Soil conditioner and fertilizer comprising same

Abstract

The invention discloses a soil conditioner and a fertilizer comprising the same. The soil conditioner consists of the following components in percentages by mass: 20-50% of mineral resource potassiumfulvic acid, 20-30% of alginic acid or alginate, 10-30% of medium trace element chelate and 10-30% of bentonite. According to the soil conditioner, soil granular structures are increased by high-activity short carbon-chain micromolecule structures of active mineral resource potassium fulvic acid; and meanwhile, by the alkalinity of the soil conditioner, acid soil and saline-alkali soil can be subjected to acid-alkali buffering and conditioning, and nutrients in soil are activated. The soil conditioner is further added with the alginic acid and the bentonite, the water retention effect of the soil is improved, the soil granular structures can be increased further, substitution capacity of the soil is increased, and therefore, the soil buffering effect is improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner and a fertilizer containing the soil conditioner. Background technique [0002] The normal growth and development of food and commercial crops depends on a good soil environment. The neutral soil environment is most conducive to the growth of most plants, and the overacid and overalkaline environment is not conducive to the normal growth of most plants. In the early decades of agricultural planting in China, the increase in food production mainly relied on the application of a large amount of chemical fertilizers. Excessive fertilization for a long time caused soil compaction, a decline in organic matter, a decrease in beneficial microorganisms, and soil acidification. In acidic soil, iron and aluminum oxides are obviously enriched, the cycle of biomass is very rapid, and the soil base saturation is low; and it is easy to suffer from strong leaching, a...

Problems solved by technology

At present, the conditioners used based on the above-mentioned active mechanism are easy to lose after application, and due to the huge amount of soil in the field, after the conditioner is applied, there can only be an overall change in the macroscopic surface of the soil, and it cannot effectively make the changed The effect reaches the micro-environmental level of the crop root system, which increases the cost of fertilizers and prolongs the production cycle of conditioners during implementation
