| 摘 要： | 2007年5-9月在地处西辽河平原的内蒙古民族大学试验农场以6年生紫花苜蓿为试验对象,研究了施磷深度对紫花苜蓿生长及产量的影响.结果表明:在6cm、12cm和18cm 3个施磷深度处理下,株高差异不显著;1级分枝数在第1茬的差异不显著,在其它各茬的差异较大;处理间节间数差异不显著,节间距在第3茬、第4茬差异亦不显著;叶绿素a和叶绿素b差异显著,而类胡萝卜素差异不显著;年总草产量以6cm施磷处理下最高,且与其它2个施磷处理的差异达到极显著水平;返青率随施磷深度的增加而降低,这与深施磷肥对根系的伤害较重有关.从持续高产的角度来看,紫花苜蓿施磷以浅施为宜.

| Abstract: | Study on effects of phosphorus depth on growth and yield was carried on with six-year alfalfa on experimental farm of the Inner Mongolia University for Nationalities in Xiliaohe Plain from May to September in 2007.The results showed that: under the three phosphorus depth(6cm,12cm and 18cm),differences of plant heights were not obvious;differences of the number of first branch in the first stubble were not obvious but differences in the other three stubble were a little more obvious;differences of node numbe... |
