Fertilizer rich in organic potassium and preparation method thereof

Abstract

The invention discloses a fertilizer rich in organic potassium and a preparation method thereof. The fertilizer rich in organic potassium consists of the following components in parts by weight: 14-18 parts of potassium sulfate, 0.7-1.8 parts of ferrous sulfate, 6-9 parts of ammonium sulfate, 13-15 parts of diammonium phosphate, 0.7-1.8 parts of borax, 5-8 parts of bentonite, 4-7 parts of diatomite, 5-8 parts of high-calcium clay, 3-6 parts of zeolite, 4-6 parts of fulvic acid, 20-25 parts of plant straw, 4-7 parts of trace element, 1-3 parts of fenaminosulf and 2-4 parts of chlorothalonil. Since plants highly rich in potassium including celosia argentea, pokeberry root, rudbeckia laciniata, stylosanthes guianensis and amaranthus cruentus are adopted in the fertilizer, not only the active ingredients of the fertilizer but also the content of organic potassium in the fertilizer are increased.

Description

technical field [0001] The invention relates to a fertilizer rich in organic potassium and a preparation method thereof. Background technique [0002] At present, due to the increasing use of chemical fertilizers, most of the varieties used are unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and weakened water and fertilizer retention. The blind pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low, and some even cause low-quality agricultural products, endangering the health of consumers; the physical properties are not good, there is a lot of dust, they are not compressive, agglomerated, and it is not easy to store , transportation and fertilization. Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they a...
