摘要
探讨玉米抗倒增产剂对陕北高密度下春玉米株高和穗位和根茎叶以及生物学产量的影响,为陕北玉米密植抗倒高产高效栽培提供依据.示范方法是在玉米7～9 叶时期,喷施吨田宝玉米抗倒增产剂.结果表明,年均株高降低50.8 cm,穗位年均降低23.2 cm,生物学产量增0.01 kg/株,百粒重增2.5 g,含水率减低2.95%,产量增加187.3 kg/667 m2.喷施吨田宝玉米抗倒增产剂,能提高陕北高密度春玉米抗倒伏和生物学产量.
Abstract
To investigate the effects of maize lodging resistance and yield-increasing agents on different pa-rameters including plant height,ear position,root-shoot-leaf ratio,and biological yield of spring maize culti-vated under high-density conditions in northern Shaanxi,the aim is to lay a foundation for the implementation of high-density,lodging-resistant,and high-yielding maize cultivation practices in the region.The experimen-tal approach was to apply"Tuntianbao"maize lodging resistance and yield-enhancing agent during the 7～9 leaf stage of maize growth.The results indicated a significant decrease in average annual plant height by 50.8 cm,a reduction of average ear position by 23.2 cm,an increase in biological yield by 0.01 kg/plant,a rise in hundred-grain weight by 2.5 g,a decrease in moisture content by 2.95%,and a yield increase of 187.3 kg/667 m2.Application of the"Tuntianbao"agent demonstrated its potential to enhance lodging resistance and biological yield of spring maize in high-density planting regions of northern Shaanxi.
