Embodiment Construction

[0009] The present invention provides a two-component saline-alkali improving agent, and its preparation method is as follows: (1) After dissolving 1000g of brown sugar or 2000g of dried potato in 50Kg of boiling water, it is cooled to 40°C; then 20g of black rice, 50g of white vinegar, and nitric acid are added. 100g of ammonium, keep it between 26-38℃, and let it ferment to pH ≤4±0.3 to prepare solution A; (2) Mix 1000g of bran, 500g of bean cake, and 100g of bone glue and boil in 50Kg of boiling water for 1 hour , Cool to 40-60℃, add 5000g lignite or peat powder with lower burning value, and add 100g ammonium nitrate, put in a container to react until the PH value is ≤5±0.3, filter or precipitate to obtain solution B and residue C.

[0010] The application method of the two-component saline-alkali soil conditioner provided by the present invention: the solution A and the solution B prepared by the above method are alternately irrigated into the soil, and the residue C is piled ...

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 improver. Background technique [0002] Saline-alkali land is widely distributed in my country, and according to statistics, its area reaches hundreds of millions of mu. The characteristics of this kind of land are: excessive soluble salts in the soil, high alkalinity, poor permeability and water retention, hindering the normal growth of plants, causing the deterioration of the regional ecological environment, and restricting economic development Therefore, the development and utilization of saline-alkali land is of great significance. At present, the method of transforming saline-alkali soil is generally to reduce the salt content and discharge alkali through leaching, combined with the application of soil amendments to increase the organic matter and nutrients in the soil. Practical tests have shown that most of the existing methods can only act on the surface of the soi...
