Problems solved by technology

[0004] The type and content of probiotics have different effects on different crop varieties and crop growth stages. The currently disclosed methods of combining biochar and soil probiotics include direct spraying into biochar materials (see patent No. 201510111933.2), soaking culture (see patent No. 201710820778.0), etc., which have defects such as poor carbon-bacteria binding effect and complicated operation. Microbial bacteria solidification method, and then play a comprehensive role in significantly promoting crop yield, while improving soil structure and fertilization

Abstract

The invention relates to a long-acting soil-improving compound fertilizer and a preparation method thereof. The long-acting soil-improving compound fertilizer comprises the following raw-material ingredients in parts by weight: 40-60 parts of organic-inorganic composite carbon materials, 20-30 parts of livestock and poultry manure carbide, 0.05-0.1 part of a microbial agent, 5-10 parts of fermented soybean meal, 3-8 parts of fungus dregs, and 10-15 parts of a binding agent. The preparation method of the long-acting soil-improving compound fertilizer comprises the following steps: preparing theorganic-inorganic composite carbon materials and the livestock and poultry manure carbide; and solidifying microorganisms so as to prepare the compound fertilizer. The biochar in the long-acting soil-improving compound fertilizer prepared by the preparation technology and the specific microorganism solidification method has obvious ecological benefits in promoting crop yield increase, improving soil structure and fertilizing soil fertility; moreover, probiotics adopted for the long-acting soil-improving compound fertilize are capable of improving soil structure, enhancing soil fertility and promoting yield increase. The long-acting soil-improving compound fertilizer is ecological, safe and environmentally friendly.

Description

technical field [0001] The invention relates to fertilizers, in particular to a long-acting soil improving compound fertilizer and a preparation method thereof. Background technique [0002] my country uses 9% of the world's arable land to feed 22% of the world's population, and its total grain output has exceeded 1 trillion catties for many years in a row. But behind the successive years of high yields is the high-intensity and overloaded "only plowing but not raising" predatory production and management mode, which makes the cultivated land not available for leisure for a long time. In particular, while one-sidedly pursuing high yield, the long-term and huge amount of chemical fertilizer input has seriously overloaded the soil, resulting in acidification and compaction of the soil, a reduction in organic matter, and a decrease in nutrient utilization efficiency. The lost fertilizer has caused serious non-point source pollution. Soil sustainable productivity is significant...
