人工固沙区针毛收获蚁(Messor aciculatus F.Smith)自然蚁巢种子储藏格局研究

STORAGE PATTERNS OF SEED IN NATURAL NEST OF MESSOR ACTCULATUS F. SMITH IN THE PROTECTE DESERT

通过在人工固沙区对针毛收获蚁Messoraciculatus(F Smith)蚁巢的挖掘 ,发现该蚁主要收获 5种一年生草本植物种子 :狗尾草Setariaviridis、猪毛菜Salsolacollina、雾冰藜Bassiadasyphylla、地锦Euphorbiahumifusa、刺沙蓬Salsolaruthenica(Salsolapestifer)。不同巢穴深度种子储藏量不同。同一种种子在蚁巢的不同深度储藏量不同。同一巢穴深度不同种类种子储藏量也不同。

Through digging the nest of Messor aciulatus F Smith, it showed that the ant harvested 5 kinds of seeds of annual herbage plant: Setaria viridis? Salsola collina? Bassia dasyphylla?Euphorbia humifusa? Salsola ruthenica  The seeds of different nest segment were different quantity of storage The different stores mount of the same seed along the depth of nest The different category seeds of the same depth stores to measure too different The storage of seeds result in obvious descend of seeds germination
