Effects of Different Nitraria tangutorum Species and Different Sowing Seasons on Seedling Growth
In order to find out the best species and sowing seasons of Nitraria tangutorum sowing and seedling cul-tivation in Alashan area,the seeds of Nitraria tangutorum and Nitraria sibirica were used as materials to carry out the contrast experiment of sowing seedlings by stages in winter and spring.The results showed as follows:the e-mergence rate of Nitraria tangutorum seedlings sown in spring was higher,whose height,diameter,number of roots,aboveground biomass and underground biomass were significantly higher than those of Nitraria sibirica seed-lings sown in spring,the growth indexes of Nitraria tangutorum were 36.22％,39.90％,80.89％,91.31％and 121.59％higher than those of Nitraria sibirica,respectively;the height of Nitraria tangutorum seedlings sown in winter was significantly higher than that of seedlings sown in spring.Therefore,it is considered that when sowing and cultivating seedlings in Alashan area,winter sowing of Nitraria tangutorum is beneficial to improve the emer-gence rate and growth and ensure the quality of seedlings.
