Abstract

The invention belongs to the field of crop fertilizers, and particularly relates to a green ecological potash fertilizer and a preparation method thereof. The green ecological potash fertilizer is mainly prepared from a potash fertilizer, water hyacinth, phosphate ore and an active conditioner, and prepared by the following steps: firstly removing heavy metals from the water hyacinth, and then mixing the processed water hyacinth with the potash fertilizer and the active conditioner. According to the green ecological potash fertilizer, the water hyacinth is used as a main organic matter, so that the leaching loss of the potash fertilizer in the soil can be avoided, meanwhile, the soil is improved, soil hardening is reduced, the organic matter in the soil is increased, the microbial activity is improved, and the stress resistance and the disease resistance of the crops are improved; while the potash fertilizer is provided, the water hyacinth which has a certain negative effect on the environment is reasonably utilized, so that the environment burden can be reduced; the green ecological potash fertilizer is an environment-friendly ecological fertilizer which is safe and non-toxic to people and livestock, and environment-friendly.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and more precisely relates to a green and environment-friendly ecological potash fertilizer and a preparation method thereof. Background technique [0002] Ecological fertilizer is an environmentally friendly fertilizer, which contains a large amount of organic matter. Applying it to the soil can promote the activity of microorganisms in the soil, enhance the ability of crops to resist stress and disease, reduce crop repeated cropping, and apply it year after year. It can greatly alleviate the obstacles of continuous cropping and improve agricultural products. quality; it can also improve the soil structure, increase the porosity of the soil, and prevent soil compaction; at the same time, it can reduce water loss and evaporation, reduce the pressure of drought, preserve fertilizer, reduce chemical fertilizers, reduce saline-alkali damage, improve soil fertility, and achieve the goal of providing n...
