Abstract

The invention relates to a saline-alkali soil fertilizer and a preparation method thereof. The saline-alkali soil fertilizer comprises decomposed coal, microorganisms, farmyard manure, straw, ardealite, ferrous sulfate, distillers' grains, a nitrogenous fertilizer, a phosphatic fertilizer and a potash fertilizer, wherein the microorganisms comprise nitrogen-fixing bacteria, phosphate solubilizing bacteria, potassium bacteria, fermentation bacteria and photosynthetic bacteria. The preparation method comprises the following steps: S1, mixing straw with farmyard manure, adding ferrous sulfate and the fermentation bacteria for fermentation; S2, adding ferrous sulfate, decomposed coal, microorganisms, ardealite and distillers' grains into the mixture in the S1, mixing and pelleting, so as to obtain fertilizer granules; 3, uniformly mixing and stirring the granules obtained in the S2 with the nitrogenous fertilizer, the phosphatic fertilizer and the potash fertilizer, so as to obtain the saline-alkali soil fertilizer. By adopting the fertilizer, the saline-alkali soil can be effectively reformed.

Description

technical field [0001] The invention relates to an agricultural fertilizer in the field of agriculture, in particular to a fertilizer for saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali land is an important land resource, and it is a soil type widely distributed on the earth. The area of ​​saline soil in the world is about 1 billion hectares, and my country has 99.13 million hectares, or about 1.47 billion mu; more than 100 cities in the country are located in saline-alkali land distribution areas, and the agricultural land has lost nearly 50% of the agricultural land due to salinization. million mu, mainly concentrated in the arid and semi-arid regions of North China, Northwest and Northeast China. [0003] Saline-alkali land can be divided into three types according to the causes: 1. Naturally formed saline-alkali land. Mainly distributed in coastal areas, caused by years of seawater leaching. 2. Saline-alkali land caused ...
