沙生冰草分蘖特性的初探

Tillering Feature of Agropyron Desertorum (Fisch.)Schult.

提出沙生冰草有三种分蘖根系类型,对沙生冰草群体充分利用外界环境是有重要意义的。果后营养期是主要的分蘖时期,而水分因子是关键因素,特别是提高草产量和种子产量的前提。

Three rooting forms were found in Agropyron desertorum(Fisch.)Schult,which is important for it to make efficient use of soil water and nutrients.Most tillers generated in the post-seeding stage,water regime is a critical factor affecting tiller generation,and ultimately which is the premise of the forage and seed yields.
