通过10个玉米品种分别进行去除分蘖与保留分蘖的试验,对玉米品种分蘖率、生物学性状、产量及产值等进行研究,结果表明,不同玉米品种植株分蘖数量差异明显。同一玉米品种去除分蘖与保留分蘖对植株抽雄和吐丝的生育过程没有影响,对叶片SPAD值、叶面积系数、干物质重、产量及构成因素均无显著影响,但是玉米去分蘗后的亩产值明显小于留分蘖的亩产值。本项研究结果为减少玉米生产环节投入,提高玉米生产效率提供有力的理论支撑。
Ten corn cultivars were used to remove tillers and retain tillers respectively. The tillering rate, biological characters, yield and yield of maize varieties were studied. The results showed that there were significant differences in tillering numbers among different maize varieties. The removal of tillers and tillers from the same maize cultivars had no significant effect on the plant growth and tasselling process, but had no significant effect on leaf SPAD, leaf area index, dry matter weight, yield and composition. However, Significantly less than the remaining tillering of mu output value. The results of this study provide a strong theoretical support for reducing maize production inputs and increasing maize production efficiency.
