Ecological organic fertilizer for saline-alkali soil

Abstract

The invention relates to the technical field of improvement of saline-alkali soil and in particular relates to an ecological organic fertilizer for saline-alkali soil. The ecological organic fertilizer comprises corresponding components in parts by weight: 33-40 parts of cake fertilizers, 30-38 parts of attapulgite, 27-37 parts of chicken manure, 22-28 parts of rotted leaves, 22-28 parts of sesbania, 18-23 parts of dry quicksand, 18-25 parts of ammonium nitrate, 10-20 parts of monoammonium phosphate, 7-12 parts of potassium sulfate and 3-6 parts of microbial powder. The cake fertilizer and thechicken manure contain lots of organic matters and are capable of reducing saline alkali property of the soil; the attapulgite is a clay mineral, has unique laminated structure characteristics, highwater absorption property and a certain bonding capacity and can achieve effects of excessive moisture in the chicken manure and sesbania, preventing ventilation influence due to high humidity in thefermentation process and performing anaerobic glycolysis to produce volatile fatty acids, hydrogen sulfide, skatole and the like; and the microbial powder is capable of oxidizing ammonia ions into nitrate ions to be dissolved into water and preventing the ammonia ions from being degraded into ammonia gas to avoid overflowing.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, and specifically relates to an ecological organic fertilizer for saline-alkali land. Background technique [0002] Saline-alkali land means that the land is affected by natural or human factors, causing salt substances to gradually penetrate into the soil, so that the soil contains more salt and alkali, and makes this type of land unusable. The saline-alkali land in China is roughly distributed The area is in the northwest, northeast, north China and coastal areas. The main reason for the formation of saline-alkali land is that the land in relatively arid areas evaporates into water vapor and is discharged into the air, but the salt in the water cannot be eliminated and remains in the air. In the soil, after a long period of accumulation, the salt in the soil gradually increases, thus forming a saline-alkali land. Because the saline-alkali soil itself contains too much salt...

[0002] Saline-alkali land means that the land is affected by natural or human factors, causing salt substances to gradually penetrate into the soil, so that the soil contains more salt and alkali, and makes this type of land unusable. The saline-alkali land in China is roughly distributed The area is in the northwest, northeast, north China and coastal areas. The main reason for the formation of saline-alkali land is that the land in relatively arid areas evaporates into water vapor and is discharged into the air, but the salt in the water cannot be eliminated and remains in the air. In the soil, after a long period of accumulation, the salt in the soil gradually increases, thus forming a saline-alkali land. Because the saline-alkali soil itself contains too much salt, according to the principle of plant cell osmosis, it is difficult for plant cells to absorb inorganic nutrients and water. As a result, plants die due to the lack of inorganic nutrients and water, thus causing a vicious cycle of saline-alkali ecology. Applying ecological organic fertilizers in saline-alkali land can improve the soil structure of saline-alkali land, increase soil fertility in saline-alkali land, and then change the ecology of saline-alkali land from a vicious cycle to A virtuous circle increases the area of ​​arable land; the main components of existing ecological organic fertilizers are generally fermented manure, which contains rich nutrients, but manure will produce stench during the fermentation process, although the stench will not cause serious health problems to the human body , but it will have a great psychological impact on people, causing nausea and vomiting and other reactions, and causing air pollution. Therefore, stench is an important factor affecting saline-alkali land governance. It is necessary to develop a saline-alkali land that can improve saline-alkali land and has no stench Ecological organic fertilizer
