Bio-organic compound fertilizer and its manufacturing method used to treat secondary saline-alkali land and produced by food waste

Abstract

This invention discloses a kind of bio-organic compound fertilizer used to treat secondary saline-alkali land and produced with food waste, which include the following components in different proportions: 150-200 parts of food waste, 5-20 parts of soil conditioner, 30-40 parts of salt releasing agent, 16-25 parts of compound microbial agent, 20-40 parts of phosphate solubilizing bacteria, 10-20 parts of cyanophytes, 10-15 parts of meerschaum, 10-15 parts of aluminium sulfate, 10-20 parts of polyacrylamide, the soil conditioner above mentioned is constituted by the following component in different proportions: 20-30 parts of carbamide , 20-30 parts of natriumboricum, 20-30 parts of monoammonium phosphate, 5-10 parts of manganese sulfate, 16-20 parts of zine sulfate,4-10 parts of monosodium glutamate, and 12-16 parts of borax. This invention provides bio-organic compound fertilizer used to treat secondary saline-alkali land and produced with food waste. The raw material iseasily got, the manufacturing is simple, and the compound fertilizer has multi-function, and can increase the fertility of saline-alkali land, at the same time, can loosen the soil and retain the moisture.

Description

technical field [0001] The invention relates to a bio-organic compound fertilizer produced from food waste and used for treating secondary saline-alkali land and a manufacturing method thereof. Background technique [0002] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land into "salinization" due to unreasonable cultivation and irrigation measures and changes in vegetation. It mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, Weihe Plain and other places. There are three main reasons for the formation of secondary salinization: First, the drainage system of farmland is not smooth, and a large amount of water diversion irrigation has raised the groundwater level, increased the speed of groundwater moving upward through the soil capillary and the evaporation of groundwater, thereby increasing the groundwater and the lower level. The salt in the soil accumulates to the surface....
