施氮水平对通辽地区春大麦氮积累和转运的影响
The Influence of Different Nitrogen Levels to TongLiao Spring Barley Nitrogen Accumulation and Transportation
摘要
Abstract
Under different nitrogen levels,to reveal the accumulation and transportation regular of spring barley ni-trogen content in Tongliao district and making an analysis about the accumulation and transportation of two barley va-rieties organ nitrogen content on Inner Mongolia university for nationalities experimental base. The results indicating that with the increase of nitrogen levels, the leaf, stem and grain nitrogen content increased. Under the 270kg·hm-2 ni-trogen level, Mengpi 1 and Ganpi 4 maximum values of leaves respectively 53.25%and 36.31%higher than the con-trast and stems were 38.16%and 54.29% higher than the contrast, the grains were 21.88%and 21.22%higher than the contrast. With the increase of nitrogen levels, before flowering and after flowering the nitrogen accumulation of the two barley varieties are all increasing. Under the 270kg·hm-2 nitrogen level, Mengpi 1 and Ganpi 4 before flowering nitrogen accumulation respectively 297.42% and 198.65% higher than the contrast,after flowering 222.55% and 174.46% higher than the contrast.关键词
