本实验以一定配比的氮、磷、钾，配合某些化学药剂，在杂交稻生育的中后期进行喷施，光合效率、叶绿素含量、根系活力、同化物向穗部的转移量等均有明显的提高，产量增加显著，但组合间有差异。

Abstract:Our experiments showed when fertilizers N.P, K in a given ratio coordinated with certain chemicals were sprayed on hybrid rice during its middle and late growth stages. its photosynthetic efficiency, chlorophyll content, root system activity and assimilates transported to panicles were all significantly enhanced, and its yield was also markedly increased. There was difference i...
