Fertilizer for rapidly improving sandy soil and preparation method thereof

Abstract

A disclosed fertilizer for rapidly improving sandy soil comprises 2-4 parts of a rapid-release organic fertilizer(chicken manure, duck manure, pig manure, bean cakes and the like), 2-4 parts of a sustained-release organic fertilizer(crop straws, cow dung and the like), and 3-5 parts of a water-retaining fertilizer (turf or coconut shell powder). The fertilizer is capable of rapidly improving the fertilizer-retaining water-retaining capability of sandy soil and improving crop yield. A preparation method of the fertilizer comprises: airing 2-4 parts of the rapid-release organic fertilizer to a half-dry state, crushing 2-4 parts of the sustained-release organic fertilizer, mixing the rapid-release organic fertilizer with the sustained-release organic fertilizer, adding water to have the humidity of 60-70%, adding an EM microbial bacterial fertilizer according to a standard of 0.5-1 Kg of the microbial bacterial fertilizer for 1 cubic meter of the mixture, piling up fermentation piles and fermenting for 10-50 days, adding water into the water-retaining fertilizer to have the humidity of 80-90%, and uniformly mixing with the fermented fertilizer, so as to obtained the final fertilizer.

Description

technical field

[0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a fertilizer for rapidly improving sandy soil and a preparation method thereof, belonging to the field of fertilizer production. Background technique

[0002] Soil is generally divided into sandy soil, clay soil and loam according to texture. Sandy soil has a lot of sand content, rough particles, fast water seepage, and poor water retention performance. It is mainly distributed in the piedmont plains of Xinjiang, Gansu, Ningxia, Inner Mongolia, and Qinghai, as well as the banks of rivers and coastal plains in various places in Northwest my country.

[0003] The biological role of the sandy soil in the formation process is very weak, while the thin layer of weathering crust is affected by the dry and hot climate and becomes the dominant role in the soil formation process. The surface is mostly sandy. Sandy soil is characterized by large soil particles, low organic ...
