The rice has a long cultivation history in China, the total yield accounts for 44% of the total grain yield of China, the sowing area and the total yield of the rice are the first food crops in China, about 60% of people use the rice as staple food, and the rice has a very important role in the food production of China.
At present, in the rice planting process, a base fertilizer is applied once before seeding or transplanting, after the rice grows to a certain degree, one or two additional fertilizers are applied according to different nutrient requirements of the rice in different growth periods, the additional fertilizers are mainly applied by spreading a nitrogen fertilizer, the nitrogen fertilizer is spread in a rice field for the absorption and utilization of the rice, and the spread surface layer nitrogen fertilizer is easy to decompose and run off. The rice growth mainly absorbs the soil nutrient content through the root system, the absorption and utilization of the soil nutrient by the rice root system are closely related to the position of the soil where the nutrient is located, the nutrient in some areas is far away from the rice root system and is difficult to be absorbed and utilized by plants, and because the fertilizer nutrient in each part of the soil is balanced in the spreading process, the rice root system is difficult to cover most of the soil containing the nutrient, the absorption and utilization of the nitrogen fertilizer by the rice are not facilitated, a large amount of residual nitrogen fertilizer in the rice field is easy to cause, and thus the N-content of the nitrogen fertilizer in the soil is N-content 2 The generation of O provides more substrate, and further causes the rice field to discharge more greenhouse gas N 2 And O. Meanwhile, under the traditional flood irrigation cultivation mode, the rice field soil is in a flooded anaerobic state for a long time, so that the propagation of methane-oxidizing bacteria is facilitated, and the CH content of the rice field is greatly increased 4 The amount of discharge of (c). According to the 5 th IPCC report, methane (CH) 4 ) And nitrous oxide (N) 2 O) isothermal gas concentration has risen to the highest level since history, the emission of greenhouse gases of agricultural origin accounts for about 12% of the total greenhouse gas emission generated by global human activities (IPCC., 2018), and the atmosphere has 50-65% of CH 4 The discharge is generated by artificial activities, paddy CH 4 Annual emission of about 20-40 Tg yr -1 About 10% -20% of the annual emissions worldwide (Stocker et al, 2013), 80% of artificial N 2 O from agricultural production, in which the farmland soil N 2 O emissions have been from 0.3-1.0 Tg N yr of 1850 −1 3.9-5.3 Tg N yr increased to 2010 −1 (Xu et al, 2017).
