Problems solved by technology
[0002] Large and long-term use of blended fertilizers during the growth of rice crops will reduce the stress resistance of rice, including resistance to diseases and insect pests, lodging, cold resistance, drought resistance, etc., resulting in reduced rice production and product quality; at the same time, it will also cause soil acidification and harden and reduce fertility; in addition, the enrichment of heavy metals in fertilizers will also cause food safety hazards

Abstract
The invention discloses a production method for adding humic acid and sodium silicate in a blended fertilizer, and relates to the technical field of fertilizer production. The production method comprises the following steps: granulating humic acid through a rotating drum steam granulator, and spraying a sodium silicate water solution in the granulating process; then, adding the prepared humic acid and sodium silicate granules in the batching process of the blended fertilizer; and finally, screening, mixing, metering, and packaging to obtain the finished blended fertilizer product. According to the invention, the humic acid and the sodium silicate are added in the blended fertilizer, so that required nitrogen, phosphorus, potassium and silicon element nutrients can be provided for growth of rice, the biological activity of the humic acid can be improved, and the problems of rice planting field such as soil acidification and hardening, fertility decline, heavy metal enrichment and the like can be effectively relieved; and the rice yield can be improved obviously.
Description
Technical field: [0001] The invention relates to the technical field of fertilizer production, in particular to a production method for adding humic acid and sodium silicate to a blended fertilizer. Background technique: [0002] Large and long-term use of blended fertilizers during the growth of rice crops will reduce the stress resistance of rice, including resistance to diseases and insect pests, lodging, cold resistance, drought resistance, etc., resulting in reduced rice production and product quality; at the same time, it will also cause soil acidification and In addition, the accumulation of heavy metals in fertilizers can also cause food safety hazards. Therefore, it is urgent for the healthy development of agricultural production to solve the serious problems of food safety caused by soil acidification and compaction of agricultural land, the decline of fertility, and the accumulation of heavy metals (lead Pb, mercury Hg, arsenic As, cadmium Cd, chromium Cr). [00...
