| Based on the development of drip irrigation, subsurface drip irrigation(SDI)is a new kind of high-efficiency water saving irrigation。 This paper analyzed further soil-water movement and soil-salt transport of SD1 system , Based on analyzing and researching large quantity cultural heritage of domestic and international.. Moreover, the experiment of soil-water and salt transpor has been completed in the SDI conton farmland of 30 Regiment farm . Results show that soil texture, initial soil—water content, mche discharge rate, the mcHe—buried depth and so on are all the important parameters that have powerfulimpacts on soil—water movement of SDI system; In the SDI conton farmland of 30 Regiment farm , t he soil of 15~ 40 cm depth contain the water rate the variety big, keep to best contain the water appearance;In the cotton root area 20 ~ 50 cm formation the salt downplay the district, underground water level in the boundary depth below, main root of cotton area salt alkali the degree obviously lower, benefit to the cotton growth. |
