We explored the feasibility of the substitution of straw returning to nitrogen fertilizer and its effects on nitrogen accumulation under continuous cropping in cold region. A frame culture and continuous positioning experiment was carried out in the experimental site of Northeast Agricultural University from 2017 to 2019, with 15 N labeled urea. A three-factor split-plot design was adopted in this experiment, the main plot was straw returning method with no straw returning (S0) and straw returning (S1), and the sub-plot was nitrogen application levels with 0 (N0), 175 (N1), and 350 (N2) kg hm –2 . Two application methods were set for each fertilizer application amount, one ratio of base fertilizer and top dressing applied was 1:1, and the other ratio of base fertilizer and top dressing applied was 1:0. The results were as follows: When the straw returning amount was 12 t hm –2 , the returning straw could replace 36.8 kg hm –2 pure nitrogen. The average amount of maize straw was 46.50 million tons in Heilongjiang Province from 2017 to 2019, and straw returning could replace 142,700 tons pure nitrogen. The replace amount of pure nitrogen in the ratio of base fertilizer and top dressing (1:1) was 26.88% higher than that in 1:0. Straw returning was negatively correlated with nitrogen use efficiency in maize. The average nitrogen use efficiency of maize in S0 treatment was 6.09% higher than S1 treatment, and the yield of S1 treatment was 4.66% higher than S0 treatment when the urea application amount was 350 kg hm –2 (161 kg hm –2 pure nitrogen). The highest yield of maize was 268.22 g frame –1 in the treatment of straw returning and topdressing with commonly fertilizer applied in local agriculture. In conclusion, the nitrogen substitution effect was remarkable under maize straw returning in Northeast China. Long-term combined application of crop straw and nitrogen fertilizer significantly improved the biomass, yield, and nitrogen accumulation of maize, which was a cultivation mode for increasing yield and efficiency of maize in Northeast China.","PeriodicalId":52132,"journal":{"name":"Acta Agronomica Sinica(China)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42570687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arbuscular mycorrhizas (AM) fungi are widely distributed. Researches have shown that AM fungi infecting plant roots can promote nutrient absorption and growth of plants. In this study, pot experiment was used to set up with two fertilization levels of conventional fertilization (N) and reduced fertilization (R), and inoculated (AM) and control (CK). There were four treatments in total, and four replicates were set in each treatment. The results revealed that the plants inoculated with AM fungi did not only significantly increased the biomass accumulation, but also significantly affected the pH value, alkali hydrolyzable nitrogen and available phosphorus of sugarcane rhizosphere soil. The biomass accumulation in the AM fungus inoculation treatment under reduced fertilization was significantly higher than that of conventional fertilization. The turquoise module and darkgreen module with high specificity with nutrient phenotypes such as nitrogen and phosphorus were screened by weighted gene co-expression network analysis (WGCNA). The core genes of the module were screened with KME value greater than 0.7 as the threshold, and 408 and 21 core genes were screened, respectively. GO enrichment indicated that these core genes were mainly involved in nutrient transport, metabolism, and enzyme catalysis pathways. Based on annotation information and the connectivity of genes, 28 core genes related to the absorption and transportation of nutrients such as nitrogen and phosphorus and 108 related candidate genes were detected among the core genes screened. This study reveals the effects of AM fungi on sugarcane nutrient absorption, and provides a theoretical basis for further understanding of the molecular mechanisms of AM fungi affecting sugarcane nutrient absorption.","PeriodicalId":52132,"journal":{"name":"Acta Agronomica Sinica(China)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43481594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rice is an important food crop in China, but it is severely affected by multiple adverse environmental factors during growth period. It has been found that AP2/ERF transcription factors play important roles in stress response in rice. In this paper, we reviewed the classification and structure architecture of rice AP2/ERF transcription factors and summarized the function and molecular mechanism of different AP2/ERF subfamilies in rice response to disease, drought, saline, and low temperature stresses. This study provides a reference for further interpretation of the molecular network of rice AP2/ERFs-mediated regulatory network in stress responses and their application potential for stress resistance improvement of rice cultivars.","PeriodicalId":52132,"journal":{"name":"Acta Agronomica Sinica(China)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41517286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
