Technical Field
The invention relates to the field of fertilizers, in particular to a humic acid type organic-inorganic pesticide-fertilizer composition prepared from wastes of sugar mills and alcohol plants.
Background
The waste alcohol liquid from sugar refinery is an acidic waste liquid left after preparing alcohol from residual molasses from sugar refinery such as cane sugar factory, beet sugar factory, etc. the waste liquid contains a large amount of organic matter and beneficial elements. Millions of tons of waste liquid are discharged every year in China at present, and the problem of serious environmental pollution is caused. At present, the main utilization mode of the waste liquid is direct irrigation, and on one hand, the extensive application mode is not beneficial to the effective utilization of nutrition; on the other hand, due to the limitation of transportation and the like, the application mode is limited to the periphery of a factory; in addition, the waste liquid discharged directly is acidic, and soil hardening can be caused after long-term use.
The long-term use of inorganic fertilizer can cause soil hardening, the utilization rate of the fertilizer is reduced, and underground water is polluted.
Document CN1480430A discloses a liquid fertilizer made from molasses alcohol waste liquor and a preparation method thereof.
Patent document CN101632357A discloses a cotton pot seedling raising, root increasing and seedling strengthening composition, which comprises triazolone as a bactericide, and indoleacetic acid and paclobutrazol as growth regulators. This document controls the growth of seedlings mainly by the action of growth regulators or combinations thereof.
At present, no report is found on promoting the yield increase and rooting of crops, particularly corns, by adding other organic fertilizers, inorganic fertilizers, trace element fertilizers, tea saponin, other pesticides and the like after specially treating the alcohol waste liquid of a sugar refinery. The inventor finds that the active humic acid prepared by specially treating alcohol waste liquor of a sugar refinery is matched with the components, so that the crop yield can be remarkably increased, the crop rooting can be promoted, and the crop root-stem ratio can be increased. The present inventors have completed the present invention based on the above findings.
