| Abstract: | Maize straw,which contains several kinds of nutrient element,is an important organic fertilizer source.Maize straw mulching in dry area,not only can reduce the volume weight and water evaporation of soil,but also can increase the soil porosity,soil organic matter and the content of nutrient elements including nitrogen,phosphorous and potassium.Meanwhile,it may promote the maize growth and increase the maize crop. |
