摘要
为了利用农艺措施与化控技术相结合提高作物茎秆强度,在盆栽条件下研究了苗期镇压与矮壮素处理对小麦生育和基部茎秆发育的影响。结果表明:苗期镇压和矮壮素喷施使小麦株高降低,基部节间缩短、变粗,生育期延迟,有效分蘖数、小穗数和穗粒数增加,与未处理对照的差异都达到显著水平。另外,处理还提高了小麦基部茎秆的纤维素含量,为增加茎秆的物理强度提供了物质基础。该试验虽在盆栽条件下完成的,但所得到的结果对大田生产仍有一定的参考价值。
In order to increase stem intensity of wheat by agronomy method combining with chemical tech nigues,the effect of rolling and spraying TUR at seedling stage by pot experiment were investigated. The re sults showed that combination treatment of rolling and spraying TUR at seedling stage reduced plant height, staorten and widen base internodes, delayed growth duration,increased effective tillers, spikelet and grains per spike, the differences reach significant or extremely significant level compared to the control. In addition, the combination treatment of rolling and spraying TUR increased acid detergent fiber（ADF）and neutral detergent fiber（NDF）. Though it was the pot experiment,the study results possessed important reference value for field practice.
