چکیده
The effects of drip irrigation and different cultivation methods on seed
germination and growth of Puccinellia tenuiflora in saline-sodic soils were
investigated in field experiments during 2008-2010 in the Songnen Plain, China.
Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for both
flat and ridge cultivation methods. Drip irrigation affected the distributions of
electrical conductivity of saturated-soil extract (ECe) and pH of the saline-sodic
soil. After cropping under drip irrigation for two years, the ECe and pH had
decreased greatly in the root zone on both the flat and ridge lands, and enabled
P. tenuiflora seeds to germinate and grow rapidly. In addition, the plant height,
number and length of spikes, coverage and aboveground biomass were all higher
on the flat than on ridge land, but the differences of the two cultivation methods
were not obvious. Compared to ridge planting, the flat planting method was more
convenient, and flat cultivation and drip irrigation may be appropriate for
restoration of saline-sodic grasslands.
