Abstract: The field planting test data and the recorded growth data of Nanju No.1 were obtained based on investigating the physiochemical properties of saline or alkaline soil of tidal flat.These data were finally sorted and summarized,and the SPSS 17.0 was used for the statistical analysis.Results were as follows: ① Nanju No.1 was able to adapt the saline or alkaline soil in west Jilin Province with its high yield and good adaptability.The introduction was relatively successful.The survival,wintering status and growth status of the Nanju No.1 on the light chernozem (pH 8.1) were significantly superior to those in the experimental field (pH 8.3).The survival rates of Nanju No.1 on light chernozem and sandy alkaline soil were 94.56% and 82.27% respectively,and the differences were significant (P<0.05); ② At the emergence stage,the dry matter accumulation of stems and leaves was slow; during the rapid growth period,the dry matter accumulation of stems and leaves began to transfer to underground; during the tuber expansion period,the nutrients absorbed by tubers increased rapidly.The dry matter accumulation and yield of Nanju No.1 on the light chernozem were significantly higher than that on the sandy alkaline soil.The dry matter accumulations of stems on the light chernozem and the sandy alkaline soil during the fast growing period reached 912.26 g·plant-1 and 756.02 g·plant-1,and the difference was significant (P<0.05); ③ The main factors affecting the survival and growth status of Nanju No.1 under the saline or alkaline stress in west Jilin Province were the moisture content,organic matter content and total nitrogen content in soil; ④ The improvement effect of Nanju No.1 on the light chernozem was significantly better than that on the sandy alkaline soil.In conclusion,Nanju No.1 could adapt to the light chernozem and the sandy alkaline soil well in west Jilin Province,and the light chernozem soil is more suitable for Nanju No.1.
