Abstract

The invention discloses compound fertilizer for improving a coastal sandy saline and alkaline land and a preparation method thereof. The compound fertilizer for improving the coastal sandy saline andalkaline land is prepared from attapulgite clay, desulphurization gypsum, organic fertilizer, fulvic acid, citric acid, a sandy soil binding agent, a compound water retaining agent, a saline and alkaline land improvement agent, expanded vermiculite and microorganism powder at the weight ratio of (24 to 30) to (8 to 12) to (20 to 22) to (12 to 16) to (6 to 8) to (5 to 7) to (5 to 7) to (4 to 6) to(2 to 4) to (0.5 to 1.5). The compound fertilizer for improving the coastal sandy saline and alkaline land can be used for effectively improving a soil structure of the sandy saline and alkaline land,reducing the saline and alkaline degree, reducing the sand content in soil, improving the content of nutrient components in the soil and improving the compacting degree of the soil; the compound fertilizer is matched with plant cultivation and the sandy saline and alkaline land can be continuously and effectively improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a compound fertilizer for improving coastal sandy saline-alkali land 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 lan...
