Anti-wilting organic fertilizer for saline-alkali land and preparation method thereof

Abstract

The invention discloses the technical fields of saline-alkali land improvement and highly-efficient fertilizer application, and specifically relates to the fields of an anti-wilting organic fertilizerfor a saline-alkali land and a preparation method thereof. The anti-wilting organic fertilizer is composed of the following raw materials in parts by weight: 28 to 40 parts of pig manure, 27 to 38 parts of straw, 22 to 30 parts of urea, 16 to 24 parts of calcium superphosphate, 12 to 20 parts of wood vinegar, 12 to 18 parts of potassium humate, 0.7 to 0.9 part of ferrous sulfate, 0.2 to 0.6 partof malic acid, 0.1 to 0.5 part of oleic acid and 0.1 to 0.4 part of diethyl aminoethyl hexanoate. According to the invention, the malic acid and the oleic acid are organic acids, and can promote reinforcement of nitrogen metabolism of a plant root system, improve vitality of a root system and synthesize more proteins when applied to soil, so the development of the root system is promoted; the dryweight of the root system is increased; the nutrient absorption ability of a plant is improved; and the occurrence of the situation of irreversible wilting due to blockage of a dredging system causedby insufficient nutrients and overabundant salt in a plant body is prevented.

Description

Technical field [0001] The invention relates to the technical field of saline-alkali soil improvement and high-efficiency fertilization, and the specific field is a saline-alkali soil anti-wilting organic fertilizer and a preparation method thereof. Background technique [0002] Saline-alkali land means that the land is affected by natural or man-made factors, causing salt substances to gradually penetrate into the soil, which makes the soil more salty and alkaline, and makes this type of land unusable. China's saline-alkali land 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 water in the arid areas is evaporated into water vapor under the action of evaporation, and is discharged into the air, but the salt in the water cannot be eliminated and stayed in the air. In the soil, after a long time of accumulation, the salt in the soil gradually increases, thus forming sa...

Problems solved by technology

[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. The saline-alkali soil itself contains too much salt, resulting in a high salt concentration in the soil and high osmotic pressure, which inhibits the selective absorption of nutrients by plant roots. The ability of ions, non-nutrient substances invade plants in large quantities, disrupt the normal ion balance in plants, interfere with the normal metabolic functions of plants, destroy protein synthesis and hydrolysis, cause a large amount of ammonia and soluble salts to accumulate in the body, and cause plant dredging system Blockage, causing damage to the vascular bundles of roots or main stems and causing irreversible wilting, usually irreversible wilting will hinder plant growth and development and eventually cause plant death; although existing organic fertilizers in saline-alkali land can reduce soil salinity, they are not effective in improving plant roots. The function is lacking, promoting the growth of plant roots can prevent the phenomenon of high salt solution concentration in the soil caused by a large amount of water evaporation, and the plant root exudates are usually viscose and organic acids, and viscose can promote aggregates in the soil Formation, so as to prevent soil compaction, organic acid can adjust soil pH value, and soil salt concentration and pH value drop will also provide a good growth environment for plant roots, the two complement each other, so it is necessary to develop a kind of salt-alkali-reducing and promoting The organic fertilizer with root function can double guarantee the wilting phenomenon of plants in saline-alkali soil
