采用大田试验,研究了3种麦茬处理方式平茬(RS)、立茬(HS)、除茬(ZS)对夏玉米荧光参数日变化及产量的影响。结果表明,Fo的日变化表现为早晨和傍晚弱光下值较小,中午强光下值较大;而Fm、Fv、Fv/Fm、Fv/Fo在早晨和傍晚的值较大,在中午强光下达到一天中的最低值。处理间比较,Fo、Fv/Fm和Fv/Fo总趋势为RS>HS>ZS,Fm和Fv表现为ZS>HS>RS。两年3点的试验均表现为平茬产量最高,除茬产量最低。
Field experiment was conducted to study the effects of stubble (RS), stubble (HS) and stubble (ZS) on the daily variation of fluorescence parameters and yield of summer maize. The results showed that the diurnal variation of Fo was lower in low light in the morning and evening, but larger in noon light, while the values of Fm, Fv, Fv / Fm and Fv / Fo were higher in the morning and evening, Glare reached the lowest value of the day. The total trend of Fo, Fv / Fm and Fv / Fo was RS> HS> ZS, Fm and Fv were ZS> HS> RS. Three years of two years of tests showed the highest yield of stubble, in addition to crop yield the lowest.
