Abstract: The experiment used cultivated rice varieties (lines) as materials, which was suitable for planting in the Third Accumulative Temperature Belt of Heilongjiang Province. The purpose of testing is to study the influence of rice morphological characteristics and yield under the salt stress and low-nutrition, and to screening barren-resistant materials and salinity-resistant materials. This study is significanable to the rice production and sustainable land use of Heilongjiang Province.Composite result of leaf number and panicle length data showed that 6 rice materials had stronger tolerance low-phosphorus stress, such as Longjing 29, 04-582, Longjing 21, 01-687, 05-4076 and 06-2351.
