Abstract

The invention discloses a soil improvement agent. The soil improvement agent is prepared from the following raw materials in parts by weight: 10-20 parts of bentonite, 5-8 parts of zeolite powder, 13-18 parts of plant straws, 15-25 parts of bean pulp, 8-13 parts of waste tobacco leaf dottle, 10-20 parts of polyacrylamide, 2-3 parts of boric acid, 10-18 parts of humic acid, 4-7 parts of chitosan, 2-3 parts of potassium sulfate and 3-4 parts of a mixed strain. A preparation process of the soil improvement agent is simple, the raw materials are sufficient, and the soil improvement agent is low in cost, has a good improvement effect and is used for preventing and controlling soil acidification and salination, so that the problem that the sustainable utilization of soil is influenced by quality reduction of soil is solved.

Description

technical field [0001] The invention belongs to the technical field of soil improver, and in particular relates to a soil improver and a preparation method thereof. Background technique [0002] At present, applying lime is a more effective and commonly used method to improve acidic soil and eliminate aluminum toxicity, but applying lime in large quantities or for a long time will not only cause soil compaction, but also the addition of a large amount of calcium will cause antagonism to magnesium and potassium, resulting in The imbalance of the three elements of soil calcium, potassium and magnesium leads to yield reduction. Excessive application of lime in acidic soil may also cause co-precipitation of magnesium and aluminum hydrated oxides, reducing the activity and phytoavailability of Mg2+ in the soil solution. In addition, there are also a lot of reports on the application of industrial waste and minerals in acidic soil improvement, such as alkali slag, fly ash, dolomi...
