Embodiment 1
[0022] Embodiment 1: produce the required raw material of 100kg product and method:
[0023] 20kg of 10% sulfuric acid, 20kg of desulfurized gypsum, 5kg of seaweed polysaccharide, 5kg of humic acid, 5kg of peat, 10kg of carboxylate (sugar calcium), 20kg of green manure, and 15kg of farmyard manure can be used to obtain the soda saline-alkaline soil improver.
[0024] When in use, according to the soil pH > 9.5, apply 150-200 kg of improver per mu, and apply 50-150 kg of improver per mu if the soil pH is 8.5-9.5.
Embodiment 2
[0025] Embodiment 2: produce the required raw material of 100kg product and method:
[0026] Mix 15kg of 10% sulfuric acid, 30kg of desulfurized gypsum, 5kg of cellulose, 5kg of humic acid, 5kg of straw carbon, 15kg of carboxylate (sugar calcium), 15kg of leguminous green manure, and 10kg of farmyard manure to obtain soda saline-alkali soil Improver.
[0027] When in use, according to soil pH > 9.5, apply 200-300 kg of improver per mu, and if the soil pH is 8.5-9.5, apply 100-200 kg of improver per mu.
Embodiment 3
[0028] Embodiment 3: produce the required raw material of 100kg product and method:
[0029] 10kg of 10% sulfuric acid, 15kg of desulfurized gypsum, 10kg of vermiculite, 10kg of cellulose, 10kg of humic acid, 10kg of peat, 15kg of carboxylate (sugar calcium), 10kg of leguminous green manure, and 10kg of farmyard manure. Mix thoroughly to obtain a soda saline modifier.
[0030] When in use, according to soil pH > 9.5, apply 250-350 kg of improver per mu, and if the soil pH is 8.5-9.5, apply 150-250 kg of improver per mu.

Abstract
The invention relates to a saline-alkaline land improving agent, in particular to an inland soda saline-alkaline land improving agent and application. The improving agent is prepared from sulfuric acid, natural mineral, natural polymers, organic materials and organic solid waste. After the ingredients are sufficiently and uniformly mixed according to the proportion, the inland soda saline-alkaline land improving agent can be obtained. The inland soda saline-alkaline land improving agent is applicable to inland soda saline-alkaline land improvement; after the application to field experiments, the result shows that the soil pH value is reduced by 1.2 to 2.2; the saline content is reduced by 20 to 42 percent; the rice seedling survival rate reaches 100 percent; the yield in the high-degree saline-alkaline land is increased by 7 to 10 times. The preparation method of the soda saline-alkaline land improving agent is simple; the application cost is lower; the saline-alkaline land improving effect is obvious; the yield increase and income increase effects are achieved.
Description
technical field [0001] The invention relates to a saline-alkali improvement agent, in particular to an inland soda saline-alkali improvement agent and its application. Background technique [0002] According to the second national soil census statistics of the Ministry of Agriculture, the total area of saline-alkali soil in my country is 3466×10 4 hm 2 , of which cultivated land accounts for 16.6%. The Songnen Plain is one of the world's three largest soda saline-alkali soil distribution areas. The salinized land area is 380×10 4 hm 2 , of which the cultivated land is 127×10 4 hm 2 . The salt ions in the soda-type saline-alkali soil are mainly Na + , Ca 2+ , CO 3 2- 、HCO 3- The ground vegetation is sparse, the bioaccumulation is weak, and the soil leaching is weak, which is not conducive to the growth of vegetation. The natural vegetation communities in the area are mainly meadow grassland and desert grassland. Problems such as production reduction or even extin...
