摘要
对华南农业大学农学院研制的超级稻专用肥与常规方法施肥进行了比较试验。结果表明,超级稻专用肥与常规施肥比较,能显著提高三系超级杂交稻天优998和两系超级杂交稻培杂泰丰的产量,实际产量增幅分别为7.76%和6.07%;促进超级稻品种早生快发,增加有效穗;提高超级稻LAI和群体生物产量及齐穗后21d籽粒的SS活性,增加每穗实粒数。施用超级稻专用肥对超级稻具有一定的强"源"、活"库"效果,从而增产。
A comparison test was conducted between the treatments of a super rice special fertilizer （SSF） developed by the Agriculture College of South China Agricultural University and the conventional fertilization （CK）. The results showed that, compared with CK, SSF increased significantly the grain yields of the three-line super hybrid rice Tianyou 998 （V1） and the two-line super hybrid rice Peiza Taifeng （Vp） by 7.76% and 6.07%, respectively. It was found that SSF promoted earlier and faster growth, increased effective panicles and filled grains per pani- cle, raised LAI and biological yield of population and improved SS activity of grains 21 days after full heading stage. The application of SSF has an effect on enhancing source and activating sink, so it could increase the grain yield of super hybrid rice.
