Soil conditioner and preparation method thereof

Abstract

The invention discloses a soil conditioner and a preparation method thereof. The soil conditioner comprises 21% of silicon fertilizer, 25% of natural peat containing humic acid, 49% of a clay mineral and 5% of bioremediating inoculant. Slow-release silicon fertilizer is adopted as the silicon fertilizer, the clay mineral is kaolin, and the bioremediating inoculant is formed by 50% of iron-reducing bacteria, 30% of bacilli and 20% of photosynthetic bacteria in a composite mode. After the raw materials are mixed according to the ratio, charging, stirring and mixing, secondary charging, room-temperature drying, smashing, secondary stirring and mixing, packaging and storing are carried out to prepare the soil conditioner. According to the soil conditioner, an agricultural water-retaining agent, the natural peat rich in organic matter and the humic acid and other organic matter are used as main raw materials, biological active components and nutrient components are auxiliary materials, and the soil conditioner is processed through a scientific technology and has three kinds of remarkable soil conditioning performance of water retaining, fertility increasing and ventilation.

Description

technical field [0001] The invention belongs to the field of soil fertilizer technology, and in particular relates to a soil conditioner and a preparation method thereof. Background technique [0002] my country is a big agricultural country, owning 10% of the world's arable land and consuming 30% of the world's chemical fertilizers. In my country's agriculture, inorganic chemical fertilizers are mostly used to increase the yield of crops. Long-term large-scale application of chemical fertilizers solves the problem of food quantity and increases economic income, but at the same time destroys the structure of the soil, causing serious soil acidification and compaction. Especially for land degraded areas, the original soil fertility base is poor, which will lead to more compacted soil, lower fertilizer utilization rate, loss of soil nutrition balance, and decreased fertility. [0003] Excessive residues of harmful substances such as chemicals, hormones, chloride radicals, and ...
