Description
Technical field
The invention belongs to compound manure development field, relate to and utilize nitrification inhibitor and biomass charcoal compounding application to reduce Nitrogen Leaching loss, improve the utilization ratio of nitrogenous fertilizer.
Background technology
Dao Mai crop rotation district, Taihu Lake agricultural land soil amount of application of nitrogen fertilizer can reach annual 500-600kg N/ha (Xing et al., 2001.Sci.China Ser.B), under Protected Cultivation, amount of nitrogen is even up to 1000kg N/ha (Jiang Huimin etc., 2010. agro-environment science journals), and China's farmland utilization rate of nitrogen fertilizer often only has 30% left and right (Zhu Zhaoliang, 1992. Science Press), and (Jiang Jun etc., 2005. Agricultural University Of Nanjing's journals) decline along with the increase of amount of application of nitrogen fertilizer.After nitrogenous fertilizer is manured into soil, by leaching, runoff, volatilization, nitrated-approach such as denitrification, lose, not only cause the waste of fertilizer, the energy, also caused a series of environmental problem, comprise body eutrophication, Nitrate content in ground water increases, soil physics structure deteriorate (Zhu Zhaoliang, 1992. Science Press), crop alimentary imbalance, nitrate content raises, and quality declines, disease and pest is easily sent out (Li Junliang etc., 2003. soil journals) etc.
The method that improves nitrogenous fertilizer utilization comprises: improve nitrogen application mode, and balance fertilizing, Rational Irrigation, is used (Zhu Zhaoliang, 1992. Science Presses) such as slow-release nitrogen fertilizers.Because soil belt negative charge, positively charged ion ammonium nitrogen is had to very strong confinement capabilities, but negatively charged ion nitric nitrogen is had to repulsive interaction (Ippolito et al., 2011.Soil Sci.), use in theory nitrification inhibitor and can hinder ammonium nitrogen to the transformation of nitric nitrogen, reduce the leaching loss of nitrogen, improve utilization rate of nitrogen fertilizer (Zhu Zhaoliang, 1992. Science Presses).Yet because leaching loss occurs nitrification inhibitor itself, cause it to the inhibition of nitration reaction (Bremner et al. lastingly, 1978.Soil Biol.Biochem.), this is also one of reason of not being promoted in the large tropical and subtropical region of China's annual rainfall of nitrification inhibitor.If take certain technical measures to extend the residence time of nitrification inhibitor in soil, can extend its inhibition to nitration reaction, yet the research of at present relevant this respect also seldom.
Agricultural crop straw is as a kind of solid waste, and the harvest season, a large amount of burning caused Air quality severe exacerbation (Lu Ping etc., 2011. China Environmental Sciences; Yin Cong etc., 2011. China Environmental Sciences), how rationally to process, dispose a large amount of crop materials and caused increasing concern.The crop material biomass charcoal that through anaerobism prepared by pyrolysis has higher cation exchange capacity; huge specific surface area and abundant organo-functional group; organic substance is had to stronger adsorptive power and very high loading capacity (Uchimiya et al., 2010.Chemosphere; Beesley et al., 2011.Environ.Pollut.; Xu et al., 2011.Bioresour.Technol.).Many results of study prove, biomass charcoal is applied directly to the nitrogen form that can affect in soil in soil to be changed, and minimizing greenhouse gas emission but can't reduce leaching loss (Sarkhot et al., the 2012.J.Environ.Qual. of Nitrogen In Soils; Bruun et al., 2012.Soil Sci.Soc.Am.J.).By biomass charcoal and nitrification inhibitor compounding application, perhaps can utilize the RETENTION BY SOILS of biomass charcoal to nitrification inhibitor, reduce its leaching loss, extend its inhibition to nitrogen nitrification, thereby reduce the leaching loss of nitrogenous fertilizer.
Summary of the invention
The technical problem solving: the object of this invention is to provide a kind of method and application thereof that utilizes biomass charcoal sticking nitrification inhibitor Dyhard RU 100 (DCD), thereby extend its inhibition to inhibition acid amides state and ammonium fertilizer nitration reaction in soil, reduce the risk of phosphate leaching loss of nitrogenous fertilizer, improve utilization rate of nitrogen fertilizer.
