Embodiment Construction

[0008] The invention provides a two-component saline-alkali soil improver. The preparation method is as follows: (1) Dissolve 1000g of brown sugar or 2000g of dried potato in 50Kg of boiling water and cool to 40°C; Ammonium 100g, keep moisture between 26-38°C, let it ferment until the pH value is ≤4±0.3 to prepare solution A; (2) Mix 1000g bran, 500g bean cake, and 100g bone glue and boil in 50Kg boiling water for 1 hour , cooled to 40-60°C, add 5000g of lignite or peat powder with low combustion value, and 100g of ammonium nitrate, put it in a container and react until the pH value is ≤5±0.3, filter or precipitate to obtain solution B and residue C.

[0009] The application method of the two-component saline-alkali soil improver provided by the present invention: the solution A and the solution B prepared by the above method are alternately poured into the soil, and the residue C is piled and applied on the soil surface. In actual use, solution A and solution B can be diluted...

Abstract

The invention is a kind of modifier for salt-alkaline land, which is composed by brown sugar, black leaven, white vinegar, ammonium nitrate, bran, bean cake, bone glue, bovey coal, A or B liquor and c bottom. top-dress the A or B liquor by canalization in turn, top-dress the C bottom to the surface of the land, in this way, the modifier will be good for the root of he plant. The mount of land's organics will increase and the capability of holding water of the land will also improve. The modifier will reform land's performance of physical and chemistry and activate the organic phosphorus in the land. In a word, the invention is good for plant's developing and salt-alkaline land's fathering.

Description

technical field [0001] The invention relates to a preparation and application method of a saline-alkali soil improving agent. Background technique [0002] Saline-alkali land is widely distributed in my country, with an area of ​​hundreds of millions of mu according to statistics. The characteristics of this kind of land are: there are too many soluble salts in the soil, it is highly alkaline, and its permeability and water retention are poor, which hinders the normal growth of plants, causes the deterioration of the regional ecological environment, and restricts economic development. , therefore, the development and utilization of saline-alkali land is of great significance. At present, the method of transforming saline-alkali land is generally to reduce the salinity and alkali discharge through leaching, and then combine the application of soil amendments to increase the organic matter and nutrient content in the soil. Actual tests have shown that most of the existing me...
