Peanut is an economically important oil crop worldwide.A recurrent challenge to peanut industry is the significant loss caused by aflatoxin contamination.Knowledge of molecular mechanisms underlying host resistance could facilitate the genetic improvement of peanut.In order to comprehensively understand the molecular mechanisms of peanut resisting A.flavus,we screened out a NBS-LRR class gene-AhRAF42 employing peanut high density microarray,which was down-regulated eight fold by A.flavus under drought stress.

采用田间定位试验的方法,研究了长期不同施肥对双季稻产量和土壤肥力的影响.试验处理如下:①不施肥(CK);②施用常量化学N、P肥(NP);③施用常量化学N、K肥(NK);④施用常量化学N、P、K肥(NPK);⑤施用常量化学N、P、K肥+全量秸秆还田+绿肥(FOM);⑥2/3化学N、P肥+1/3化学K肥+1/2秸秆还田+绿肥(ROM).结果表明,1999-2009年双季稻系统耕层土壤有机碳(SOC)含
玉米单粒、覆膜、精播、高效栽培技术以耐密植品种(如郑单958、先玉335等)为基础,首先设计了集平地、覆膜、施肥、打孔、覆土、镇压、单粒精播一体化的小型播种机;然后深入研究了种植密度、配方施肥、覆膜技术、单粒精播技术等对玉米生产的影响,最后建立了完整的玉米抗旱、增产、节本精播栽培标准技术.
