摘要
通过2014—2015年开展播种量对小麦百农矮抗58生长的影响试验,结果表明:在试验设计的播种量下,生育期没有明显的区别,但随着播量的增加,无效分蘖的数量增加,降低了小麦的成籽数量,不利于小麦产量的提高,随着小麦的播种量从112.5 kg/hm^2增加到142.5 kg/hm^2,产量由8 254.5 kg/hm^2降低到7 902.0 kg/hm^2,降低幅度4.27%,达到极显著差异水平;112.5 kg/hm^2播种量处理与127.5 kg/hm^2处理之间没有显著差异。考虑成本,南阳市适宜的播种量为112.5 kg/hm^2。
Effects of sowing amounts on the growth of Bainong Aikang 58 were analyzed through the study in 2014 -2015 ,the results showed that in the sowing amounts in experiment design, there were no significant differences in the growth period, but the numbers of ineffective tiller increased, reduced the numbers of wheat seeds, it was not conducive to the improvement of wheat yield, with the sowing amounts of wheat increased from 112.5 kg/hm2 to 142.5 kg/hm~,productions were reduced from 8 254.5 kg/hm2 to 7 902.0 kg/hm2,reduced by 4.27% ,which achieved a very significant difference level.There were no significant differences between 112.5 kg/hm2 sowing amount treatment and 127.5 kg/hm： treatment.Considering the costs, the suitable sowing amounts in Nanyang City were 112.5 kg/hm2.
