Abstract
The invention discloses an improving agent for soil of saline and alkaline lands. The improving agent is prepared from the following components in parts by weight: 40-60 parts of phosphorus gypsum, 15-30 parts of black soil, 5-8 parts of ageratina adenophora, 3-5 parts of iris japonica thunb, 5-8 parts of pine needle, 1-2 parts of hydrochloric acid, 3-6 parts of acetic acid and 3-6 parts of oil cake. A preparation method comprises the following steps: (1) taking the phosphorus gypsum, drying, crushing and sieving to obtain phosphorus gypsum powder for later use; (2) taking the black soil, drying, crushing and sieving to obtain black soil powder for later use; (3) respectively crushing and sieving the other components and ingredients, adding the hydrochloric acid and the acetic acid and mixing, then adding 1-3 parts of raw glucoamylase and 15-20 parts of water, stirring and fermenting; (4) adding the phosphorus gypsum powder and the black soil powder into a fermented mixture, stirring and controlling the water content of the mixture to be 15%-20%. The improving agent disclosed by the invention has the beneficial effects that the problem of failure to realize utilization of large-batch phosphorus gypsum as a fertilizer ingredient in the prior art can be solved; meanwhile, prepared fertilizer has the effects of reducing the salinity and the alkalinity of the soil and improving thefertility of the soil so as to be suitable for growth of crops.
Description
technical field [0001] The invention relates to a soil conditioner for saline-alkali land and a preparation method thereof, belonging to an agricultural fertilizer in the field of agriculture. Background technique [0002] Phosphogypsum is a by-product discharged from the production process of wet-process phosphoric acid. The phosphate fertilizer and phosphorus chemical industry and other industries discharge more than 10 million tons of gypsum waste residue every year. How to develop and utilize these phosphogypsum waste residues and turn waste into treasure is the world's It is a hot topic that every country has been paying attention to for a long time. [0003] At present, the use of phosphogypsum is more commonly used as building materials, such as cement retarder, gypsum building materials, roadbed fillers, wall blocks and so on. The other is to use phosphogypsum to produce phosphate compound fertilizer, but it is mainly treated by stockpiling, which not only has a low...
