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。
South China Agricultural University College of Agriculture developed super special fertilizer and conventional methods of fertilization were compared. The results showed that the yield of super hybrid rice Tianyou 998 and two-line super hybrid rice Pei Taifeng was significantly higher than that of conventional fertilization, with the actual yield increased by 7.76% and 6.07%, respectively. Early varieties of fast-growing varieties, increase effective panicle; improve super rice LAI and population bio-yield and SS activity of 21 d after heading, increase the number of grains per panicle. Application of super-special fertilizer for super-rice has a strong “source”, live “library ” effect, thereby increasing production.
