Abstract

In rain-fed regions of two crops a year in northern China,the experiment was carried out to study the effects of bed-planting and mulching system,bed-planting system,flatting culture practice and and flatting culture oractice with mulching on physiology in leaf senescence of maize at later growth stage.The results indicated that as growth stage progress the activity of superoxide dismutase(SOD) reduced,and the content of malondialdehyde(MDA) increased.The content of chlorophyll began to decline from ten days after silking stage.The activity of superoxide dismutase(SOD) and the content of the chlorophyll was the highest under the ridge culture and mulch cultivation method,while the content of malondialdehyde(MDA) was the lowest.The treatment of bed-planting with mulching system also delayed leaves aging and maintained relatively high physiological function.The yield in bed-planting mulching system increased by 10.26%,4.24% and 13.34%,respectively,as compared with sowing on ridges system,flatting culture and mulching,flatting culture.
