Carbon-based organic and inorganic compound fertilizer, as well as production process and fertilizing method thereof

Abstract

The invention relates to agricultural fertilizer, and particularly relates to carbon-based inorganic fertilizer, as well as a production process and fertilizing method thereof. The fertilizer is prepared from the following components in parts by weight: 20-40 parts of husks, 12-17 parts of ammonium phosphate, 20-25 parts of urea, 12-20 parts of lignite powder, 5-10 parts of boric acid, 15-25 partsof potassium chloride, 5-10 parts of zinc sulfate, 5-15 parts of bentonite and 5-15 parts of livestock and poultry excrement. According to the inorganic fertilizer, coked husks are adopted as the substrate, heavy metals in soil can be adsorbed and passivated by rich pores of the coked husks, the content of heavy metals in crops can be reduced, and crops with standard safety can be provided.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a carbon-based inorganic fertilizer and its production process and fertilization method. Background technique [0002] At present, the global ecology is seriously out of balance, especially the agricultural ecology. Industrial sewage discharge pollutes fertile land, waste gas discharge causes fertile land to be acidified by acid rain, soil pH value drops, and free heavy metals in the soil increase. In order to increase production and increase, the use of various agricultural inputs has greatly increased, such as the use of chemical fertilizers. The bigger it is, the less attention is paid to the separation of heavy metals such as chromium, mercury, and zinc associated in the production process of chemical fertilizers, resulting in the effective utilization rate of chemical fertilizers becoming smaller and smaller, fertile fields are seriously polluted by chemical fertilizers, soil st...
