Sandy saline land improving fertilizer, and preparation method thereof

Abstract

The invention discloses a sandy saline land improving fertilizer, and a preparation method thereof. The sandy saline land improving fertilizer comprises a fertilizer A and a fertilizer B; the fertilizer A comprises, by weight, 25 to 35 parts of plant straw particle, 20 to 30 parts of animal manure, 14 to 16 parts of attapulgite clay, 14 to 16 parts of humic acid, 8 to 12 parts of peat, 2 to 4 parts of a saline land improving agent, and 1 to 3 parts of a microbial agent powder; the fertilizer B is a sand adhesive composed of, by weight, 35 to 45 parts of gelatin, 8 to 12 parts of water glass, 18 to 22 parts of modified aqueous polyurethane, 16 to 20 parts of gypsum, 4 to 8 parts of turpentine, and 4 to 8 parts of manganese dioxide. The sandy saline land improving fertilizer is capable of improving sandy saline land soil structure, reducing saline-alkaline degree, reducing solid sand content, increasing soil nutrient content, and improving soil compaction degree; and combination of the sandy saline land improving fertilizer with plant plantation is capable of improving sandy saline land everlastingly and effectively.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a sandy saline soil improvement fertilizer and a preparation method thereof. Background technique [0002] At present, my country's soil is one of the countries most seriously harmed by desertification and salinization in the world. Sandification and salinization have a large area and wide distribution, aggravating the deterioration of the ecological environment, and large areas of beaches and tidal flats are also constantly eroding the surrounding areas. The soil has seriously affected the development of my country's industry, agriculture and social economy, threatened the survival and development space of the nation, and caused serious economic losses; Degradation remains severe. [0003] Due to the loose sandy soil particles, strong fluidity and weak interaction between particles, it is easy to damage land resources and land productivity under the action of...

[0002] At present, my country's soil is one of the countries most seriously harmed by desertification and salinization in the world. Sandification and salinization have a large area and wide distribution, aggravating the deterioration of the ecological environment, and large areas of beaches and tidal flats are also constantly eroding the surrounding areas. The soil has seriously affected the development of my country's industry, agriculture and social economy, threatened the survival and development space of the nation, and caused serious economic losses; Degradation is still serious

[0003] Due to loose sandy soil particles, strong fluidity, and weak interaction between particles, it is easy to damage land resources and land productivity under the action of external forces such as water, gravity, and wind, resulting in land surface erosion and water loss.

In addition, the degree of salinization is getting heavier and the soil nutrients are poor, which greatly restricts the productivity level of planting and the recovery ability of vegetation in sandy soil areas.
