Nitrogen(N)priming is a microbially mediated biochemical process as affected by different incorporation ***,little information is known about the microbial mechanisms driving the response of N priming to co-operation of Chinese milk vetch(CMV,Astragalus sinicus L.)and different rates of chemical fertilizers in paddy soils in South ***,an anaerobic incubation experiment was conducted to study N priming effects(PE)and their relationships with soil microbial functional genes after CMV incorporation alone(M),co-incorporation of CMV with 100%(normal dosage)chemical fertilizers(MC100),and co-incorporation of CMV with 80% chemical fertilizers(MC80).Co-incorporation of CMV and chemical fertilizers enhanced the short-time scale(the first 20 d of incubation)positive PE of N,while no significant differences existed among the three treatments on day 60 or 90 of incubation(P>0.05).Compared with the M treatment,gross priming effect(GPE)in the MC100 and MC80 treatments significantly increased by 34.0% and 31.3%,respectively,and net priming effect(NPE)increased by 47.7% and 47.8%,respectively,during the first 20 d of incubation(P<0.05).This was likely attributed to soil nutrient availability and added substrate *** MC100 and MC80 treatments increased the gdhA gene abundance by 5.0% and 9.8%,increased the gdh2 gene abundance by 12.7% and 45.7%,and increased the nasB gene abundance by 9.5% and 41.4%,respectively,in comparison with the M treatment on day 20 of *** analyses indicated that soil microbial functional genes involved in N mineralization(gdhA and gdh2),assimilatory nitrate reduction(nasB),and nitrification(amoB)were significantly correlated with N priming under different incorporation practices during the incubation period(P<0.05).Thus,co-incorporation of CMV and chemical fertilizers can regulate soil microbial community functional gene structure,which may accelerate mineralization and assimilatory nitrate reduction and inhibit

为了充分挖掘和利用中国野生植物资源,并将资源植物利用与乡村振兴紧密结合,本文基于植物大数据,兼顾资源植物的经济价值和地域分布,提出利用地标系数遴选各地级行政区的“地理标志资源植物”(简称“地标植物”)。在全国375个地级行政区(即省级行政区管辖的行政单位,包含地级市、盟、自治州、地区、省直辖县级行政区)共遴选出1181种地标植物候选物种,每个地级行政区至少1种;并且,从这些候选物种中遴选出661种地标植物,这些地标植物或具有独特的自然生态环境和人文历史,或已具备产业基础及当地栽培历史,或易规模化生产。从省级行政区看,广东遴选出的地标植物最多(102种),接下来依次为四川、云南和海南,遴选出的地标植物分别有96、86和83种。从地级行政区看,云南省文山壮族苗族自治州、安徽省芜湖市、江苏省淮安市、西藏自治区林芝市遴选出的地标植物最多(8种)。值得注意的是,有17种植物仅为1个地级行政区的地标植物,建议将这类植物开发成“地理标志植物产品”(简称“地标产品”)。另外,还存在1种植物被遴选为多个地级行政区地标植物的情况。对于地理空间上连续的多个地级行政区的地标植物,建议协同当地有关部门打造地标产品,塑造产业集群优势;而对于地理空间上不连续的多个地级行政区的地标植物,则需要突破地域壁垒,创新营销模式,构建营销网络,注重品牌打造,以形成拳头产品。研究结果显示:基于植物大数据可遴选出各地独特的优良植物资源,后续可将地标植物开发成地标产品,避免区域资源植物产业发展同质化,服务地方经济建设,助力乡村振兴。
