Description

A kind of compound fertilizer and preparation method thereof improving soil texture
Technical field
The present invention relates to fertilizer fields, and in particular to a kind of compound fertilizer and preparation method thereof for improving soil texture.
Background technique
Chemical fertilizer plays very important effect to Agriculture Production in the history of China's existing over half a century.China It is a large agricultural country, ratio of the chemical fertilizer in productive investment in agriculture accounts for about 50%, but the utilization rate of China's fertilizer is but Only 30%, it thereby results in the huge waste on economical energy resources and has caused various environmental problems.If not applying chemical fertilizer, The grain yield of China will reduce the even more yield of one third.But with the increasingly increase that chemical fertilizer is put into, negative shadow Sound also gradually shows especially out.Currently, since agriculturally a large amount of application chemical fertilizer cause soil acidification aggravation, soil depletion and plate for a long time Knot, and there is a series of problems, such as soil environment, water environment pollution, this realizes that sustainable development forms sternness to Chinese agriculture Challenge, therefore it is extremely urgent to improve soil quality.
Soil quality is the material base of agricultural production, and soil physical properties and chemical property are the important sets of soil quality At keeping soil, suitable physical property is to improve one of the premise of agricultural production.How to improve soil texture, is crop root The emphasis of a more comfortable growing environment and agriculturist's following work is built, product of the present invention has good Water-retaining property and adequately dispersibility, effectively improve and improve the function of topsoil soils structure while protecting water storage fertilizer.
Drought and water shortage is an important factor for restricting China's agricultural development and accelerate desertification of land, to improve Farmland Water and utilize The Farmland Water utilization rate of rate especially Arid&semi-arid area becomes one of the central task of China's agricultural.Agricultural water-loss reducer tool There is drought-resistant water-preserving, heat preservation, sustained-release synergistic, improve the effects of soil texture, soil water evaporation can be inhibited, improve soil saturation Water content, reduction can leaching nutrient leaching loss, improve utilization rate of fertilizer, while can reduce the soil weight, improve soil Earth structure and water and heat condition.Water-retaining agent although water-absorbing-retaining effect with super strength, but do not have fertilizer nutrient, and nutrient is then Production estimation and the necessary nutritional condition of vegetation growth, meanwhile, water-retaining agent and fertilizer are applied time-consuming respectively, are also unfavorable for The performance of water-fertilizer interaction and liquid manure effect.
Therefore, the material of water retaining function is combined with fertilizer, preparation can delay the function that controlled release nutrients have water conservation, drought resisting again The research of energy diversification fertilizer will become fertilizer and research and produce the new hot spot in field.
The moisture-retention sustained adjustable soil moisture surplus and deficiency of release and release control fertilizer improves liquid manure interaction, improves water, fertilizer utilizes effect Rate reduces fertilizer nutrient leaching shifting, fixed or volatilization loss, mitigates environmental pollution.Therefore, by fertilizer and water-retaining agent composite integrated Change, have complementary advantages, before the moisture-retention sustained release and release control fertilizer that manufacturing, there is water retaining function and nutrient to delay control-release function becomes fertilizer research Edge and direction meet water-saving and dry farming production actual needs.
