摘要
生土施肥盆栽小黑麦试验结果表明:不同肥料处理对小黑麦幼苗生长状况及生理功能的影响有明显的差异,施用磷肥或在磷肥的基础上配施其他肥料,1)可促进小黑麦幼苗营养生长、增加叶面积,提高光合利用率;2)小黑麦幼苗叶片的丙二醛(MDA)、超氧化物歧化酶(SOD)、过氧化物酶(POD)含量明显低于肥料施用单一的处理,可增强小黑麦苗期的抗逆能力.
The test of triticale growed in flowerpots full of the fertilizer-deficited soil and fertilized was studied. The result showed that thegrowth and physiological function of young Triticale were different under different fertilizer treatments.Application of phosphate fertilizer or combined application of phosphaate fertilizer and other fertilizers has two special effects. Firstly,this fertilizing treatment can improve the vegetative growth of young triticale and increase the leaves area and photosynthetic efficiency. Secondly,it also can strengthen the resistant ability of triticale plant to adverse circumstances during its seedling phase because the contents of MDA、SOD and POD in the leaves of triticale plant are lower than those single fertilizing treatments.
