Problems solved by technology

The surface is mostly sandy. Sandy soil is characterized by large soil particles, low organic matter content, large gaps between soil particles, and poor water absorption capacity of soil particles, resulting in low fertility and infertility of sandy soil

Example Embodiment

[0017] Example one:

[0018] The time is spring, the average temperature is 10℃, and the soil test is carried out before planting. Except for the high phosphorus, the others are far below the scientific standard, so 100 kg of 18-9-18 compound fertilizer and 100 kg of superphosphate are used per mu of land. . On this basis, planting experiments were carried out in sample fields and control fields.

[0019] Due to the low nutrient element content of the soil and the slightly higher water retention capacity compared to other sandy soils, the fertilizer formula of the sample field was formulated with chicken manure, straw and chaff 4:2:3.

[0020] 1. Take 4 squares of chicken manure and sun it to semi-dry, and crush 2 squares of straw

[0021] 2. Mix the dried chicken manure and crushed straw, and add water to make the humidity reach 60-70%;

[0022] 3. Add 2 kg of EM microbial fertilizer to ferment for 30 days;

[0023] 4. Take 3 cubes of coconut bran, add water to make the humidity reach...

Example Embodiment

[0026] Embodiment two:

[0027] The time is summer, and the average temperature is 25℃. Soil testing is carried out before planting. Because soil nutrients are slightly higher than other sandy soils, but the evaporation is large in summer, the fertilizer formula is based on chicken manure, straw and bran 2:3: 5 Preparation.

[0028] 1. Take 2 cubic meters of chicken manure and sun it to semi-dry, and crush 3 cubic meters of straw;

[0029] 2. Mix the dried chicken manure and crushed straw, and add water to make the humidity reach 60-70%;

[0030] 3. Add 2 kg of EM microbial fertilizer and ferment for 10 days;

[0031] 4. Take 5 cubes of coconut bran, add water to make the humidity reach 80-90%, and mix it with the fermented fertilizer.

[0032] The planting crop was corn, the sample used the fertilizer of the present invention of 5 cubic meters, and the organic fertilizer of 5 cubic meters was used for the control.

[0033] The concentrations of various nutrient elements were tested afte...

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 ...
