Problems solved by technology

[0003] The saline-alkali land has small porosity, the soil is easy to compact, the air permeability and water permeability become poor, the activity of microorganisms and the transformation of organic matter in the soil are poor, and the soil fertility is poor
In the prior art, gypsum, phosphogypsum, etc. are applied to alkalized soil to exchange calcium ions for sodium ions on the surface of the soil colloid to improve the properties of saline-alkali land, such as ZL201310080579.2, which uses industrial solid waste to prepare soil health agents, but The effect of this soil health agent on improving saline-alkali land is slow, and the increase in yield is not obvious

preparation example Construction

[0035] 1) Sludge preparation: dig the sludge from the depths of the pond, spread the sludge and dry it in the sun. Since the soil is relatively loose, if there are agglomerates, you can use your feet to crush the agglomerates, or use a shovel to break them, and finally use The roller compactor will finely pulverize all the sludge multiple times, and the pulverized sludge will pass through an 80-mesh sieve, repeat the above process many times, and finally prepare all the sludge into 80-mesh sludge powder. appear black;

[0036] 2) Preparation of sawdust: Take the waste sawdust from the wood processing factory, measure the moisture content in the sawdust with a special moisture meter, and the sawdust with a moisture content of 60-65% is qualified and usable, and the rough detection method is general Just grab a handful of fingers and keep the water out; mix the collected sawdust with the biological fermentation agent at room temperature, put it in a tiled container, cover it wit...

Abstract

The invention relates to the field of soil health-care agents, in particular to a saline-alkali soil health-care agent and a preparation method thereof. The soil health-care agent is prepared from, by weight, 10-15 parts of leguminous green manure, 3-5 parts of sludge, 20-30 parts of saw dust, 5-15 parts of seafood powder, 20-30 parts of flyash and 3-5 parts of citric acid powder. According to the soil health-care agent, the components in use are waste basically, waste is turned into wealth, and reasonable utilization of resources is facilitated; secondly, the situation that calcium ions for alkali-affected soil come from traditional gypsum, phosphogypsum and the like is abandoned for the soil health-care agent, calcium ions can be obtained by means of seafood powder and citric acid powder under the action of water in soil, calcium ions are used for swapping out sodium ions on the surface of soil colloid, and therefore the physical and chemical properties of soil are guaranteed in a health-care mode, soil nutrients are increased, and soil alkalinity is reduced.

Description

technical field [0001] The invention relates to the field of soil health-care agents, in particular to a saline-alkali soil health-care agent and a preparation method thereof. Background technique [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. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical directions on the gr...
