- Abstract:
-
Root irrigation is a kind of new technology, which is able to deliver water directly to the roots of plants, and has the function of drought resistance and water retention. Using the root irrigation and drip irrigation experiment of Tamarix ramosissima, Elaeagnus angustifolia, Caragana korshinskii planted on abandoned lands was carried out. By measuring the change of soil moisture content and plant growth index under different irrigation methods, the supplies and maintaining action of two irrigation ways on soil moisture and positive impact on plant growth were examined. The results show that: (1) the range and depth of soil water supply are not consistent with the root irrigation and drip irrigation, the water mainly concentrated on the soil surface under the drip irrigation, while the water mainly concentrated below the 20 cm layer under the root irrigation, which is closely related with the irrigation time and irrigation amount; (2) root irrigation can keep the soil moisture better, while the surface soil water under drip irrigation can lost easily; (3) the growth of three species under root irrigation are greater than that under the drip irrigation, and root irrigation can better promote plant growth. Root irrigation is the ideal irrigation method on the three typical desert plants.
