Abstract

The invention provides a mixed fertilizer for improving light and moderate saline-alkali soil. The mixed fertilizer comprises the following ingredients in parts by weight: 5-15 parts of humic acid fertilizer, 20-35 parts of water soluble nitrogen fertilizer, 18-25 parts of water soluble phosphate fertilizer, 20-28 parts of water soluble potassium fertilizer, 0.1-0.5 parts of microelement fertilizer, 40-60 parts of semi-coking biomass, 5-10 parts of sodium polyacrylate and 20-26 parts of desulfurized gypsum, wherein the semi-coking biomass is a product of carbonizing treatment of straws at 320-360 DEG C for 1.5-2h; and a pH (potential of hydrogen) value of the mixed fertilizer is 6.5-7. The mixed fertilizer is used for treating the light and moderate saline-alkali soil; physical and chemical properties of the soil are improved obviously; the fertilizer is acidic and can neutralize alkaline of the saline-alkali soil; the pH value of the soil is reduced by 1-2; an alkalization degree of the soil is reduced to below 7% after improvement from 10-20% before the improvement; the hardness of the soil is obviously reduced; the penetrability is obviously improved; and a salt content of the soil is decreased year after year.

Description

technical field [0001] The invention belongs to the field of agriculture and relates to a mixed fertilizer for improving light and moderate saline-alkali land and a preparation method thereof. Background technique [0002] Soil salinization has always been the main obstacle restricting the development of my country's agriculture and the improvement of comprehensive capabilities. If the control and prevention efforts are not strengthened, it will directly affect my country's agricultural production capacity and food security. The deterioration of the ecological environment caused by salinization, It will also affect the living and development space of the people in the irrigation area. Therefore, the prevention and development of saline-alkali land is an issue that cannot be ignored in the agricultural development of the irrigation area. It plays an important role in promoting the sustainable development of agriculture and ensuring food security. [0003] At present, the impro...
