Abstract

The invention relates to a fertilizer applicable to saline-alkali soil. The fertilizer is characterized by being prepared from zeolite, weathered coal, a microbial agent, excrements of livestock, edible mushroom dregs, a water-retaining agent, turf, kitchen waste products and inorganic fertilizers. A preparation method of the fertilizer comprises the following steps: S1, mixing crushed edible mushroom dregs and excrements of livestock, adjusting a carbon nitrogen ratio of the mixture to be 25 / 1 to 30 / 1, and then adding the microbial agent for fertilizing; S2, adding the weathered coal, the zeolite, the turf and the kitchen waste products to the fertilized mixture in step S1, and then mixing and granulating to obtain fertilizer particles; S3, mixing the particles obtained in the step S2 and the water-retaining agent, and then uniformly stirring to obtain the fertilizer applicable to the saline-alkali soil.

Description

technical field [0001] The invention relates to an agricultural fertilizer in the field of agricultural production, in particular to a fertilizer suitable for saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali soil is a collective term for saline soil and alkaline soil. According to incomplete statistics from UNESCO and FAO, the global saline-alkali soil area has reached 9.5×10 8 hm 2 and each year by 1.0×10 6 ~1.5×10 6 hm 2 speed growth. The area of ​​saline-alkali soil in China is 3.7×10 7 hm 2 Almost all over the country. Soil salinization not only reduces soil productivity, but also causes many ecological and environmental problems. [0003] Saline-alkali land is an important land resource. It is a land type widely distributed on the earth, accounting for about 25% of the total land area, with a total of about 1 billion hectares, distributed in arid regions on all continents. my country has about 27 million hectares...
