Abstract

The invention discloses a compound fertilizer for improving sandy saline-alkali soil and a preparation method thereof. The compound fertilizer for improving sandy saline-alkali soil is prepared from the following components of desulfurized gypsum, fly ash, sludge of sewage plant, peat, organic fertilizer, sand adhesive, a composite water retention agent, an improvement agent of the saline-alkali soil, and a microorganism powder according to a weight ratio of (22 to 30):(8 to 12):(14 to 16):(12 to 16):(18 to 22):(6 to 8):(3 to 5):(2 to 4):(0.5 to 1.5). The compound fertilizer for improving thesandy saline-alkali soil has the advantages that the soil structure of the sandy saline-alkali soil can be effectively improved, the saline-alkali degree is reduced, the content of sand in soil is reduced, the content of nutritional components in soil is increased, and the soil density is increased; the compound fertilizer is matched with plant cultivation, so as to lastingly and effectively improve the sandy saline-alkali soil.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a compound fertilizer for improving sandy saline-alkali land and a preparation method thereof. Background technique [0002] 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 external forces such as water, gravity, and wind, resulting in erosion of the land surface 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. Therefore, improving the aggregate structure of sandy soil, increasing the content of water-stable aggregates in sandy soil, increasing soil fertility, and reducing salinity have become the focus of research on improving sandy saline-alkali land. ...
