Nitrous oxide (N2O) is a major greenhouse gas (GHG) product of intensive agriculture. The application of nitrogen fertilizer can increase the N2O emissions, and the amount of N2O from fertilizers accounted for 25%-82% of the total soil N2O emissions. Therefore, in order to addressing the serious problems in the agricultural production, such as lower nitrogen fertilizer utilization ratio, increased N2O emissions and declined economic benefit caused by unreasonable nitrogen fertilizer application, a field experiment were conducted to study the effect of different nitrogen fertilizer application patterns on characteristics of N2O emissions and the economic benefit in a summer maize-winter wheat field. The 7 patterns of nitrogen application in the summer maize and winter wheat seasons were control (CK), farmer's nitrogen fertilization pattern (FN), recommended nitrogen fertilization pattern (RN), recommended N rate with dicyandiamide (RN+DCD), recommended N rate with nitrapyrin (RN+CP), recommended N rate with controlled-release fertilizer (RN+CR), recommended N rate with nanocarbon (RN+NC). The CK was without applications of nitrogen fertilizer. During summer maize and winter wheat seasons, the nitrogen fertilizer of FN treatment was 392 and 285 kg/hm2, and the nitrogen fertilizer of the recommended nitrogen treatments (RN, RN+DCD, RN+CP, RN+CR and RN+NC) were 300 and 225 kg/hm2 respectively. The N2O emission from soil was collected by static chamber method and the gas samples were determined by gas chromatography with Agilent7890.The total income obtained from the crop grain minus the cost of the fertilizer and other field management costs was recognized as net income. The results showed that, compared to the treatment of FN, the average N2O emission flux of recommended nitrogen treatments (RN, RN+DCD, RN+CP, RN+CR and RN+NC) were reduced by 29.2%-65.4% (P<0.05) and 26.9%-74.9% (P<0.05) during summer maize and winter wheat seasons respectively, and the total N2O emissions were decreased by 1.05-2.72 kg/hm2 (P<0.05) and 1.10-2.47 kg/hm2 (P<0.05), respectively. In the rotation season, the net income increased by 967.5-3887.0 Yuan/hm2 compared to that of FN treatment. Compared to the treatment of RN, the average N2O emission flux of the treatments of RN+DCD, RN+CP and RN＋CR were decreased by 41.5% (P<0.05), 31.2% (P<0.05) and 5.8% respectively during the summer maize season, and those were decreased by 63.0% (P<0.05), 65.7% (P<0.05) and 25.4% respectively during the winter wheat season. In the rotation season, the total N2O emissions of RN+CP and RN+DCD were decreased by 52.5% (P<0.05) and 49.0% (P<0.05) respectively, and the net incomes of the two treatments were increased by 312.6 and 708.9 Yuan/hm2, respectively. The soil N2O phase emission of peak during the summer maize season appears in the three leaves period to jointing stage and huge bellbottom period to tasseling stage, but during the winter wheat season the soil N2O phase emission of peak appears during the stages of sowing time to seedling stage and the returning green stage to jointing stage. Considering the integrated effects of crop yields, N2O emissions and economic benefit, RN+DCD and RN+CP were recommended for nitrogen management practices which can gain rational crop yield, reasonable income and less negative climatic and environmental impacts.

Through the published literature analysis of wheat and maize field in North China, this study investigated the effects of different management methods of nitrogen(N) application rates, basal/topdressing ratios and N control measures on the soil N2O emission and crop yield. The results showed that reducing N application rates and adjusting basal/top dressing ratios under high N level could decrease soil N2O emissions. Besides, N application with nitrification inhibitor dicyandiamide(DCD) was an effective practice for wheat/maize yield enhancement and soil N2O emission reduction. In order to reduce the soil N2O emission as well as ensure crop yield production in North China, the optimal N application rate of 167~174 kg·hm-2 at basal/top dressing ratio 1:1 with DCD was recommended for wheat production. As a result, soil N2O total emission was 0.31 kg·hm-2 and wheat grain yield reached more than 6200 kg·hm-2. For maize production, the optimal N application rate of 177~181 kg·hm-2 at basal/top dressing ratios 2:3~1:2 with DCD was regarded as the best practice. Soil N2O total emission was 1.70 kg·hm-2 and maize grain yield exceeded 9000 kg·hm-2. [ABSTRACT FROM AUTHOR]

OBJECTIVE:To probe into the economical efficiency of domestic and imported rosuvastatin in treatment of essential hyperlipidemia. METHODS: 1 749 patients with essential hyperlipemia admitted into Laiwu Central Hospital of Xinwen Mining Group from Jan. 2015 to Dec. 2017 were retrospectively selected and divided into group A (857 cases) and group B (892 cases) through different medications. Patients in group A was given domestic rosuvastatin, while group B received imported rosuvastatin. Difference of serum levels [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C), lipid-regulating efficacy, adverse drug reactions and cost-effectiveness analysis of two groups were compared. RESULTS: After treatment of 12 weeks, the TC, LDL-C level of two groups decreased significantly compared with before treatment, yet there was no statistically significant difference between two groups in TC, TG, LDL-C and HDL-C (P >0.05). The total lipid-regulating efficacy of group A and group B were respectively 94.28% (808/857) and 94.17% (840/892), without any statistically significant difference (P> 0.05). One patient in group A developed mild liver drug enzymes, and one patient in group B developed mild diarrhea, which did not affect continued medication, and no other expenses were incurred. The drug cost and cost-effectiveness ratio of patients in group A were significantly lower than those in group B, and the difference was statistically significant (P < 0.05). Patients in group A saved 344.4 yuan for 12 weeks of treatment. CONCLUSIONS: Compared with imported rosuvastatin, domestic rosuvastatin is more economical in treatment of essential hyperlipidemia.
