Embodiment Construction

[0019] A modified magnesia pesticide residue adsorption fertilizer is prepared by the following method:

[0020] (1) Mix crop straw, poultry and livestock manure, and weathered coal at a mass ratio of 40:15:4 to ferment for 3 weeks. During this period, keep the water content of the fermented heap at 55%. After the fermentation is completed, press and filter the fermented material to obtain fermented residue and For fermented liquid, add 0.5% of the total mass of polyaspartic acid and 1.2% of chitosan to the fermented liquid, stir well and heat to 45°C, stir for 7 minutes to obtain a nutrient solution for later use;

[0021] (2) Put the magnesia into a high-temperature furnace, bake it at 500°C for 60 minutes, take it out after cooling, crush it through a 30-mesh sieve, put it into clean water and boil it for 30 minutes, cool to room temperature and filter to remove floating ash and impurities in the water , and then placed in a drying oven to dry for 10 hours, the dried powder...

Abstract

The invention discloses a modified magnesia pesticide residue adsorption fertilizer and a preparation method thereof. The modified magnesia pesticide residue adsorption fertilizer is prepared from rawmaterials such as crop processing residues, animal dung, weathered coal, monopotassium phosphate, ammonium molybdate, magnesia, tetraethyl orthosilicate and ferroferric oxide powder. The fertilizer disclosed by the invention meets the requirement of absorption of crops to various nutrients in a way of mixing organic components with inorganic components and is comprehensive in nutrients and high in utilization ratio; meanwhile, modified magnesia powder is added into a kernel of the fertilizer, nutrient components are gradually permeated into a soil layer along with the decomposition of the components after the fertilizer is applied to the soil, and the left granular components adsorb heavy metals and nuclide residues in the soil and underground water, so that the safety guarantee is provided for a soil environment of crop roots, and the soil environment suitable for the growth of crops is created; and meanwhile, the preparation method disclosed by the invention is simple and has high economic and environmental benefits and popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a modified magnesia pesticide residue adsorption fertilizer and a preparation method thereof. Background technique [0002] my country is not only a big agricultural country, but also the largest fertilizer importer, fertilizer producer and fertilizer user in the world. Fertilizer occupies a pivotal position in my country's agricultural production. At the same time, new types of intensive planting models of agricultural management entities such as family farms, professional large households, and operating cooperatives have begun to appear. After my country's agriculture realizes large-scale and intensive production, it will inevitably move towards functionalization. With the development, the demand for new fertilizers, especially functional fertilizers, will continue to increase from new business entities and business models. [0003] Traditional fertilizers are aimed at the ...
