Abstract

The invention discloses preparation and application of a potassium silicate control loss type compound fertilizer. The compound fertilizer is prepared from the following raw materials in percentage byweight: 20.0-80.0% of potassium silicate and the balance an organic and inorganic compound fertilizer body and an auxiliary agent. The fertilizer is suitable for acidic soil and can form a special colloid structure with soil particles in the acidic soil, so that the nutrient loss of the fertilizer is prevented, nutrients are fixed around a crop root system, crops absorb the nutrients according toneeds, and therefore the nutrient supply capacity of the crops is greatly improved, the healthy and rapid growth of the crops is guaranteed, the utilization rate of the fertilizer is improved, the utilization rate of the nutrients reaches up to 85.0% and is far higher than the utilization rate of a conventional fertilizer of 35.0%.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to the preparation and application of a loss-controlling potassium silicate compound fertilizer. Background technique [0002] The soil in most parts of southern my country is mainly bauxite-rich soil, such as brick red soil, red soil, red soil, and yellow soil. There are a lot of aluminum ions in the bauxite-rich soil, and the chemical properties of bauxite-rich soil are acidic. Alumina-rich soil is under tropical and subtropical humid climate conditions, the aluminosilicate minerals in the soil are strongly decomposed, and the base is continuously leached, resulting in acidic soil in the south. Acidified soil has poor structure, low fertility and high content of toxic heavy metals, which seriously affects the healthy growth of crops and threatens food security and sustainable agricultural development. According to research, silicon element plays an important role in the growth...
