Problems solved by technology

[0017] At present, most of the fertilizers used in alkaline saline-alkali land are ordinary liquid fertilizers, farmyard manure or organic matter. The nutrient content of fertilizers is between 15% and 25%, and the nutrient content is relatively low. Although it can supplement certain nutrients for the soil, it is ignored. The physical and chemical properties of the soil are not improved, and the nutrients are not easy to release, which neither cures the symptoms nor the root cause; or uses chemical soil amendments combined with mineral fertilizers or organic fertilizers to fertilize, the process is cumbersome, and the amount is difficult to control, which in turn affects the cost of land cultivation.

Abstract

The invention discloses a special organic fertilizer for saline-alkaline soil improvement and a preparation method and application of the special organic fertilizer for saline-alkaline soil improvement. The special organic fertilizer for saline-alkaline soil improvement comprises, by weight, more than 90% of spent bleaching clay bleached by edible fat and oil, and particularly comprises, by weight, 90%-92% of spent bleaching clay bleached by edible fat and oil, 1%-6% of medium trace elements and 2%-9% of saline-alkaline soil improvement materials, wherein the medium trace elements comprise, by weight, 35-65% of potassium sulfate, 30-60% of ammonium sulfate, 1-4% of zinc sulfate and 0.5-2% of sodium borate, and the saline-alkaline soil improvement materials comprise, by weight, 70-100% of desulfurated gypsum powder and 0-30% of sulfur powder. The special organic fertilizer for saline-alkaline soil improvement has the advantages of reasonable organic fertilizer ratio, simplicity in use and capabilities of applying once, regulating a soil pH value and salinity-alkalinity and providing required nutritional ingredients and trace elements for crop growth.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special organic fertilizer for saline-alkali land improvement, a preparation method and application thereof. Background technique [0002] Alkaline soil refers to the soil that contains a large amount of exchangeable sodium ions, which can harm the growth and development of plants and change the soil properties. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. In actual conditions, saline soil and alkaline soil often coexist in a mixed manner, collectively referred to as saline-alkali soil. [0003] In alkaline soil, due to the presence of exchangeable sodium ions on the soil colloidal particles, sodium carbonate and sodium bicarbonate in the soil solution, the soil is alkalized (the pH value can reach above 9), and the soil has adverse phy...
