Abstract

The invention belongs to the technical field of saline-alkali soil improvement, and particularly relates to an ecological organic fertilizer for saline-alkali soil improvement as well as a preparation method and application thereof, and the organic fertilizer comprises the following components in parts by weight: 30-70 parts of livestock manure, 10-50 parts of citric acid residue, 5-15 parts of humic acid, 1-10 parts of plant ash, 2-15 parts of ammonium bicarbonate and 0.5-2 parts of trace elements. The organic fertilizer disclosed by the invention has the characteristics of no pollution, quick effect, long effect and the like, has a relatively good effect on improvement of the saline-alkali soil, has a relatively good yield increasing effect on crops planted in the saline-alkali soil, is relatively high in nutrient content and relatively low in cost, and has relatively high practical value and a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to an ecological organic fertilizer for saline-alkali land improvement. Background technique [0002] According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world has reached 954.38 million hectares, of which the area of ​​saline-alkali land in China is 99.13 million hectares. Soil salinization has become a global environmental problem. The formation of saline-alkali land is mostly related to the accumulation of carbonate in the soil. Therefore, the degree of alkalinity in saline-alkali land is generally high. Plants in severe saline-alkali soil areas can hardly survive, which has brought great obstacles to agricultural production. Under the background of my country's increasing demand for food, shortage of cultivated land resources, and increasingly urgent ecological environment construction, solving the problem of i...