Technical scheme: nitrification inhibitor and biomass charcoal compounding application improve method, nitrification inhibitor Dyhard RU 100 and 300 ℃ of peanut straw charcoal compounding applications of firing of utilization rate of nitrogen fertilizer.
When ammonium state or amide nitrogen fertilizer amount of application are every kilogram of soil 200-400mg N, Dyhard RU 100 consumption is every kilogram of soil 5-50mg, and peanut straw charcoal amount of application is every kilogram of soil 5-50g.
First Dyhard RU 100 is mixed and imposes on topsoil with peanut straw charcoal, and fully mix with soil, then need to use chemical fertilizer according to farm crop.
The application of the method for nitrification inhibitor and biomass charcoal compounding application raising utilization rate of nitrogen fertilizer in rain fed crop plantation.
Beneficial effect:
When add Dyhard RU 100 in soil, due to its restraining effect to nitrated microorganism, ammonium fertilizer is difficult for changing into nitric nitrogen, and soil surface is with negative charge, to positively charged ion NH
4 +there is very strong confinement capabilities, but to anion N O
3 -there is repulsive interaction, cause nitric nitrogen to be easy to rainfall and irrigation water leaching loss.Therefore, nitrification inhibitor has suppressed nitration reaction, has reduced the leaching loss of nitrogen.But because nitrification inhibitor is water miscible, itself is also easily with water leaching, or with runoff loss, therefore inhibiting nitrification effect is also not obvious, especially in the more and higher area of ground water table of annual rainfall, this phenomenon is particularly evident, and the effect that how to improve nitrification inhibitor is that pendulum is at the current a great problem (Zhu Zhaoliang of agricultural sciences worker always, 1992. Science Presses), however for the research of this respect, carry out at present both at home and abroad also seldom.If add biomass charcoal when using nitrification inhibitor, perhaps can utilize biomass charcoal the RETENTION BY SOILS of nitrification inhibitor to be reduced to leaching or the runoff loss of nitrification inhibitor.
Langxi, the Anhui red soil of take is example, when urea interpolation level is 400mgN/kg, when adding soil that Dyhard RU 100 processes culture experiment finishing through 94 days, accumulative total nitric nitrogen leaching loss is 131.0mgN/kg, and the control treatment nitric nitrogen leaching loss that does not add Dyhard RU 100 has reached 266.0mgN/kg.When Dyhard RU 100 mixes with biomass charcoal while using, nitric nitrogen leaching loss amount is only 33.4mgN/kg.Dyhard RU 100 and biomass charcoal be mixed to be executed, Dyhard RU 100 is processed, control treatment ammonium nitrogen leaching loss amount is respectively 79.8,66.6 and 63.7mg N/kg, and three is more or less the same.Dyhard RU 100 and biomass charcoal be mixed executes that to process total leaching loss amount of two kinds of form inorganic nitrogens minimum.As can be seen here, by biomass charcoal and nitrification inhibitor Dyhard RU 100 compounding application, effectively suppress the nitration reaction of ammonium state and amidonitrogen, reduced the leaching loss of nitric nitrogen.For pursuing high yield, China's farmland amount of application of nitrogen fertilizer is very high, and utilization rate of nitrogen fertilizer is often lower, also causes the disadvantageous effects such as serious body eutrophication, crops quality decline, soil compaction.Compounding application biomass charcoal and Dyhard RU 100, not only reduced the leaching loss of nitrogen, improved utilization rate of nitrogen fertilizer, also reduces loss of nitrogen fertilizer and the pollution to surface water and groundwater thereof; Dyhard RU 100 degradation production in soil is ammonium and carbonic acid gas, can residual harmful substance in soil; Biomass charcoal itself is also a kind of organic fertilizer and soil physics texture modifier, when the nutritive elements such as the required N of crop, P, K, Ca, Mg are provided, can increase soil porosity, improves water retention in soil etc.Therefore, the present invention by adding biomass charcoal and Dyhard RU 100, coordinates plantation rain fed crop as corn, rape, wheat and sesame etc. in fertilising, reach improvement soil physical structure, reducing Nitrogen Leaching loss simultaneously, improve utilization rate of nitrogen fertilizer, is a kind of modification method more friendly to environment.
