为明确多效唑对小麦株高的抑制效应以及对产量的影响,于1986年春季在练湖农场进行了本试验。 供试小麦品种为“7730”,1985年11月26日播种,1986年1月10日出苗,4月28日抽穗。设抽穗前66天、56天、46天和36天(即拔节前30天、20天、10天和拔节始期)喷施多效唑和不喷(对照)5个处理。多效唑处理用量均为每亩12克,四次重复。 试验结果表明,在小麦抽穗前66天到抽穗前36天喷施多效唑,都有抑制株高生长的
In order to clarify the inhibitory effect of PP333 on wheat plant height and the effect on yield, the experiment was carried out in Lianhu Farm in Lianhe Spring in 1986. The tested wheat varieties were “7730”, sown on November 26, 1985, sprouted on January 10, 1986, and heading on April 28. Five treatments of paclobutrazol and non-spray (control) were sprayed at 66 days, 56 days, 46 days and 36 days before heading (ie 30 days, 20 days, 10 days and the stage of jointing before jointing). Paclobutrazol treatment amount of 12 grams per mu, four times repeated. The results showed that spraying paclobutrazol between 66 days before heading and 36 days before heading all inhibited the growth of plant height
