“施丰乐”在大麦新品种闽麦02上的应用效果

Results of "Shi Feng Le" Applied in New Barley Variety Minmai02

采用“施丰乐”1 g/666.7 m2,配成40 mg/kg水溶液,在大麦新品种闽麦02上喷施,能有效提早大麦成熟期、增加籽粒产量。其中在分蘖期1次性喷施,主要是通过增加单位面积上的有效穗而获得增产;而在孕穗期1次性喷施、或在分蘖期、孕穗期分2次喷施,则主要通过增加穗粒数和千粒重而获得增产。且后两者均比前者喷施的效果更好、增产更显著,而后两者间的增产幅度相近,差异不显著。

Spraying ＂Shi Feng Le＂ solution with content of 40 mg/kg and dosage of 1 g/666.7 m^2 on new barley variety Minmai02, early maturation and increased grain yield were observed. The effect of spraying one time at the tillering stage was mainly on increasing ears per m^2, and the effects of spraying one time at the booting stage or two times at the both tillering and booting stages were mainly on increasing grains per ear and 1 000 - grain weight. The effectiveness on yield of spraying at the later stages was higher than that at the tillering stage, and no marked differences were observed between later two soraving treatments.
