Embodiment 1

[0043] A soil improver, with organic matrix, inorganic matrix, nutrient elements, and composite resin as basic raw materials, the mass parts of each component are: 55 parts of weathered coal, 25 parts of bentonite, 10 parts of composite resin, 3 parts of monoammonium phosphate, Potassium sulfate 7 parts.

[0044] The preparation method is as follows:

[0045] (1) Grinding the weathered coal and furfural slag to a particle diameter of 0.1-0.3 mm. 250 parts by weight of water, 30 parts by weight of furfural slag, 70 parts by weight of weathered coal, and 6 parts by weight of acrylic acid (neutralization degree 60%) were sequentially added into the reactor, and stirred evenly. Under nitrogen protection, 0.2 parts by mass of methylenebisacrylamide and 2 parts by mass of ammonium persulfate were added. After reacting at 60-70°C for 3 hours, the product is composite resin.

[0046] (2) Dry the organic matrix, inorganic matrix, nutritional elements, and composite resin until the w...

Abstract

The invention discloses a multifunctional soil conditioner applicable to a Bohai granary demonstration area. The multifunctional soil conditioner is obtained through the steps of producing a composite resin by use of furfural residue, decomposed coal and the like, and next, pelleting basic raw materials, such as an organic matrix, an inorganic matrix, nutrient elements and the composite resin, by use of a disc, wherein the nutrient elements are combined in the mass ratio of N to P2O5 to K2O being (0.3-0.7) to (1.2-2.8) to (2.0-3.6). The multifunctional soil conditioner is low in raw material cost and simpler in preparation process, has remarkable effects of water retention, fertility intensification and salt inhibition, is convenient for mechanical application, and remarkable in economic and ecologic benefits, and is an environment-friendly soil conditioner.

Description

technical field [0001] The invention relates to the field of soil improver or soil conditioner manufacture, in particular to a multifunctional soil improver suitable for Bohai granary demonstration areas (medium and low-yield fields and saline-alkali lands around the Bohai Sea) and a preparation and application method thereof. Background technique [0002] Low- and medium-yield fields are an important factor restricting the current sustained and stable increase in grain production and sustainable agricultural development, as well as an important breakthrough in increasing grain production. The Bohai Rim region is an important agricultural product production base and an area of ​​rapid economic development in my country. However, due to factors such as lack of fresh water resources, barren soil, and salinity, there are more than 40 million mu of low-yield fields and fields in the four provinces (cities) around the Bohai Sea. More than 10 million mu of saline-alkaline wasteland...
