为探究磷肥运筹对双季稻产量与氮、磷、钾素吸收利用的影响,以湘早籼45号(早稻)和泰优553(晚稻)为材料,在3个施磷(P2O5)水平(P45:45 kg/hm2展开更多 为探究磷肥运筹对双季稻产量与氮、磷、钾素吸收利用的影响,以湘早籼45号(早稻)和泰优553(晚稻)为材料,在3个施磷(P2O5)水平(P45:45 kg/hm2;P75:75 kg/hm2;P105:105 kg/hm2)与2个施用时期(全基肥,S1;基肥:穗肥=2:1,S2)下开展机插试验。结果表明,施磷量增大可提高水稻干物质积累量,并且对产量及其构成因素影响显著,但施用时期无显著影响。施磷量与施用时期对产量具有一定的互作效应,早、晚稻产量均以P75处理显著较高,早稻以P75S1处理最高,而晚稻以P...

In order to investigate the effects of P fertilizer management on the yield and nitrogen,phosphorus and potassium uptake and utilization of double-cropping rice,Xiangzaoxian 45(early rice)and Taiyou 553(late rice)were used as materials to carry out the machine planting ...MORE In order to investigate the effects of P fertilizer management on the yield and nitrogen,phosphorus and potassium uptake and utilization of double-cropping rice,Xiangzaoxian 45(early rice)and Taiyou 553(late rice)were used as materials to carry out the machine planting test under three phosphorus application levels(45 kg...
