梭梭、白梭梭萌发过程的初探

针对准噶尔盆地南部沙漠边缘沙丘活化这一现象,结合目前新疆梭梭、白梭梭研究现状,结合历年的气象资料,模拟自然条件,对梭梭、白梭梭自然恢复的初始过程——种子萌发的温度和水分条件进行研究。结果表明,新疆梭梭、白梭梭种子在2℃时就可以萌发,而且发芽率达80%以上,当积雪厚度达到22 cm时,梭梭、白梭梭种子发芽率达到80%以上,变温提高发芽速率,当积雪厚度达到22 cm就可满足梭梭、白梭梭种子萌发的水分条件。此结果可为沙漠地区植被自然恢复提供理论依据。

Study on Natural Cure of Main Plant Species at Initialized Process in the South Marginal Zone of the Junggar Basin

Based on dune activation phenomenon in the south marginal zone of Junggar basin,integrated research actuality of Xinjiang haloxylon ammdendron and haloxylon persicum,perennial weather datum,the paper studies initialized process of natural cure and temperature and moisture condition of seed germination under simulating natural condition for haloxylon ammdendron and haloxylon persicum.The result shows seed germination is 2℃ and germinant probability is over 80%,meanwhile germinant probability is over 80% when snow thickness is 22cm,changing temperature can improve germinant speed,22cm snow thickness can meet moisture condition of seed germination for haloxylon ammdendron and haloxylon persicum.This research result provides theory supporting for plant natural cure in the desert region.
