Description

Reduce farmland greenhouse gas exhaust compositions and application thereof
Technical field
The invention belongs to agrotechnique and field of environment protection, particularly one reduces farmland greenhouse gas exhaust compositions and application thereof.
Background technology
A large amount of discharges of greenhouse gases cause Global climate change, particularly climate warming, became the regular topic of people in recent years, cause the great attention of national governments and scientist, international climate change conference is held for years, concentrates government and academia to inquire into Technology of Reducing Greenhouse Gas Emissions and studies climate change to the disadvantageous effect of the mankind.
It is generally acknowledged that greenhouse gases have six large classes, carbonic acid gas, methane, Nitrous Oxide, carbon fluorohydrocarbon, water, ammonia etc., wherein carbonic acid gas, methane, Nitrous Oxide are mainly relevant with agricultural and farming activities.Carbonic acid gas (CO 2) be the products of organism after the aerobic or anaerobic oxidation of oxidizing microorganisms all kinds of in soil such as the crop material remained in agricultural land soil, carcase and fertilizer; Nitrous Oxide (N 2o) be that in air, content is only second to CO 2and CH 4important greenhouse gases, be mainly derived from nitrated, nitrosification and motor vehicle exhaust, the lightning etc. of soil nitrogen; N 2o also can strong absorption infrared rays, reduces earth's surface by the thermal radiation of air to outer space, thus causes Greenhouse effect, have important impact to global environment and climate change.N 2o is stable in properties in troposphere, heats potentiality huge, and its Greenhouse effect are 290-310 times of same concentration carbonic acid gas; Methane (CH 4) be one of main greenhouse gas, it accounts for 20% ~ 39% (IPCC, 2007) to the contribution of Global warming.CH in air 4content is 0.72 μm of olmol of (1750) before the Industrial Revolution -1rise to 1.77 μm of olmol of 2005 -1, increase about 2.5 times, and CH 4molecule has very strong infrared absorbance, and it is CO that its unit molecule heats potentiality 219-25 doubly (IPCC, 2007), therefore CH 4be considered to the CO that continues 2one of most important greenhouse gases afterwards, it produces, consume and emission mechanism remains the hot issue studied at present.In soil anaerobic environment, under methanogen effect, produce CH by anaerobically fermenting based on the organic substance of waterplant root exudates and cast and the soil organism 4, so wetland becomes one of Major Natural approach of greenhouse gas methane discharge.
Methane mainly occurs in the rice field of waterflooding, farmland greenhouse gas main in upland soil is carbonic acid gas and Nitrous Oxide, wherein Nitrous Oxide is the main source of greenhouse gases Nitrous Oxide, mainly due to the excessive nitrogenous fertilizer of agricultural application caused by the oxygenizement of nitrifying microorganisms and denitrifying microorganism or reductive action.
The research of agricultural land soil Technology of Reducing Greenhouse Gas Emissions, will provide new technology and method for agricultural reduces discharging, and for human kind sustainable development provides safeguard, for realizing low-carbon high-efficiency agricultural, Agricultural Sustainable Development provides technical foundation.
Summary of the invention
the technical problem solved:the present invention is directed to farmland greenhouse gas emission problem, develop a kind of simple method, there is provided a kind of and reduce farmland greenhouse gas exhaust compositions and application thereof, this method is before crop seeding, in land for growing field crops fertilising simultaneously, use phosphogypsum etc. and reduce discharging material, the discharge of the farmland greenhouse gas during a lot of plant growth such as whole wheat, corn, paddy rice, cotton can be greatly reduced, promote the growth of some crops such as wheat, corn, paddy rice, cotton, improvement and raising soil productivity, improve crop quality, increase peasant economy benefit.
technical scheme:reduce farmland greenhouse gas exhaust compositions, consist of every 1000 kilograms of phosphogypsum slags and add 5-100 kilogram of xanthohumic acid, 0.5-20 kilo sulfuric acid copper, 0.1-5 kilogram of sodium ethylene diamine tetracetate.
Described composition is reducing the application in farmland greenhouse gas discharge, step is: a. adds xanthohumic acid, copper sulfate and sodium ethylene diamine tetracetate in phosphogypsum slag, every 1000 kilograms of phosphogypsum slags add 5-100 kilogram of xanthohumic acid, 0.5-20 kilo sulfuric acid copper, 0.1-5 kilogram of sodium ethylene diamine tetracetate, mix thoroughly, pulverize; B., before crop sowing, step a gained mixture is evenly spread fertilizer over the fields soil surface; Use 30-160 kilogram for every mu; C. normally apply fertilizer, plough soil, sowing wheat, corn, paddy rice or cotton crop.
One of preferred version, every 1000 kilograms of phosphogypsum slags add 5 kilograms of xanthohumic acids, 0.5 kilo sulfuric acid copper, 0.1 kilogram of sodium ethylene diamine tetracetate; Use 30 kilograms for every mu.
Preferred version two, every 1000 kilograms of phosphogypsum slags add 15 kilograms of xanthohumic acids, 1.0 kilo sulfuric acid copper, 0.2 kilogram of sodium ethylene diamine tetracetate; Use 60 kilograms for every mu.
Preferred version three, every 1000 kilograms of phosphogypsum slags add 30 kilograms of xanthohumic acids, 1.0 kilo sulfuric acid copper, 0.8 kilogram of sodium ethylene diamine tetracetate; Use double centner for every mu.
Preferred version four, every 1000 kilograms of phosphogypsum slags add double centner xanthohumic acid, 20 kilo sulfuric acid copper, 5 kilograms of sodium ethylene diamine tetracetates; Use 160 kilograms for every mu.
Above-mentioned composition reduces the application in farmland greenhouse gas discharge when wheat, corn, paddy rice or cotton crop are planted.
beneficial effect:the present invention can reduce the discharge of farmland greenhouse gas, promotes plant growth evil; Its maximum function reduces the discharge of farmland greenhouse gas.
The present invention can greatly reduce the discharge of farmland greenhouse gas particularly carbonic acid gas, Nitrous Oxide, increases soil fertility, is conducive to development and the agricultural sustainable development of the ecological agriculture.
