Soil conditioner for agricultural planting

Abstract

The invention discloses a soil conditioner for agricultural planting. The conditioner is composed of, by weight, 15-25% of clay, 20-29% of humic acid, 6% of a water-retaining agent, 40-50% of ammonium bicarbonate and 5% of other ingredients. The other ingredients are amicronutrients fertilizer and moisture. According to the invention, problems such as low fertility, poor physical and chemical properties and the like of soil for backfill of raw-soil farmlands after new terraced fields, mining and different types of construction in the north can be solved. The soil conditioner has effects of improvement of soil fertility, conditioning of soil physical and chemical properties and quick curing. By the use of the soil conditioner, soil fertility is remarkably enhanced, soil bulk density is reduced, soil porosity is raised, soil aggregated structure is improved, water retaining capacity of soil is improved, north alkaline soil cation exchange capacity is raised, utilization rate of fertilizer is increased, and yield of field-crops on raw soil is boosted by 20-40%.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a soil conditioner for agricultural planting. Background technique [0002] The research on soil improvers and conditioners began at the end of the 19th century. During this period, natural organic matter was used as raw materials to extract natural polymers, such as cellulose, hemicellulose, lignin, polysaccharides, and humic acids. The substance is used as a soil improver, but because the natural soil improver is easily decomposed by soil microorganisms, the application period is short, and the dosage is large, a large amount of cations released after application are toxic to the soil, and it is difficult to be widely used in agricultural production, so artificially synthesized Research on modifiers has been gradually carried out. The United States first developed a synthetic polymer soil conditioner with the trade name Krilium, and then a large number of artificial synthe...

Problems solved by technology

With the deepening of research, soil improvers with specific effects have gradually become another focus of research. According to soil characteristics and their main limiting factors, people have developed improvers with specific effects, such as acidic soil improvers, alkaline soil However, there are not many or even no multi-functional soil amendments specifically for the rapid maturation and fertilization of raw soil generated by new terraced fields, mining backfill, and road construction in the hilly and gully areas of the Loess Plateau.

[0003] Therefore, in view of the characteristics of poor soil fertility, poor soil aggregate structure, and poor water and fertilizer retention capacity in northern raw soil farmland, it is necessary to develop a comprehensive and balanced multi-purpose soil improver or conditioner to effectively promote and improve soil quality. The smooth advancement of work in low-yield fields such as raw soil farmland in the north
