3) topdressing nitrogen
追施氮素
4) additional nitrogen
追施氮
1.
Early and late maturity lines of Italian ryegrass were used to study the effects of different additional nitrogen application levels on yields and feeding qualities of regrowth plant.
结果表明,2个品系的再生草干物质产量(DM)、可消化干物质产量(DDM)、粗蛋白含量(CP)和干物质体外消化率(IVDMD)均随追施氮量的增加而增加,而中性洗涤纤维含量(DNF)、酸性洗涤纤维含量(ADF)和非结构性碳水化合物含量(NSC)则呈下降趋势。
5) Nitrogenous fertilizer quantity
氮肥追施量
6) topdressing nitrogen fertilizer
叶面追施氮肥
1.
The effect of different density and topdressing nitrogen fertilizer on the quality and yield of spring wheat varieties Longmai-26 were analyzed in this paper.
不同密度与叶面追施氮肥对春小麦品种龙麦-26品质和产量的影响试验结果表明:不同密度对春小麦品质的影响表现为籽粒的蛋白质含量和面粉湿面筋含量随着密度的增加而降低;密度显著影响小麦的产量,在本试验条件下以600万株/hm2基本苗产量较高,密度过高和过低都不利于产量的形成;叶面追施氮肥可以增加籽粒蛋白质含量和面粉的湿面筋含量;低密度条件下叶面追施氮肥的增产幅度较大,而在中高密度条件下对产量的作用不大。
