Abstract

The invention discloses a method and an apparatus for influencing N2O emission of rice foliage and rhizosphere. According to the method, the test on N2O emission flux of rice foliage and rhizosphere under control of indoor low light level is carried out; the test on N2O emission flux of rice foliage and rhizosphere on conditions of different illuminations and different nitrogen application rates is carried out; calculation and counting of N2O emission flux of rice foliage and rhizosphere are performed, the N2O emission flux of rice on difference conditions is calculated systematically, and finally systematical and scientific analysis and calculation is performed. The method and the apparatus can provide theory and practical foundation for reduction of N2O emission of rice in rice fields and reasonable nitrogen supply in rice production, namely reasonable nitrogen fertilizer application, thereby realizing scientific farming, while effectively protecting the atmosphere environment, lowering planting cost of rice, and increasing yield and income for farmers.

Description

Technical field: [0001] The invention relates to the field of rice planting in agricultural production, in particular to a method of affecting rice leaves, rhizosphere N 2 O emission method and device. Background technique: [0002] Paddy ecosystem is N 2 O is an important emission source, and its emission is closely related to nitrogen application rate and paddy field moisture status. N produced and released by soil 2 O accounts for about 10% of the biosphere's N 2 53% of the total O, agricultural soils are N 2 The main source of O emissions. N emitted by nitrogen fertilizer application 2 O accounted for soil N 2 O 25%-82% of total emissions. Increase the amount of nitrogen fertilizer, N 2 O emissions increase accordingly. Long-term large-scale application of nitrogen fertilizers and the resulting soil acidification will promote N 2 O release, but N 2 The effect of O emission was not significant. Moreover, crops and their nitrogen utilization also have an impor...
