Embodiment 1

[0025] This embodiment provides a kind of fertilizer with anti-drought soil loosening function, and described fertilizer comprises urea, powdery ammonium phosphate, powdery potassium fertilizer, humic acid raw material, water retaining agent, soil loosening agent bentonite, and the raw material of described composition is according to Made in the following percentages by weight: urea 20%-25%, powdered ammonium phosphate 15%-18%, powdery potassium fertilizer 18%-22%, humic acid raw material 10%-15%, water retaining agent 8%-15% , 5%-12% loosening agent and 9%-18% bentonite.

[0026] The above-mentioned humic acid raw material is an organic mixture, which belongs to short-term non-renewable resources, and is mainly divided into three categories, namely soil humic acid, water body humic acid and coal humic acid. Humic acid components mainly include fulvic acid, brown humic acid and black humic acid, which are widely distributed in nature. It mainly exists in soil, lakes, rivers,...

Embodiment 2

[0039] Take the following weights of ingredients:

[0040] Urea 22%-24%, powdered ammonium phosphate 16%-17%, powdery potassium fertilizer 19%-21%, humic acid raw material 11%-15%, water retaining agent 10%-15%, soil loosening agent 8%-11 % and bentonite 12%-16%.

[0041] The preparation steps of this embodiment are the same as those of the first embodiment, and will not be described in detail here.

Embodiment 3

[0043] Take the following weights of ingredients:

[0044] 23% urea, 16%-17% powdered ammonium phosphate, 20% powdered potassium fertilizer, 13% humic acid raw material, 13% water-retaining agent, 10% loosening agent and 13%-15% bentonite.

[0045] The preparation steps of this embodiment are the same as those of the first embodiment, and will not be described in detail here.

[0046] The above-mentioned raw materials are pulverized into 95-105 mesh.

[0047] The above-mentioned steam pressure is not lower than 6 pressures; the drying temperature of the particles is 50-55 degrees.

[0048] The fertilizers made in the above examples are compound fertilizers or blended fertilizers.

[0049] The above-mentioned fertilizer with anti-drought and soil loosening function is added with a soil loosening agent, which increases the gap between the soil particles, and the air is easy to enter, which increases the respiration of the root cells, and the respiration is strengthened, which ...

Abstract

The invention discloses a fertilizer with drought resisting and soil loosening functions and a production method thereof. The fertilizer comprises urea, powdered ammonium phosphate, a powdered potash fertilizer, a humic acid raw material, a water-retaining agent and a soil loosening agent bentonite. The production method comprises the following steps: mixing the urea, the powdered ammonium phosphate, the powdered potash fertilizer, the humic acid raw material, the water-retaining agent and the bentonite raw material; crushing the uniformly mixed raw materials; preparing the crushed raw materials into granules under steam pressure conditions, and drying the prepared granules; cooling the dried granules, and carrying out sieving; or respectively preparing the urea, the powdered ammonium phosphate, the powdered potash fertilizer, the humic acid raw material, the water-retaining agent and the bentonite raw material into granules; and mixing the granules, and carrying out sieving. According to the invention, the characteristics of the chemical fertilizer are changed, the soil structure is improved, the resistance characteristics are enhanced, and the quality of seeds is improved.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular to fertilizers with drought-resistant soil loosening functions and a production method thereof. Background technique [0002] Soil drought is due to the lack or shortage of available water in the soil, so that the water absorbed by the plant is less than the water lost by transpiration, so the plant lacks water in the body, cannot maintain normal activities, and even dies. And the soil is easy to agglomerate after a long time, which reduces the air permeability of the roots, just like sealing the roots. [0003] Due to our country's small land and large population, it is urgent to increase food production. The continuous increase in food production has increased the use of nitrogen, phosphorus and potassium in the soil. Heavy dependence on chemical fertilizers causes soil compaction, acidification, and geographic exhaustion. What farmers feel the most is "increasing the use of chemical...
