing agent provided by the invention, all nutrient components are reasonably matched and all the components are mutually combined, mutually influenced and mutually coordinated; soil secondary salinization caused by excessive application of chemical fertilizer can be avoided.

Description

technical field [0001] The invention relates to a soil improver, in particular to a saline-alkali soil improvement and restoration agent. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. In actual conditions, saline soil and alkaline soil often coexist in a mixed manner, collectively referred to as saline-alkali soil. [0003] At present, one of the chemical methods used to control saline-alkali land is to apply amendments to the soil. There are many kinds of existing soil conditioners, which are mainly d...
