Dry land microelement water-retaining fertilizer and preparation method thereof

Abstract

The invention discloses dry land microelement water-retaining fertilizer and a preparation method thereof. The dry land microelement water-retaining fertilizer is prepared from, by weight, natural zeolite, dilute HCl of 2 mol / L, NaCl liquor of 6 wt%, ammonium molybdate, manganese oxide, calcium magnesium phosphate, microelements, kiselgel a, micalex particles, kaolin, humic acid, carbonization fruit shells, activated carbon and an appropriate amount of water. The kiselgel a, the mountain flour carbonization fruit shells and the like are added for improving the soil texture, the concave-convex surface layer of mountain flour particles has the function of reserving water, so that water flow permeation is slowed down, and soil hardening is prevented. The microelements are adsorbed by special zeolite particles, and thus cannot run away easily, and the microelements are effective for a long time.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a dry land trace element water-retaining fertilizer and a preparation method thereof. Background technique [0002] Because zeolite has a porous structure and has a great affinity for water, it can absorb water and gas components, increase water content in the soil, improve drought tolerance, increase gas diffusion, and promote soil respiration. Some soils that are too sandy or too sticky are not conducive to water and fertilizer retention and cultivation; after being improved by adding zeolite, the sandy soil will not leak water and fertilizer, and the clay soil can also change its three-phase ratio, so that It shows good farming performance. Therefore, the application of zeolite into the soil has played a significant role in improving the permeability of the soil. Poor infiltration leads to excessive reduction, both of which are detrimental to crop growth. [...

[0003] Agriculture and planting have now become an important indicator of a country's productivity. In order to improve production efficiency, large-scale agriculture and planting have accelerated production, which often results in the lack of nutrients in the planting land. It is inevitable to abuse chemical fertilizers to increase production. A large amount of fertilizers Using it can indeed increase the yield, but the fertilizer cannot be fully utilized within the time of planting. According to data, more than 30% of the fertilizer components are washed into the soil and rivers by rain, causing serious pollution.
