Embodiment 1

[0034] The saline-alkali soil improvement fertilization conditioner is made of the following raw materials in weight percent: 60% of sludge organic fertilizer, 15% of desulfurized gypsum, 14% of phosphogypsum, 5% of superphosphate, 5% of ammonium sulfate, and 1% of ferrous sulfate. %, appropriate amount of plant growth regulator;

Embodiment 2

[0036] The saline-alkaline soil improvement and fattening conditioner is made from the weight percentage of the following raw materials: 50% of livestock and poultry manure organic fertilizer, 20% of desulfurized gypsum, 19% of phosphogypsum, 5% of superphosphate, 5% of ammonium sulfate, ferrous sulfate 1%, appropriate amount of plant growth regulator;

Embodiment 3

[0038] The saline-alkaline soil improvement and fattening conditioner is made of the following raw materials in weight percent: 40% of livestock and poultry manure organic fertilizer, 5% of furfural slag, 20% of desulfurized gypsum, 15% of phosphogypsum, 8% of superphosphate, and 2% of ammonium sulfate. %, lignite 10%.

[0039] Production method: Inorganic materials are mixed evenly after microbial fermentation treatment,

Abstract

The invention discloses a fertilizing and conditioning agent for improving the saline alkali soil, and the fertilizing and conditioning agent includes an organic material, an inorganic material and a regulator for the plant growth, wherein, the weight proportion between the organic material and the inorganic material is 3:2 to 1:1. The organic material is fermented and maturated by one or a plurality of such organic matters as town living sludge, excrements of livestock and poultry, and furfural slag; and the inorganic material is formed by one or a plurality of such industrial waste and materials as desulfurized gypsum, phosphogypsum, and ammonium sulphate. Moreover, appropriate growth regulator for plant which is added according to the growing requirements can not only improve the saline alkali soil and fertilize the soil, but also can improve the plant growth and promote the plant to grow well as well as providing an effective path for promoting the recycling of the waste resources and reducing the secondary pollution to the town and the country.

Description

technical field [0001] The invention relates to a conditioner for saline-alkali soil improvement and fertilization and a preparation method thereof, and especially provides a new way for resource recycling of industrial and agricultural waste. Background technique [0002] In recent years, the state has put forward a technical policy of "harmless, resourceful, and volume reduction" to control industrial waste pollution. In May 2005, the National Development and Reform Commission issued "Several Opinions on Accelerating the Industrialization of Flue Gas Desulfurization in Thermal Power Plants", which clearly required to speed up the process of flue gas desulfurization in thermal power plants and strictly control SO 2 Discharge air pollution to protect the ecological environment. [0003] The annual output of solid waste in Tianjin is about 8.04 million tons, including 6.43 million tons of industrial waste. According to statistics, in 2004, the main SO in Tianjin 2 Emission...
